中文摘要：

MoS2/Zr 合成电影被中等频率的磁控管在 cemented 碳化物 YT14 (WC+14%TiC+6%Co ) 上扔劈啪作响并且结合的多弧离子 plated 技术。合成电影性质上的否定偏爱电压的影响包括粘附力量，微坚硬，厚度和 tribological 性质被调查。结果证明合适的否定偏爱电压能显著地改善机械并且合成电影的 tribological 性质。电影性质上的否定偏爱电压的效果也被提出。最佳的否定偏爱电压是在这个实验下面的 200 V 条件。获得的合成电影是稠密的，粘附力量是大约 60 N，厚度是大约 2.4 m，并且微坚硬是大约 9.0 GPa。磨擦系数并且穿率 0.12 是并且结构和 composites 的电气化学的性质在订的 mesopo 主要取决于 SnO2 的装载数量的 2.1s 表演？

英文摘要：

MoS2/Zr composite films were deposited on the cemented carbide YT14 （WC＋14%TiC＋6%Co） by medium-frequency magnetron sputtered and coupled with multi-arc ion plated techniques.The influence of negative bias voltage on the composite film properties,including adhesion strength,micro-hardness,thickness and tribological properties were investigated.The results showed that proper negative bias voltage could significantly improve the mechanical and tribological properties of composite films.The effects of negative bias voltage on film properties were also put forward.The optimal negative bias voltage was -200 V under this experiment conditions.The obtained composite films were dense,the adhesion strength was about 60 N,the thickness was about 2.4 μm,and the micro-hardness was about 9.0 GPa.The friction coefficient and wear rate was 0.12 and 2.1×10-7 cm3/N·m respectively after 60 m sliding operation against hardened steel under a load of 20 N and a sliding speed of 200 rev·min-1.
