for thirty years in industrial applications, have still been studied extensively today due to their relatively high hardness and wear resistance [1-2]. However, at temperatures above 500 °C they start... crystallite and amorphous Si3N4 tissue phase with high cohesive energy should be responsible for the hardness enhancement. The ratio of Si3N4 tissue phase to the specific interface of the TiN......

of alloys is considered to be based on their hardness (W=k(LP/H)) [22]. The high hardness can improve the wear resistance of materials during wear process. The specimen CB0 has low hardness as compared..., the hardness of specimens containing B element decreases, and the oxides content is low or the rate of oxides formation is not enough to provide lubricating effect for specimens, resulting in the high wear......
