Advanced technical ceramics - Methods of test for ceramic coatings - Part 13: Determination of wear rate by the pin-on-disk method
1.1 This part of EN 1071 describes a method for evaluating the wear of ceramic coatings by use of a test in which a flat or spherically ended pin is brought, under load, into contact with the flat surface of a disk and the two are set in relative motion such that the pin describes a circular path on the disk. Depending on the conditions being simulated, either the pin or disk or both may be coated with the material under test, with the other member of the couple being selected for its relevance to the system under evaluation.
1.2 Where suitable equipment is available, the test may be used to determine the friction generated in the sliding contact.
1.3 The method is suitable for evaluating coatings in the thickness range from 1 to more than 100μm, and with suitable choice of conditions might also be applicable to testing thinner coatings.
1.4 Testing may be under either dry or lubricated conditions. However, the test is not designed for evaluating the properties of lubricants except in so far as they affect the wear behaviour of the materials being tested. Related methods for testing lubricants using a reciprocating motion are given in references [4] – [6].
1.5 Testing a materials couple under a range of loading conditions might provide information about the adhesive and/or cohesive strength of the coating, in addition to its wear behaviour.
Hochleistungskeramik - Verfahren zur Prüfung keramischer Schichten - Teil 13: Bestimmung der Verschleißrate mittels Stift-Scheibe-Prüfung
1.1 In diesem Teil von EN 1071 wird ein Prüfverfahren zur Bewertung des Verschleißes keramischer Schichten festgelegt, bei dem ein Prüfstift mit flachem oder kugelförmigem Ende unter Krafteinwirkung mit der ebenen Oberfläche einer Scheibe in Kontakt gebracht und die beiden so relativ zueinander bewegt werden, dass der Stift auf der Scheibe einen kreisförmigen Weg durchläuft. In Abhängigkeit von den zu simulierenden Bedingungen dürfen entweder der Stift oder die Scheibe oder beide mit dem zu prüfenden Werkstoff beschichtet sein, wobei das andere Element der Werkstoffpaarung hinsichtlich seiner Relevanz für das zu untersuchende System ausgewählt wird.
1.2 Wenn eine geeignete Prüfeinrichtung verfügbar ist, darf die Prüfung zur Bestimmung der beim Gleit-kontakt auftretenden Reibung angewendet werden.
1.3 Dieses Verfahren ist zur Bewertung von Schichten mit Dicken von 1 µm bis größer 100 µm geeignet; durch Auswahl entsprechender Bedingungen ist das Verfahren auch auf dünnere Schichten anwendbar.
1.4 Die Prüfung darf trocken oder mit Schmierung durchgeführt werden. Die Prüfung ist jedoch nicht zur Bewertung der Schmierstoffeigenschaften vorgesehen, außer insoweit, wie Schmierstoffe das Verschlei߬ver-halten der zu prüfenden Werkstoffe beeinflussen. Verfahren zur Prüfung von Schmierstoffen unter Anwen-dung einer Hin und Herbewegung werden in [4] bis [6] angegeben.
1.5 Die Prüfung einer Werkstoffpaarung unter unterschiedlichen Beanspruchungsbedingungen kann außer Informationen zum Verschleißverhalten der Schicht auch Angaben zu ihrer Haft und/oder Kohäsionsfestigkeit liefern.
Céramiques techniques avancées - Méthodes d'essai pour revêtements céramiques - Partie 13 : Détermination du taux d'usure selon la méthode pin-on-disk
1.1 Cette norme européenne décrit une méthode d’évaluation de l’usure des revêtements céramiques à
l’aide d’un essai dans lequel une broche à extrémité plate ou sphérique, sous charge, en contact avec un
disque plat, est mise en mouvement relatif avec ce dernier de sorte que la broche décrive un chemin circulaire
sur la surface plane du disque. Selon les conditions simulées, la broche ou le disque, ou les deux, peuvent
être revêtues du matériau soumis à essai, l’autre membre du couple étant sélectionné pour sa pertinence par
rapport au système soumis à évaluation.
1.2 Lorsque les équipements appropriés sont disponibles, l’essai peut être utilisé pour déterminer le
frottement généré dans le contact de glissement.
1.3 La méthode est adaptée à l’évaluation des revêtements dans une plage d’épaisseur comprise entre
1 μm et plus de 100 μm, et en choisissant des conditions appropriées, elle peut également s’appliquer aux
essais réalisés sur des revêtements plus minces.
1.4 Les essais peuvent être effectués à l'état sec ou lubrifié. Néanmoins, les essais ne sont pas destinés à
évaluer les propriétés des lubrifiants, sauf dans la mesure où celles-ci influencent le comportement à l'usure
des matériaux soumis à essai. Les méthodes d’essai associées des lubrifiants par un mouvement de va-etvient
sont données dans les références [4] à [6].
