Electroless Ni-P-PTFE Composite Coatings on Titanium Alloy and Their Tribological Properties

Abstract:

In this study, it was the first attempt to fabricate Ni-P-PTFE composite coatings on titanium alloy (manufactured through electroless composite plating). The effects of suspended PTFE concentration, temperature and surfactant concentration in the plating solution on the PTFE content in the resulting coatings were investigated. In addition, the friction and wear properties of the samples were analyzed. The results showed that co-deposition of Ni-P and PTFE can obviously decrease the friction coefficient of the coatings, reduce wear and improve lubricating property of the coatings.
