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