1.5 L’essai effectué sur un couple de matériaux dans une plage de conditions de charge peut fournir des
informations relatives à la résistance adhésive et/ou cohésive du revêtement, outre son comportement à
l’usure.
Sodobna tehnična keramika - Metode za preskušanje keramičnih prevlek - 13. del: Ugotavljanje stopnje obrabe (metoda pin-on-disk)
Ta evropski standard opisuje metodo za ocenjevanje obrabe keramičnih prevlek z uporabo preskusa, pri katerem plosko ali kroglasto zaključeno iglo privedemo v stik, pod obtežbo, z ravno površino diska, nato pa oba poženemo v relativno gibanje tako, da igla opiše krožno pot na disku. V odvisnosti od simuliranih pogojev sta lahko bodisi igla ali disk, ali oba, prevlečena z materialom, ki se preskuša, pri čemer je drugi del para izbran zaradi svoje pomembnosti za sistem, ki se ocenjuje. Kadar je na voljo ustrezna oprema, se preskus lahko uporablja za določevanje trenja, ki nastaja pri drsečem stiku. Metoda je primerna za ocenjevanje prevlek v razponu debeline od 1 μm do več kot 100 μm, z ustreznim izborom pogojev pa se lahko uporablja tudi za preskušanje tanjših prevlek. Preskus se lahko opravi bodisi pod suhimi ali mazanimi pogoji. Vendar pa preskus ni zasnovan za ocenjevanje lastnosti maziv, razen v kolikor vplivajo na obnašanje preskušanih materialov pri obrabi. Povezane metode za preskušanje maziv z uporabo izmeničnega gibanja so podane v referencah [4] - [6]. Preskušanje para materialov pod razponom obtežbenih pogojev lahko zagotovi podatke o sprijemni in/ali kohezijski trdnosti prevleke, poleg njegovega obnašanja glede obrabe.

SIST EN 1071-13:2010
Introduction The determination of the wear resistance of thin ceramic coatings used in sliding contacts is of high importance in several industrial fields such as stamping, moulding, blanking and in many situations where two mechanical components slide on each other. This part of EN 1071 describes a method for evaluating the wear of ceramic coatings by use of a test in which a flat or spherically ended pin is brought, under load, into contact with a flat disk and the two are set in relative motion such that the pin describes a circular path on the flat surface of the disk. Depending on the information required, either the disk or pin or both may be coated with the material under test, with the other member of the couple being selected for its relevance to the tribosystem under evaluation. Wear is determined by weight loss, by profilometry, by linear measurement or by a combination of these.
Testing may be carried out under dry or lubricated conditions. Where suitable instrumentation is available, the test can provide important information about the friction generated in the system. In addition to providing data on the frictional interaction in the system, monitoring of the friction can, by detecting changes in the level or trend of the friction force, provide important information about changes occurring during the test, e.g. removal or fracture of the coating, changes in wear mechanisms, etc. The test for use with bulk materials sliding under non-lubricated conditions is well described in [1]. This standard identifies the basic equipment requirements and the test critical parameters for testing ceramic coatings, and provides for appropriate operating procedures and measurement protocols to ensure their proper control. In addition, it provides for consistency in the analysis of data and in the treatment of errors.
This part of EN 1071 complements parts 6 [2] and 12 [3], which describe techniques for micro-scale abrasion wear testing and reciprocating wear testing of ceramic coatings respectively. SIST EN 1071-13:2010
1 Scope 1.1 This European Standard describes a method for evaluating the wear of ceramic coatings by use of a test in which a flat or spherically ended pin is brought, under load, into contact with the flat surface of a disk and the two are set in relative motion such that the pin describes a circular path on the disk. Depending on the conditions being simulated, either the pin or disk or both may be coated with the material under test, with the other member of the couple being selected for its relevance to the system under evaluation.
1.2 Where suitable equipment is available, the test may be used to determine the friction generated in the sliding contact. 1.3 The method is suitable for evaluating coatings in the thickness range from 1 µm to more than 100 µm, and with suitable choice of conditions might also be applicable to testing thinner coatings. 1.4 Testing may be under either dry or lubricated conditions. However, the test is not designed for evaluating the properties of lubricants except insofar as they affect the wear behaviour of the materials being tested. Related methods for testing lubricants using a reciprocating motion are given in references [4] – [6]. 1.5 Testing a materials couple under a range of loading conditions might provide information about the adhesive and/or cohesive strength of the coating, in addition to its wear behaviour. 2 Normative references The following referenced documents are indispensable for the application of this document.
