29、f this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.ISO 14232:2000, Thermal spraying Powders Composition and technical supply conditionsISO 14919:2001, Thermal spraying Wires,
30、rods and cords for flame and arc spraying Classification Technical supply conditions3 GeneralCoatings may be indicated with the general recommendations for technical drawings. To apply this symbolic representation will make sense in cases, where the thermally sprayed coating is very thin and/or may
31、be built up by several dissimilar coatings one upon another.The symbolic representation shall give clearly all necessary indications regarding the specific coating to be obtained without over-burdening the drawing with notes or showing an additional view or detail enlargement.This symbolic represent
32、ation includes an elementary symbol and one or more supplementary symbols and further complementary indications.If a large number of instructions for producing the coating have to be mentioned, it is recommended to indicate the specific instructions on the drawing or to define them in a separate par
33、ts list, if applicable (see Figures 6 and 7).4 SymbolsThe elementary symbol shall indicate that this process deals with thermal spraying.The following information shall be given by supplementary symbols: type of coating (bond or top coat); the spraying process and subsequent treatments.The following
34、 requirements may be defined by further additional instructions: the coating thickness needed or the final coating thickness machined, respectively; the spray material to be used; surface condition; post-treatments of coating; a technical specification, which defines requirements necessary to comple
35、te the coating.
