Abstract
A process for reducing oxygen content in thermally sprayed metal coatings comprises the following steps. A metal powder is provided. The metal powder has a particle size in the range of from about 10 .mu.m to about 500 .mu.m. Carbon is adhered and coated to the metal powder to form a carbon coated metal powder. The carbon is present in the range of from about 0.1% to about 2.0% by weight of the carbon coated metal powder. The carbon coated metal powder is thermally sprayed onto a substrate and a metal coating is deposited on the substrate. The metal coating has a lower oxygen content compared to the oxygen content of the carbon coated metal powder.
