Paper Title:
The Compound Tribological Properties of Nano-Ceramic Lubricating Additives and Ni-W-P Alloy Coating
  Abstract

The major solving ways for the material wear are surface modification and lubrication. However, the application of only one solution can not achieve desirable effect. Ni–W–P alloy coating has high hardness and high wear resistance, and is an effect way of surface modification on the 45 steel. In the friction process, the nano ceramic lubricating additives deposited on the friction surface of Ni-W-P alloy coating so as to form a protective lubricating film, therefore realizing in-situ repair on the friction surface during operation. The nano ceramic particles achieve the antiwear and friction reducing effects by the micro polishing effect, the filling and repairing effects, ball bearing effect, multiphase microcrystal effect. Experiment results confirm that Ni-W-P alloy coating and nano ceramic lubricating additive have excellent synergistic effect, and form double protection for the metal substrate, e.g., the wear resistance of Ni-W-P alloy coating (with heat treatment and the oil with nano ceramic additives) has increased hundreds times than 45 steel as the metal substrate with basic oil, zero wear is achieved,which break through the bottleneck of previous separate research of the above-mentioned the two.
