DIN EN ISO 14921-2011 热喷涂.工程零件热喷涂涂层的应用步骤(ISO 14921-2010);德文版本EN ISO 14921-2010
Thermal spraying - Procedures for the application of thermally sprayed coatings for engineering components (ISO 14921:2010); German version EN ISO 14921:2010
This International Standard specifies the general procedure, when a thermally sprayed coating is applied to enhance the surface properties of a component or to reclaim worn and non-conforming parts.
This International Standard does not provide definitive methods for specific work due to the variety of the technological, physical and/or chemcial requirements and of the component's shape.
This International Standard specifies the general conditions for the selection of the spraying procedure and materials for the purpose. It does not apply to thermally sprayed zinc and/or aluminium coatings for protection of steel structures against atmospheric corrosion, for which ISO 2063 applies.
This International Standard also does not apply to coatings of self-fluxing alloys which are subsequently fused. That procedure is covered by ISO 14920.
