摘要
The (TiB2-TiCxNy)/(Ni + W) composites were fabricated successfully by the method of combustion synthesis and hot press consolidation in the Ni-W-Ti-B4C-BN system. The effect of the content of W on the hardness, compression properties and abrasive wear behavior of the composites was investigated. The results indicate that with increasing W content from 0 to 8 wt.%, the average sizes of the TiB2 and TiCxNy particles decrease firstly and then keep almost constant, while the hardness and the compression strength increase firstly and then change a little. The abrasive wear resistance of the composites increases firstly and then decreases with the increase in the W content. (c) 2012 Elsevier Ltd. All rights reserved.
