Metallic materials - Instrumented indentation test for hardness and materials parameters - Part 4: Test method for metallic and non-metallic coatings (ISO 14577-4:2016)
ISO 14577-4:2016 specifies a method for testing coatings which is particularly suitable for testing in the nano/micro range applicable to thin coatings. However, the application of this method of this part of ISO 14577 is not needed if the indentation depth is such a small fraction of the coating thickness that in any possible case a substrate influence can be neglected and the coating can be considered as a bulk material. Limits for such cases are given.
This test method is limited to the examination of single layers when the indentation is carried out normal to the test piece surface, but graded and multilayer coatings can also be measured in cross-section if the thickness of the individual layers or gradations is greater than the spatial resolution of the indentation process.
The test method is not limited to any particular type of material. Metallic and non-metallic coatings are included in the scope of this part of ISO 14577. In this part of ISO 14577, the term coating is used to refer to any solid layer with homogeneous properties different to that of a substrate it is connected to. The method assumes that coating properties are constant with indentation depth. Composite coatings are considered to be homogenous if the structure size is less than the indentation size.
The application of this part of ISO 14577 regarding measurement of indentation hardness is only possible if the indenter is a pyramid or a cone with a radius of tip curvature small enough for plastic deformation to occur within the coating. The hardness of visco-elastic materials or materials exhibiting significant creep will be strongly affected by the time taken to perform the test.

Matériaux métalliques - Essai de pénétration instrumenté pour la détermination de la dureté et de paramètres des matériaux - Partie 4 : Méthode d'essai pour les revêtements métalliques et non métalliques (ISO 14577-4:2016)
ISO 14577-4:2016 spécifie une méthode d'essai pour les revêtements qui convient particulièrement pour soumettre à essai dans la plage nano-micro, applicable aux revêtements minces. Cependant l'application de la méthode de la présente partie de l'ISO 14577 n'est pas nécessaire si la profondeur de pénétration correspond à une fraction si petite de l'épaisseur du revêtement que, dans tous les cas possibles, une influence du substrat peut être négligée et le revêtement peut être considéré comme un matériau massif. Les limites de tels cas sont données.
La présente méthode d'essai est limitée à l'examen des couches simples lorsque l'empreinte est réalisée perpendiculairement à la surface de l'éprouvette, mais les revêtements avec une gradation ou comportant plusieurs couches peuvent également faire l'objet de mesures dans la section si l'épaisseur des couches individuelles ou des zones où la dureté évolue est supérieure à la résolution spatiale du processus de pénétration.
La méthode d'essai n'est pas limitée à un quelconque type particulier de matériau. Les revêtements métalliques et non métalliques sont inclus dans le domaine d'application de la présente partie de l'ISO 14577, le terme revêtement est utilisé pour désigner toute couche solide de caractéristiques homogènes différentes de celles du substrat à laquelle elle est reliée. La méthode suppose que les propriétés du revêtement sont constantes avec la profondeur de pénétration. Les revêtements composites sont considérés homogènes si la taille de la structure est inférieure à la taille de l'empreinte.
L'application de la présente partie de l'ISO 14577 en ce qui concerne la mesure de la dureté est possible seulement si le pénétrateur est une pyramide ou un cône avec un rayon de courbure de la pointe suffisamment petit pour que la déformation plastique se produise à l'intérieur du revêtement. La dureté des matériaux visco-élastiques ou des matériaux présentant un fluage significatif sera largement influencée par le temps utilisé pour réaliser l'essai.
Kovinski materiali - Preskus trdote in lastnosti materialov z instrumentirano metodo vtiskovanja - 4. del: Preskusna metoda za kovinske in nekovinske prevleke (ISO 14577-4:2016)
Ta de standarda ISO 14577 določa metodo za preskušanje prevlek, ki je še posebej primerna za preskušanje na nano/mikro ravni, ki se uporablja za tanke prevleke. Vendar uporaba te metode iz tega dela standarda ISO 14577 ni potrebna, če globina vtisa predstavlja tako majhen delež debeline prevleke, da je v vseh možnih primerih mogoče zanemariti vpliv podlage in se lahko prevleka obravnava kot razsuti material. Podane so omejitve za takšne primere.
Ta preskusna metoda je omejena na pregled posameznih slojev, ko je izveden
običajen vtis na površino preskušanca, vendar se lahko stopenjske in večslojne prevleke merijo tudi v preseku, če je debelina posameznih slojev ali prehodov večja od prostorske ločljivosti postopka vtiskovanja.
Preskusna metoda ni omejena na nobeno določeno vrsto materiala. Kovinske in nekovinske prevleke spadajo na področje uporabe tega dela standarda ISO 14577. V tem delu standarda ISO 14577 se izraz »prevleka« uporablja za vsak trden sloj s homogenimi lastnostmi, ki se razlikujejo od lastnosti podlage, s katero je spojen sloj. Metoda predpostavlja, da so lastnosti prevleke konstantne z globino vtisa. Kompozitne prevleke se štejejo za homogene, če je velikost strukture manjša od velikosti vtisa.
Uporaba tega dela standarda ISO 14577 o merjenju trdote vtisa je mogoča
le, če je vtisno telo piramida ali stolpec z dovolj majhnim polmerom ukrivljenosti konice, da pride do plastične deformacije prevleke. Na trdoto viskoelastičnih materialov ali materialov z visoko stopnjo lezenja močno vpliva čas, potreben za izvajanje preskusa.
OPOMBA 1: Standardi ISO 14577-1, ISO 14577-2 in ISO 14577-3 opredeljujejo uporabo preskušanja z instrumentiranim vtiskovanjem pri razsutih materialih v vseh razponih sile in premaknitev.
OPOMBA 2: Tukaj uporabljena analiza ne dovoljuje kopičenja ali udiranja vtisov. Uporaba atomske mikroskopije (AFM) za oceno oblike vtisa omogoča ugotavljanje možnega kopičenja ali udiranja površine okoli vtisa. Ti površinski vplivi povzročajo podcenitev (kopičenje) ali precenitev (udiranje) kontaktnega območja pri analizi, kar lahko vpliva na izmerjene rezultate. Kopičenje se običajno pojavi pri popolnoma deformacijsko utrjenih materialih. Kopičenje mehkih duktilnih materialov je verjetnejše pri tanjših prevlekah zaradi omejitev obremenitev v območju plastične deformacije prevleke. Poročila navajajo, da kopičenje materiala povzroči učinkovito povečanje kontaktnega območja za ugotavljanje trdote, medtem ko je učinek manj opazen pri ugotavljanju modula vtiskovanja, ker je nakopičen material manj trden.[1][2]

Introduction
The elastic and plastic properties of a coating are critical factors determining the performance of the
coated product. Indeed, many coatings are specifically developed to provide wear resistance that is
usually conferred by their high hardness. Measurement of coating hardness is often used as a quality
control check. Young’s modulus becomes important when calculation of the stress in a coating is
required in the design of coated components. For ex
