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.

Summary	This Standard specifies the low-carbon steel, low alloy steel, high strength steel, corrosion-resistant steel, aluminum, titanium alloy, and the technical requirements of other suitable base metal physical vapor deposition coating on aluminum. PVD aluminum coating is not suitable for tensile strength> 1400 MPa of various steel, since these steels in use, storage or excessive corrosion cathodic protection during may cause hydrogen embrittlement phenomenon.
