摘要：
Ti-6Al-4V (TC4) alloys were plasma carbonized at different temperatures (900, 950, and 1 000 degrees C) for duration of 3 h. Graphite rod was employed as carbon supplier to avoid the hydrogen brittleness which is ubiquitous in traditional gas carbonizing process. Two distinguished structures including a thin compound layer (carbides layer) and a thick layer with the mixed microstructure of TiC and the alpha-Ti in carburing layer were formed during carburizing. Furthermore, it was found that the microstructure and the properties of TC4 alloy were significantly related to the carbonizing temperature. The specimen plasma carbonized at 950 degrees C obtained maximum value both in the hardness and wear resistance.
