Microstructure and Tribological Characteristics of AlSi-Al₂O₃
Joon-Won Min, Seung-Eul Yoo, Young-Jung Kim, Dong-Soo Suhr
Abstract
AlSi-Al₂O₃composite layer was prepared by plasma spray on steel substrate. The composite powder for plasma spray was prepared by simple mechanical blending. The wear resistance of the composite layers and matrix aluminum alloy were performed in terms of size distribution of ceramic particles. Friction coefficients of AlSi were decreased with incorporation of Al₂O₃. The tribological properties of coated layers were affected by the size of incorporated Al₂O₃particle. The reinforcement of Al₂O₃particle into aluminum alloy matrix decreased the friction coefficient as well as wear loss.
