| 目的 研究摩擦速度、载荷及加热温度对Ni-P/Ti/DLC多层膜摩擦磨损性能的影响。方法 用化学镀镍磷工艺在模具钢基体表面镀上Ni-P层作切削层，采用过滤阴极真空电弧（FCVA）技术分别沉积Ti过渡层和DLC保护层。通过摩擦磨损实验，评价该多层膜的摩擦磨损性能。利用纳米压痕测试和拉曼光谱检测，研究该多层膜在不同加热温度下的硬度、弹性模量和结构成分。利用扫描电镜及表面轮廓仪分别对该多层膜的磨痕形貌和横截面轮廓进行分析。结果 随着摩擦速度的增大，Ni-P/Ti/DLC多层膜的摩擦系数呈下降趋势，磨损率和磨损体积呈先减后增的趋势。不同载荷下的摩擦系数变化幅度较小，磨损率和磨损体积随着载荷的增大呈增加的趋势。随着加热温度的升高，摩擦系数呈下降趋势，磨损率和磨损体积呈先增后减的趋势。此外，随着加热温度的升高，多层膜表层DLC膜中石墨相逐渐增多，硬度和弹性模量随之呈先增后减的趋势。结论 较高摩擦速度下，多层膜表层DLC膜石墨化趋势增强，摩擦系数变化幅度较大，且表面磨痕宽度和深度显著增加，磨损加剧。多层膜中软质的Ti金属层和硬质的DLC层，能有效提高多层膜在高载荷下的摩擦磨损性能。随着加热温度的升高，多层膜表层DLC膜中石墨相逐渐增多，摩擦过程更易生成转移膜。 |

| The work aims to study effects of sliding speed, normal load and heating temperature on friction and wear properties of Ni-P/Ti/DLC multilayer films. Ni-P layer was plated on die steel substrates by adopting electroless nickel-phosphate plating process, and Ti transition layer and DLC protective layer were deposited by adopting filtered cathodic vacuum arc technology individually. Friction and wear properties of the multilayer films were evaluated in friction and wear experiments. Hardness, elastic modulus and composition of the multilayer films at different heating temperature were characterized based upon nanoindentation test and Raman spectrum detection. Wear track morphology and cross-sectional profile of the multilayer films were also analyzed with scanning electron microscope (SEM) and surface profile instrument. As the sliding speed increased, friction coefficient of the multilayer films decreased, and wear rate and volume first reduced and then increased. Friction coefficient of multilayer films changed slightly at different normal loads, and wear rate and volume increased as normal load increased. As the heating temperature increased, the friction coefficient of multilayer films decreased, and wear rate and volume first increased and then decreased. In addition, at higher heating temperature, graphite phase gradually increased on DLC layer of the multilayer films, hardness and elastic modulus tended to first increase and then decrease. At higher slide speed, graphitization trend of the DLC layer intensifies, friction coefficient changes greatly, width and depth of wear tracks increase greatly, and wear is worse. Soft Ti metal layer and hard DLC layer in multilayer films can effectively improve friction and wear properties at high load. As heating temperature increases, graphite phase gradually increases in DLC layer, and transfer film is easier to be generated in friction process. |
