利用电镀技术在TA15合金表面上制备了纳米Ni-SiC复合涂层.研究了TA15合金基体及Ni-SiC复合涂层在室温和600℃时的磨损行为.结果表明,制备的Ni-SiC复合涂层致密,与基体结合较好,显微硬度要高于TA15合金的.室温时Ni-SiC复合涂层的平均摩擦系数比TA15合金基体的高,而在600℃时Ni-SiC复合涂层的平均摩擦系数要小于TA15合金的.600℃时Ni-SiC复合涂层的质量损失要低于TA15合金的,说明温度较高时Ni-SiC复合涂层具有较好的耐磨性.室温时TA15基体的磨损机制主要为黏着磨损、氧化磨损和摩擦磨损,而Ni-SiC复合涂层的磨损机制为摩擦磨损;600℃时TA15基体的主要磨损机制为黏着磨损、氧化磨损、摩擦磨损和疲劳磨损,而Ni-SiC复合涂层的磨损机制为摩擦磨损、疲劳磨损和氧化磨损.
