Hard Chrome Plating
Hard chrome plating, also sometimes called chromium plating, is an electroplating process in which a layer of chromium is deposited onto a surface. This layer of chromium protects and extends the life of the part by improving wear resistance, reducing the coefficient of friction, and increasing mild corrosion resistance.
Understanding the Thin Dense Chrome Plating Process
For example, Electrolizing's thin dense chrome plating is applied much more slowly than traditional hard chrome plating, resulting in greater density and hardness exceeding 70 HRC vs. 65 HRC. While it is the less toxic and more environmentally of the two, Trivalent chrome has seen more success in decorative vs. industrial purposes.

Chrome Plating: What It Is and How It Works
Chrome plating is the process of applying chromium to another metal object. Chromium is the chemical element (Cr) and atomic number 24, and is an additive in steel. Chrome plating, or chromium plating, helps minimize wear and tear, as well as increase the lifespan of metal or engineering parts. By adding a layer of chrome to …
Chrome plating: benefits and applications
It requires nickel plating (up to two layers) prior to the application of the chromium plating. While it's called "chromium plating", the underlying layer of nickel is what provides this coating with practically all of its trademark reflectivity, smoothness, and much of its corrosion resistance. Nickel adheres extremely well to copper, so ...

Electroplating of chromium and Cr-carbide coating for carbon fiber
The other factor effect on the thickness of the deposited chromium layer is the plating time. Some experiments were carried out at different times of 15, 30, and 90 min and at constant current density of 0.27 A/cm 2 to obtain the suitable coating thickness. Fig. 3 shows the SEM of the deposited chromium layer at different plating time. It is clear …

Chrome Plating (Electroplating)
Chrome Plating (Electroplating) Decorative chrome plating is a multi-step electroplating process that applies chromium to a part to boost aesthetic appeal, prevent corrosion, and increase the hardness and durability of the surface. The parts are placed into large tanks containing a mixture of acids, organic chemicals, bases, metals, and water.
The Hull Cell: Key to Better Electroplating
Chromium plating baths and iron content in acid zinc are just two examples of applications. Thickness testers You'll often want to check electroplate thickness. A solution-drop test allows a corrosive solution to drop on a confined spot so that thickness can be determined by recording the time to remove the electroplate, exposing the basis …
