บทคัดย่อ

316L stainless steel (SS316L)/hexagonal boron nitride (h-BN) composites were prepared by powder metallurgy method. This was achieved by embedding hexagonal boron nitride powder, as a second phase, into the stainless matrix. The loading of the h-BN powder was varied at 0, 10, 15 and 20 vol. %, and the SS316L/h-BN powder compacts were then sintered in the H2 atmosphere for 1 h at the sintering temperatures of 1200ฐC and 1250ฐC. Density, hardness, wear behavior and microstructure of the sintered SS316L/h-BN composites were monitored. Experimental results indicated that a boride phase formed in the composite microstructure and its volume fraction appeared to increase at the sintering temperature of 1250ฐC. Dry sliding wear test was performed on a pin-on-disc test rig at the sliding speeds of 0.1 and 0.2 m/s and the varying loads of 1-5 N. The boride phase was found to affect the friction and wear behavior. It was found that wear resistance decreased with improvement of friction coefficient with h-BN addition. Increasing sliding speed also reduced the wear resistance whereas increasing sintering temperature improved the wear resistance and hardness. The specific wear rate of the SS316L/h-BN composites decreased with increasing applied load. Copyright ฉ (2012) by Asian-Australasian Association for Composite Materials (AACM).
