摘要
复合材料因其高强度重量比，最适合许多工程应用。金属基复合材料因其卓越的机械性能和制备经济性而备受关注。本研究采用搅拌铸造法制备含有不同浓度 SiC 颗粒的铝 6065。扫描电子显微镜（SEM）用于研究颗粒含量（8 至 12 wt%）、负载变量和镍铬涂层厚度（100 和 200 微米）对复合材料抗划伤性的影响。划痕试验还用于检测铝基复合材料的摩擦系数和划痕形态。结果发现，与基体材料中较低的颗粒浓度相比，颗粒含量越高，抗划痕性能越好。
AN INVESTIGATION ON THE EFFECT OF NI-CR COATING THICKNESS ON THE SCRATCH RESISTANCE OF PARTICLE-
Composite materials are best suited for many engineering applications due to their high strength-to-weight ratio. Metal matrix composites have drawn attention due to their superior mechanical qualities and economics in preparation. This study uses stir casting to prepare aluminum 6065 with SiC particles in varied concentrations. Scanning electron microscopy (SEM) was used to examine the effects of particle content (8 to 12 wt%), loading variables, and Ni-Cr coating thickness (100 and 200 microns) on the scratch resistance of the composites. Scratch tests were also used to examine the friction coefficient and scratch morphology of the aluminum matrix composites. When compared to lower particle concentrations in the matrix material, it has been found that more significant particle content provides more excellent scratch resistance.
