Alacote Nickel Chrome Plating
Nickel Chrome Plating is suggested for corrosive environments, such as seawater or chemical environments. One particular application is for seawater based hydraulic cylinders, used on cranes & other applications.
Hard industrial chrome is a porous coating which contains microscopic fissures due to the way in which chrome is applied to the base metal. While chrome of 0.005″ -0.010″ thick will provide optimum protection against wear, over time, a corrosive environment will break down the chrome before its typical wear life has been realized. It does this by attacking the base metal under the chrome and the subsequent rust causes a break in the adhesion of the chrome.
The way to combat this is to apply a thin layer, less than 0.001″ up to 0.002″ thick, of insomuch Nickel before applying the chrome. This layer will provide the corrosion resistance needed to allow the chrome to realize its full wear resistant life.
Whether we apply Chrome, or Nickel-Chrome, we can achieve a wide range of surface finishes to meet customer needs.
Polish finishes range from 1-2 RMS up to 32 RMS. Typical
Matte finishes (blasted or nodular) can range from 30 RMS up to 200 RMS.

Lower RMS provides higher friction between the roller and the material passing over it.
Grinding & Finishing
Before and after coating, your roller and cylinder parts can be ground and polished (in-house) to a low profile finish.
