本文首先介绍了在以铬、钼或钒进行合金化的钢上所形成的硼化物层的性质。所研究的性质有:化学成分、相成分、显微组织、厚度、硬度和粗糙度。文中给出的磨损试验结果是用不同的试验装置获得的。因此,其主要的磨损机理是可以判明的。这些结果表明:合金钢中的各种元素溶入硼化物层中,会 This article first describes the nature of boride layers formed on steel alloyed with chromium, molybdenum or vanadium. The properties studied are: chemical composition, phase composition, microstructure, thickness, hardness and roughness. The wear test results given in this paper were obtained using different test equipment. Therefore, its main wear mechanism is clear. These results indicate that the various elements in the alloy steel dissolve into the boride layer
