  • Process for producing wear-resistant boride layers on metallic material surfaces
    Patent number: 6306225
    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.
