how to rechromize chrome plating
There are two basic types of chrome plating: hard chrome plating and thin dense chrome plating. Hard chrome plating leaves a layer of chrome from 0.0008 to 0.0050 in. (from 0.020 to 0.127 mm) thick on the surface of the metal. In contrast, thin dense chrome plating has a thickness from 0.0002 to 0.0006 inch (0.005 to 0.015 mm).

Hard Chrome Extreme hardness, resistance to wear, corrosion protection, improved lubricating propertiesThe primary difference between decorative chrome and hard chrome plating is the thickness of the chrome plating on the final product. Decorative chrome plating is thinner than hard chrome and is primarily for aesthetic appeal and as a protective coating. . Measuring between 68 and 72 HRC, hard chrome plating can withstand demanding industrial .The required thickness of the chrome layer is decisive for the subsequent chemical and mechanical stress. The following layer thicknesses are applied: A layer thickness of 5 to 15 μm is applied in case of light wear. In addition, such a layer thickness serves to reduce friction. Hard chrome coatings of 15 to 30 μm protect against moderate wear.
Similarly to Average thicknesses, it is at the plater’s discretion where to measure the product unless the measuring location is indicated on the print. If the range is ≤ 0.00015” (150uin) it is treated as a single average with the mid point of the range being the target average and the definition of average thickness above applies.This article explains the step-by-step hydraulic cylinder rod hard chrome plating process and why it is so important for hydraulic cylinder repair.

It is very hard, measuring between 66 to 70 HRC. Hard chrome tends to be thicker than the decorative treatment, typically ranging from 0.075 to 0.25 millimetres (0.0030 to 0.0098 in), but thinner and thicker layers are not uncommon. Surface defects and roughness are amplified, because hard chrome does not have a leveling effect.
