ISO 14921:2010 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.
ISO 14921:2010 does not provide definitive methods for specific work due to the variety of the technological, physical and/or chemical requirements and of the component's shape.
ISO 14921:2010 specifies the general conditions for the selection of the spraying procedure and materials for this purpose. ISO 14921:2010 does not apply to thermally sprayed zinc and/or aluminium coatings for protection of steel structures against atmospheric corrosion, for which ISO 2063 applies.
ISO 14921:2010 also does not apply to coatings of self-fluxing alloys which are subsequently fused. That procedure is covered by ISO 14920.
