| More than 40,000 well-preserved bronze weapons were found with a chromium coating
, a technique that was thought to only have been discovered in 1937!
The visible slight characteristics of plastic deformation are found, which may be attributed to the chromium coating
of T10 steel in Figure 3(a).

Deposition of wear resistant chromium plating causes decrease in the fatigue strength of the base material though chromium coating
had excellent corrosion resistance.
As a matter of fact, top piston ring of the engines is very often covered with a hard chromium coating
to ensure its longevity; this coating is obtained via an electrolytic process which requires the use of hexavalent chromium ions.
The chromium coating
effectively reduces friction between the paste and blade, thus improving filling of small apertures and resulting in a higher volume of paste deposited.
Schuh points out that the chromium coating
industry is a multibillion-dollar industry, and the problems associated with hexavalent chromium account for a significant percentage of the process cost.
The coating is a combination of Armoloy's TDC chromium coating
with the addition of spherical diamond particles.
