The electroless nickel plating process utilizes an autocatalytic chemical reaction to deposit a reliable, repeatable coating of uniform thickness. This uniformity of deposit can, in some cases, eliminate the need for post-plate grinding.
Stress is a result of flexing, partial heating, machining or grinding of a heat treated component. These stresses, if not relieved, can be a factor in component failure.
THE ENGINEERING PROPERTIES OF ELECTRO LESS NICKEL COATINGS Electroless nickel is a term used to describe plating of a nickel-phosphorus coating onto a suitable substrate by chemical reduction. Unlike electroplated coatings, electroless nickel ... hard chrome coatings. This combination makes the coating
Khaled on Cr Replacement ANM-112N-01-02 Page 2 Abstract For decades, hard chrome (Cr) plating has been utilized in applications that require corrosion protection and/or wear resistance and also in the salvage industry, for rebuilding worn or ... Cr plating is a slow process; deposition rates of about 0.001 in. per hour are typical. Thus, during ...
The finishing industry is facing a greater challenge to reduce the environmental impact of its processes than ever before. Perhaps the paramount challenge is to replace chrome plating due to its negative environmental and health effects.

Grinding, Honing and Finishing Chrome Plating Hard chrome surfaces can be readily ground, honed, polished, lapped, or finished by various means. Because of its extreme hardness, however, proper stones, wheels, etc., must be used.
grinding before plating If a first class job is envisioned, then a little consideration must be given to the characteristics of the deposit before the grinder sets to work on the preparation of the parts.
Hard Chrome Plating is an electrolytic process utilizing a chromic acid based electrolyte; the part is made the cathode and, with the passage of a DC current via lead anodes, chromium metal builds on the component surface including stainless steels and cast irons.
Hard chrome impregnation is a proprietary chromium coating applied to metal to substantially increase wear and corrosion resistance. The hard chrome impregnation process provides lubricity, adherence properties and uniformity, which protect it from the eroding effects of friction, chemicals and weather.
Chromium is widely used in the metal finishing industry for both decorative and hard-chrome plating. Chromium plating has been carried out on a commercial basis since 1924. ... is significantly lower than that of a hexavalent plating solution—less than 3 oz/gal, versus 15–20 oz/gal for hexavalent solutions. ... corrosion to the early ...
In a chrome plating plant where poor exhaust resulted in excessively high concentration of chromium trioxide fumes, workers experienced symptoms of dizziness, headache, and weakness when working over the chromate tanks [Lieberman 1941].
Chrome plating (less commonly chromium plating), often referred to simply as chrome, is a technique of electroplating a thin layer of chromium onto a metal object. The chromed layer can be decorative, provide corrosion resistance, ease cleaning procedures, or increase surface hardness.
