1. Scope | ||||||||||||||||||||||||||||||||||||
1.1 This specification covers the requirements for a cadmium coating vacuum-deposited on iron and steel basis metals. The coating is especially beneficial to those ferrous metals, heat treated to 46HRC and higher or having an ultimate tensile strength greater than 1500 MPa, wherein protection against corrosion and appearance are important (see Appendix X1). 1.2 Vacuum-deposited production items are normally free of hydrogen embrittlement, a danger when using electroplating processes for deposition. Vacuum deposition can handle large high-strength parts that cannot be conveniently mechanically plated in the rotating barrels. 1.3 The coating is provided in various thicknesses up to and including 12 μm (3.1) either in the as-deposited condition or with a supplementary finish (3.2). 1.4 The following precautionary caveat pertains
only to the test methods portion, Section 9, of this specification:
