摘要
The wear resistance of boron nitride films was studied. The films of 1 mum thickness were prepared on the surface of a cutting tool by simultaneous nitrogen ion irradiation and vapor deposition of boron; the Vickers hardness of the films was between 3000 and 5000 kg/mm2. The test was performed by the cutting of steel. On the tool deposited directly, the wear of the surface is large and this could not be improved greatly. However, the tools prepared after nitridation of the surface layer by ion implantation and the one with another nitride layer in the interface showed decreasing wear, and the wear of the tool with an interlayer of silicon nitride could be decreased to about 15%. As a result, it became clear that boron nitride could be effectively used as a highly hard film by the optimization of the interface between the film and the matrix.
