Hard Chrome Plating
Most people would not be very familiar with hard chrome plating. Hard chromium plating is chrome plating that has been applied as a fairly heavy coating ( usually measured in thousandths of an inch) for wear resistance, lubricity, oil retention, and other ' wear' purposes. Some examples would be hydraulic cylinder rods, rollers, piston rings, mold surfaces, thread guides, gun bores, etc. ' Hard chrome' is not really harder than other chrome plating, it is called hard chromium because it is thick enough that a hardness measurement can be performed on it and the chrome hardness can be measured, whereas thinner plating will break like an eggshell if a hardness test is conducted, so its hardness can' t really be measured directly.
Hard chrome plating is almost always applied to items that are made of steel, usually hardened steel. It is metallic in appearance but is not particularly reflective or decorative. Hard chrome plating is not a finish that you would want on a wheel or bumper.
There are variations even within hard chrome plating, with some of the coatings optimized to be especially porous for oil retention, etc.
Many shops who do hard chromium plating do no other kind of plating at all, because their business is designed to serve only engineered, wear-type, needs. If a shop says they do ' hard chrome only' , they have no service that most consumers would be interested in |
