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.
