TIC/7075铝基复合材料的磨损实验研究
Experimental Study of the Wear Resistance of TiC/7075 Al Matrix Composite
摘要
Abstract
The TiC reinforced 7075 Al matrix composites have been fabricated by melt in situ reaction spray deposition. The microstructures of spray-deposited alloys were studied using SEM and TEM.The dry sliding wear behavior of the alloys was investigated using a pin-on-disc machine under four loads, namely 8.9, 17.8, 26.7 and 35.6N. It has been found that the wear behavior of the alloys was dependent on the TiC content in microstructure and applied load. At lower load (8.9N), with increasing TiC content, the wear rate of the alloy was decreased. At higher loads (26.7, 35.6N), spray-deposited 7075 Al alloy exhibited superior wear resistance to the TiC/7075 composites.关键词
