EN 13507:2010 (E) 4 1 Scope This European Standard specifies the processing of surface preparation for thermal spraying. Important principles indicated in this European Standard should be taken into consideration when surfaces of metallic parts are to be prepared for thermal spraying. This European Standard applies for production of new parts as well as for the repair of worn parts. This European Standard 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 applies. 2 Normative references The following referenced documents are indispensable for the application 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. EN ISO 8501-1, Preparation of steel substrates before application of paints and related products — Visual assessment of surface cleanliness — Part 1: Rust grades and preparation grades of uncoated steel substrates and of steel substrates after overall removal of previous coatings (ISO 8501-1:2007) EN ISO 11124-1, Preparation of steel substrates before application of paints and related products — Specifications for metallic blast-cleaning abrasives — Part 1: General introduction and classification (ISO 11124-1:1993) EN ISO 11124-2, Preparation of steel substrates before application of paints and related products — Specifications for metallic blast-cleaning abrasives — Part 2: Chilled-iron grit (ISO 11124-2:1993) EN ISO 11126-1, Preparation of steel substrates before application of paints and related products — Specifications for non-metallic blast-cleaning abrasives — Part 1: General introduction and classification (ISO 11126-1:1993, including Technical Corrigenda 1:1997 and 2:1997) 3 Principles The surface preparation of a work piece has a substantial effect on the quality of the sprayed coating especially with regard to its adhesion to the substrate. 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. 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. SIST EN 13507:2010
EN 13507:2010 (E) 5 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). 4 Methods of surface preparation 4.1 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. 4.2 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 4.7. 4.3 Grit blasting 4.3.1 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. If necessary, the required condition of cleanliness and roughness shall be agreed between the contracting parties. The preparation by grit blasting will vary depending on the type and size of the abrasive, blasting parameters, e.g. blasting time, d
