ABSTRACT:
A ceramic chromium oxide coating produced by applying a conventional chromium oxide coating to a substrate and wholly or partly fusing the conventional chromium oxide coating by subjecting the chromium oxide coating to laser irradiation. The chromium oxide coating can optionally contain silica and/or alumina and less than 1 percent of metal.
The chromium oxide coating can be employed for the internal and/or external protection of components in equipment for production and transport of oil and gas under water.
