Abstract
A process is provided for producing wear-resistant boride layers on metal material surfaces. The process is characterized in that a boron halide selected from the group comprising boron trifluoride, boron tribromide, boron triiodide and their mixtures is mixed with hydrogen and optionally argon and/or nitrogen, in order to produce a reaction gas containing between 0.1 and 30 vol % boron halide. The resultant mixture is activated by a plasma discharge whereby boron is transferred from the plasma to the metal surface.
Claims6
A process for producing wear-resistant boride layers on metallic material surfaces, which comprises mixing at least one boron halide selected from the group consisting of boron trifluoride, boron tribromide and boron triiodide as boron source with hydrogen and possibly argon and/or nitrogen to generate a reaction gas containing from 1 to 35% by volume of boron halide and activating the resulting mixture by means of a plasma discharge so as to enable boron to be transferred from the plasma to the metal surface.
