Paper Title:
Study of Compatibility of the Nano Lubricating Additives with the Electroless Deposited Ni-W-P Coating
  Abstract

Tribological properties as well as antiwear and friction reduction mechanism of wear self repair nano-ceramic and nano-Cu lubricating additives are researched using ring-block abrasion testing machine and Energy Dispersive Spectrometer. Research results show great difference between friction reduction performances of the above two additives, because their friction reduction mechanism are different, the former is ball bearing effect and the latter is soft film shear effect. In terms of wear-resistance, as for 45 steel, under heavy load, the self repair rate to the worn surface with the nano additives is less than the wearing rate of the friction pair. An effective way to solve the problem is electroless deposited Ni-W-P alloy coating on the surface of the 45 steel. The Ni-W-P alloy coating has high hardness, high wear resistance, and has excellent compatibility with nano lubricating additive, the wear resistance of Ni-W-P alloy coating (with heat treatment and the oil with nano additives) has increases 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.
