Abstract
A method of depositing hard, wear-resistant coatings on workpieces and utility articles by evaporating a metal such as titanium in a reactive atmosphere. To make the coating hard as far as possible, wear resistant, and less susceptible to oxidation, the deposition is effected in an atmosphere containing nitrogen, oxygen and carbon, with the atomic number proportion of O to C ranging between 0.5 and 1.5. An evaporation by means of a low voltage arc discharge and the use of CO as the residual gas atmosphere are particularly advisable.
