Thermal spraying - Metallic and other inorganic coatings - Zinc, aluminium and their alloys (ISO 2063:2005)
This standard applies to thermal-sprayed metallic coatings for the protection of iron and steel against corrosion by applying zinc or aluminium or their alloys to uncoated surface to be protected.
This standard deals with characteristic properties and gives test methods for coatings obtained by the spraying of zinc and aluminium and their alloys for the general purpose of corrosion protection.
It gives firstly the definition, classification and symbols for these coatings in relation to their thickness.
It then deals with the preparation of surfaces, application of coatings and their characteristic properties: namely, thickness, appearance and adhesion.
Finally it gives test methods for checking these properties.
For other metals some of the provisions are valid and can be adopted by agreement between the interested parties.

EN ISO 2063:2005 (E) 4 Introduction Thermal-sprayed metallic coatings are produced by heating the coating metal to its molten stage and projecting it in a stream of gas onto the prepared surface to be coated. It is essential that the purchaser specifies the coating metal or alloy and the thickness of the coating required: merely to ask for thermal metal spraying to be carried out in accordance with this standard, without this information, is insufficient. It is essential that the design of the article is such that it may be coated properly. SIST EN ISO 2063:2005SIST EN ISO 2063:2005

This classification gives a series of thickness values applicable to zinc, aluminium and Zn-Al alloy coatings. Intermediate values may be specified by agreement between the parties concerned. The symbol corresponding to each coating shall be composed of the symbol according to EN ISO 14919 followed by the minimum local thicknessd. a In conformity with EN ISO 2064. b Thicknesses requiring an agreement between the interested parties, notably on the spraying technique used to achieve uniformity of
thickness, the use of paints or sealers and the test methods. c By special agreement between the interested parties, greater minimum thicknesses may be used if the coating obtained remains in
conformity with this standard. d To specify an alloy coating, the chemical symbol corresponding to EN ISO 14919 shall be followed by the minimum local thickness e. g. a
coating of 120 µm consisting of thermal spray material according to ZnAl15 alloy shall be specified as (EN ISO 14919 ZnAl15) 120, the
parentheses being essential for the identification of the alloy terms.
6 Manufacture 6.1 Preparation of surfaces to be coated by thermal spraying1)
The surface shall be thoroughly cleaned and roughened by blasting using a suitable abrasive grit. Blasting shall be continued until the surface has a metallic appearance and uniform texture according to EN ISO 8501-1, grade Sa 3. Immediately before spraying, the surface shall be dry and free from dust, grease, scale, rust and any contaminants. In all cases, the roughness of the surface shall be verified by comparison with a reference surface having similar properties to the workpiece, prepared according to specifications agreed between the interested parties. Unless otherwise specified, one of the following abrasives shall be used in the preparation of the surface: hematitic chilled cast iron grit according to EN ISO 11124-2; copper refinery slag according to EN ISO 11126-3;

In certain cases2), other abrasives may be used, by agreement between the interested parties, but with special precautions to achieve sufficient cleanliness and roughness to ensure the adhesion of the sprayed material. The grit size of the abrasive is generally between 0,5 mm and 1,5 mm. The abrasive used, whatever its type, shall be clean, dry and not contaminated. In the case of abrasive blasting using compressed air, the air shall be sufficiently clean and dry to prevent contamination of the abrasive or the surface to be sprayed w
