Metallic and other inorganic coatings. Phosphate conversion coating of metals Ingestion-build-109673 b) for butt welding endWhat is this standard about? It specifies requirements for how ferrous metals, aluminium, zinc, cadmium and their alloys should be processed to produce coatings that essentially consist of inorganic phosphates. These coatings will be used in conjunction with supplementary finishes to protect the basis metal against corrosion and to provide anti wear properties to sliding surfaces; adhesion to organic finishes; and ease of cold forming operation.
