EN 13507:2018 (E) 3 European foreword This document (EN 13507:2018) has been prepared by Technical Committee CEN/TC 240 “Thermal spraying and thermally sprayed coatings”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2019, and conflicting national standards shall be withdrawn at the latest by February 2019. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13507:2010. This third edition of EN 13507 cancels and replaces EN 13507:2010, which has been technically revised and, in addition to the change in number, contains the following changes: — update of normative references; — Revision of subclause 5.6 (Bond coatings). According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 13507:2018 (E) 4 1 Scope This document specifies the processing of surface preparation for thermal spraying. Important principles indicated in this European Standard are intended to be taken into consideration when surfaces of metallic parts are to be prepared for thermal spraying. This document applies for production of new parts as well as for the repair of worn parts. This document does not apply for thermal spraying in the case of protection against atmospheric corrosion by coatings of zinc and/or aluminium and their alloys, for which EN ISO 2063-1:2017 and EN ISO 2063-2:2017 apply. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

To achieve a sufficient adhesive strength the metallic surface shall be processed until a technically clean interface is generated. The surface to be prepared shall be accessible for grit blasting. EN 15520 gives information regarding suitable component design. Welding splashes and residues of welding slag shall be removed, and weld seams and brazed or soldered joints shall be prepared with particular accuracy. Oxides, oil, grease and other contamination shall be removed. SIST EN 13507:2018



EN 13507:2018 (E) 5 The roughness of the surface shall enable a good interlocking of the sprayed coating to the substrate. Grit blasting is a suitable method for obtaining appropriate roughened metallic surfaces, thereby also enlarging the effective area. The surface to be sprayed shall be kept dry during the preparation and spraying process. For outdoor spraying this requirement shall be met by taking suitable precautions. The prepared surface shall be coated subsequently after carrying out the grit blasting without any undue loss of time1). 5 Methods of surface preparation 5.1 General Depending upon the function of the sprayed coating and the initial condition of the surface, different preparation procedures are used. In any case scale, rust, dust and other contaminants shall be removed by mechanical cleaning. 5.2 Degreasing Oil and grease contaminants shall be removed thoroughly prior to processing the surface. In particular attention shall be given to bores, slots and channels. Design of components shall be such that fluids can drain out. Degreasing can be done by heating, dipping and spraying processes with or without additional mechanical support by ultrasonic cleaning, brushing or steam jet blower. Aqueous wash solutions or organic solvents are suitable. For the application of wash solutions a mild alkaline cleaner with a high content of surfactants may be preferred. Whenever possible cleaner free of phosphate should be used. The application of chlorinated or fluorinated hydrocarbons should be avoided due to their detrimental effect on health and the environment. Subsequent rinsing and drying is necessary. For health, safety and environment aspects see 5.7. 5.3 Grit blasting 5.3.1 Cleanliness For thermal spraying the surface shall be sufficiently cleaned and roughened by applying a suitable grit. The grit blasting process shall be continued until the area to be coated shows a metallic surface with a uniform structure according to EN ISO 8501-1 Sa 3. Unwanted loss of material, which can occur by excessive blasting, shall be considered. Generally, the preparation grade Sa 3 is necessary but often not sufficient for the purpose. I
