摘要：
The chemical state and tribological properties of tempered and annealed steels (95MnCrW5 and 30CrMoV12) implanted with C+Ti has been studied by using the Auger sputtering depth profile and the ball on disk method to determine the wear parameters. The sample hardness was measured by the Vickers method. Friction coefficients are reduced by a factor of 0.8 for samples of steel 95MnCrW5 and by a factor of 0.4 for samples of 30CrMoV12 steel. The implanted 95MnCrW5 samples show a phase of mixed amorphous carbon and carbides. The amorphous carbon forms a layer on the surface, while a mixture of TiC and amorphous carbon is really implanted beneath the surface. Molecules of the residual gas containing C are the origin of either the amorphous carbon layer or the contamination of the implanted layer.
