Metallic coatings - Physical vapour-deposited coatings of aluminium - Specification and test methods

1 Scope

This Standard specifies requirements for aluminium coatings applied by physical vapour deposition techniques to mild steels, low-alloy steels, high-strength steels, corrosion-resisting steels, aluminium alloys, titanium alloys and other materials, as appropriate. Physical vapour-deposited coatings of aluminium are not suitable for steels having tensile strengths greater than 1 400 MPa, because of the possibility of hydrogen embrittlement due to corrosion in service or storage, or as a result of excessive cathodic protection. WARNING. The use of this Standard may involve hazardous materials, operations and equipment. This Standard does not address all the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices, and to determine the applicability of regulatory limitations prior to use.
