在销盘磨损试验机上，在载荷5-15 N、磨粒尺寸100-200 μm、滑动距离75 m条件下，研究了载荷和磨粒尺寸对Al 6082-5%SiC-5%Gr混杂复合材料两体磨料磨损系数的影响。在较低载荷和较大粒度下，铸造条件下，合金和混杂复合材料的磨损系数分别从0.771× 10 − 3降低到0.547×10− 3和0.73×10− 3降低到0.642×10− 3。但在较高载荷和磨粒尺寸下，磨损系数略有下降，铸态从0.48×10− 3降至0.46×10− 3，T6态从0.497×10− 3降至0.42×10− 3。磨损系数随载荷的增大而减小，随磨粒尺寸的增大而增大。对磨损表面进行了研究，以了解磨损机理。
The effect of applied load and grit size on two body abrasive wear coefficients of Al 6082–5%SiC–5%Gr hybrid composites was evaluated under pin on disc equipment at 5–15 N load, 100–200 µm grit size and 75 m sliding distance. At lower load and higher grit size, the wear coefficient decreases from 0.771×10−3to 0.547×10−3in cast condition; 0.73×10−3to 0.642×10−3in T6 condition when compared alloy to hybrid composite respectively. But at higher load and grit size, the wear coefficient marginally decreased from 0.48×10−3to 0.46×10−3in cast condition; 0.497×10−3to 0.42×10−3in T6 condition respectively. The wear coefficients decreased and increased with increase in load and grit size respectively. The investigation on worn surfaces was done to understand wear mechanism.
