原位AA5052/ZrB2复合材料的磨损研究表明，累积磨损量与滑动距离呈线性关系，摩擦系数呈波动趋势。磨损率和摩擦系数随滑动速度和载荷的增加而不断增加，在较高的数值下呈现由轻到重的过渡。ZrB2的添加量也会影响材料的磨损和摩擦性能。磨损表面研究和能谱分析与磨损和摩擦结果一致。形貌和力学性能也与磨损和摩擦有关。这些复合材料在制动鼓/转子、气缸套、连杆、缸体和活塞等领域具有潜在的应用前景。(C) 2016 Elsevier Ltd.版权所有。
Wear studies of insitu AA5052/ZrB2 composites show a linear relationship between cumulative wear and sliding distance, whereas, coefficient of friction has fluctuating tendency. Wear rate and coefficient of friction continuously increase with sliding velocity and load showing mild to severe transition at higher values. Amount of ZrB2 also affects the wear and friction behaviour. The worn surface study and EDS analysis are in agreement with wear and friction results. Morphology and mechanical properties have also been correlated with wear and friction. These composites could be potential candidate in applications like brake drums/rotors, cylinder liners, connecting rods, cylinder blocks and pistons. (C) 2016 Elsevier Ltd. All rights reserved.
