Innovative Black Zinc Nickel Finish is a RoHS-compliant, cost-effective and sustainable plating alternative to Cadmium. There are also other ways to get black including zinc chromate. olive drab) and call it black zinc. We do all … Zinc Chromate Plating. The zinc layer acts as a sacrificial barrier, preventing damage from occurring to the underlying structure. The OP was black oxide vs zinc plated.

Black Zinc. It includes a layer of zinc applied to a parts surface followed by black chromate applied over the zinc. Black Chromate- a trivalent black chromate conversion coating for zinc that provides 120 hours to white corrosion, when used in conjunction with a sealer. You did not specify why you need a black-zinc coating, so I should point out to you that other types of black coatings are available. Black zinc plating is also a popular metal finish thanks to the striking appearance of the finished product. It is normally very thin and do not give measurable thickness to the overall coating. While the zinc iron clear … They all had a uniform coating of rust and would need to be totally refinished. High Salt Spray Clear - a high performance, trivalent passivate that can provide over 100 hours of corrosion resistance to white salts per ASTM B 117 to electroplated zinc. The most important purpose of zinc plating, in terms of functional characteristics, is to protect metals from corrosion effects or rust. That can be steel or alloy steel, stainless would be neither. Zinc iron plating was developed in the 1980’s in order to improve the appearance of black zinc plating. olive drab) and call it black zinc. Yellow Zinc — This type of zinc coating is commonly used in the automotive industry and offers an average level of protection against corrosion. Rack and Barrel Zinc Plating. Should the part require longer … The Black Zinc Plating Process Zinc plating involves an electrolytic application of zinc to metal by immersing clean steel parts into a zinc plating bath and applying electric current to it.


Others use formulations that are actually black plated. Nickel can be deposited soft or hard, dull or bright, depending upon process used and conditions employed in plating.
Black chromate films are typically very thin, around .000001” and contribute no measurable thickness to the overall coating. Others use formulations that are actually black plated. Our barrel and rack zinc plating lines provide a service that conforms to numerous plating specifications.

Zinc plating with black chromate offers better corrosion resistance and anti-galling characteristics than black oxide. In addition, black finishes can be applied on ferrous materials using black-oxide formulations at … Zinc plating is a soft, ductile, solderable corrosion resistance finish and it is used in order to protect the substrate. :] (OK stainless is a steel alloy but you don’t typically plate it) Personally I kinda like the black. Black zinc plating is a metal finish that is commonly used to provide the underlying element with additional protection from corrosion. The level of corrosion resistance of the latter will be somewhat lower than that of gold zinc – but better than clear passivate. Black Zinc Specialist – High volume computerized automatic processing up to 100,000 pounds of plating produced daily. Black Zinc. Founded in 1977, JMD Industries, Inc. specializes in Anodizing, Electroplating & other Electro-Chemical finishes on a variety of metals. Black zinc is zinc plating (say.0002" thick or more) followed by a black chromate conversion coating. Zinc Plating to Restore Plated Hardware by Al Truax (First printed in the Morgan Plus 4 Club's Format) When I examined the instruments on the 1954 Morgan that I'm restoring, I found the plated steel brackets that retain the speedometer, tachometer, and 4-1 gauges had lost nearly all the plating. It provides long-lasting corrosion resistance to exposed connector surfaces used on commercial aircraft and military planes, transportation vehicles and marine transports. Black Zinc is commonly specified for its dark appearance and protective properties. Black-nickel and chromium-plating processes are available.
