It is recommended, therefore, that this specifications not be specified for new designs. The Aerospace Materials Division, however, does not recommend these specifications for future use in new designs. Similar but not necessarily identical processes are covered in the following specifications. AMS-CB is therefore reinstated and is designated as a noncurrent document.

The coating is intended for use when hard and smooth surfaces are required on coated parts.
Excellent uniform deposits are produced on irregular parts. Coated parts--that is, those parts used in air compressors, missile-fuel injector plates, pumps, reciprocating surfaces, and so forth are protected from oxidation, corrosion and wear. With aluminum electronic devices, not only is product contamination prevented, but the coated parts facilitate soldering when used in conjunction with a mildly activated RMA or activated RA rosin flux.
Coated parts of stainless steel similarly facilitate brazing. Browse Publishers. Top Sellers. My Account. Corporate Sustainability. Investor Relations. All Rights Reserved. Update Cart. Create New Account.
Electroless Nickel Plating
There are four 4 different classes and three 3 different grades of electroless nickel plating used throughout the industry to meet different specifications. The class of an electroless nickel plating refers to the post-plating heat treatment process that is used; the grade of an electroless nickel plating refers to its thickness. Heat treatment after electroless nickel plating provides evidence of proper adhesion and improves the crystalline structure of the amorphous deposit for greater hardness. Six heat-treat classes are available. Class 1 is for electroless nickel coatings that require no heat treatment.
MIL-C-26074 E Electroless Nickel Plating
Electroless nickel plating is an process that codeposits a nickel-phosphorous alloy without need for an externally applied electrical current. The electroless nickel plating process occurs from a chemical reduction of the nickel ions within the electroless nickel solution onto a metallic substrate rather than deposition of the ions from an applied current. As a result, the electroless nickel deposit is free of many of the problems associated with traditional electrolytic nickel including edge buildup and non-uniform coating. Electroless nickel deposits are extremely uniform, corrosion and erosion resistant and provide excellent lubricity. APT offers loose-piece barrel, rack and vibratory electroless nickel plating on nearly any metallic substrate including nearly any ferrous, cupreous and aluminum alloys as well as many exotic alloys. The electroless nickel phosphorous content affects the properties of the deposit significantly including hardness, corrosion resistance and magnetism.
