Scope. This specification covers requirements for an electrodeposited zinc‐nickel (Zn‐Ni) alloy plating with a hexavalent chromium‐free conversion coating and supplementary top coat or sealant. This MIL specification selects desired options from ASTM F1941/F1941M and details additional...
4.1 The performance and quality of electroplated or conversion-coated zinc alloy die casting depends upon the surface cleanliness and condition. Various metals are electroplated or conversion coatings are established on zinc alloys for decorative or engineering finish....
This specification establishes the requirements for electrodeposited zinc coatings applied to iron or steel articles for corrosion protection purposes. Electrodeposited zinc-coated steel wires or sheets are not covered here. The coatings shall be provided in four standard thickness...
1.1 This test method covers the Corrodkote2 method of evaluating the corrosion performance of copper/nickel/chromi
1.1 This specification covers the requirements for electrodeposited cadmium coatings on products of iron, steel, and other metals. Note 1: Cadmium is deposited as a coating principally on iron and steel products. It can also be electrodeposited on aluminum, brass, beryllium copper, copper, nickel,...
1.1 This specification covers the requirements for a coating of cadmium mechanically deposited on metal products. The coating is provided in various thicknesses up to and including 12 μm. 1.2 Mechanical deposition greatly reduces the risk of hydrogen embrittlement and is suitable for coating bores...
1.1 This specification covers the requirements for electrodeposited zinc cobalt alloy coatings on metals. 1.2 The following precautionary caveat pertains to the test method portion only, Section 8, of this specification: This standard does not purport to address all of the safety concerns,...
3.1 Various metals are deposited on aluminum alloys to obtain a decorative or engineering finish. The electroplates applied are usually chromium, nickel, copper, brass, silver, tin, lead, cadmium, zinc, gold, and combinations of these. Silver, tin, or gold is applied to electrical...
1.1 This specification covers the requirements for electrodeposited (electroplated) coatings of tin applied to metallic articles. Tin coatings are used to provide a low contact-resistance surface, to protect against corrosion (see 1.2), to facilitate soldering, to provide anti-galling...
This specification covers the design, material, and minimum performance requirements for resilient connectors used to provide a positive seal between the pipe and manholes or other structures subjected to internal and external hydrostatic pressures less than 10.8 psi [74 KPa]. Testing under this...
1.1 This practice covers a preferred method for evaluating the condition of electroplated test panels that have been exposed to corrosive environments for test purposes. It is based on experience in use of the method with standard 10- by 15-cm (4- by 6-in.) panels exposed on standard ASTM...
1.1 This guide describes two processes used for plating on magnesium and magnesium alloys: direct electroless nickel plating and zinc immersion. Some users report that the direct electroless nickel procedure does not produce quite as high a level of adhesion as zinc immersion. 1.2 The...
The materials defined by these specifications are corrosion protective coatings over steel and iron substrates. All consist of electrolytic or non-electrolytic zinc plating with trivalent chromium passivate. A2, A3 and A4 are also coated with a clear sealer to increase corrosion resistance...
This document specifies requirements for electroplated coatings of zinc with supplementary treatments on iron or steel. It includes information to be supplied by the purchaser to the electroplater, and the requirements for heat treatment before and after electroplating....
The materials defined by these specifications are corrosion protective coatings over steel and iron substrates. All consist of an alkaline zinc nickel alloy and trivalent chromium passivate. A2, A3, A4, A5 and A6 are also coated with a clear sealer to increase corrosion resistance and/or to...
This document specifies requirements for electroplated coatings of zinc with supplementary treatments on iron or steel. It includes information to be supplied by the purchaser to the electroplater, and the requirements for heat treatment before and after electroplating....
ISO 2081:2018 specifies requirements for electroplated coatings of zinc with supplementary treatments on iron or steel. It includes information to be supplied by the purchaser to the electroplater, and the requirements for heat treatment before and after electroplating....
Scope. This specification covers the electro-deposition of a Low Hydrogen Embrittlement (LHE) zinc-nickel alloy containing 12-15 percent nickel. LHE alkaline zincnickel alloy electroplating meeting this specification is an alternative for cadmium as a corrosion control coating.
3.1 A variety of metals can be electrodeposited on plastics for decorative or engineering purposes. The most widely used coating consists of three layers-copper plus nickel plus chromium-for decorative applications. However, brass, silver, tin, lead, cadmium, zinc, gold, other metals, and...
1.1 This practice covers the procedure for locating, by the use of a solution of copper sulfate, the thinnest spot in a zinc coating (hot dipped, electroplated, or sprayed) on iron or steel articles that are coated after the shape is produced by casting, drawing, pressing, or other...
