摘要：

Dry sliding wear behavior of in situ Al-Al4C3 Composite produced by mechanical alloying technique was examined. Mechanically alloyed Al-C powders were compacted at 650 MPa to produce the blanks with the size of phi 10 x 25 mm. These blanks were then sintered at 650 degrees C for 20 h and MMC samples with the density of 92% and the hardness of 314 Hv were produced. Dry sliding behavior of the produced Al-Al4C3 composite was examined by using pin-on-disk technique. In the case of low applying force, Fe based stable mechanical mixed layer was formed on the pin surface and which decreased the wear rate. However, high applied force resulted in the formation of mechanical deformed layer on the surface of samples which facilities the wear rate. (c) 2005 Elsevier Ltd. All rights reserved.
