Low friction MoS₂TiW coatings manufactured on X38CrMoV5‐1 steel using PVD method

Abstract

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. In this article the friction coefficients and the wear resistances of MoS 2 TiW protective coatings manufactured on X38CrMoV5-1 steel samples by using PVD technology are studied. The investigations based on tribometer tests which were carried out in different temperature conditions. The process of deposition of PVD coatings was realized by using multisource, hybrid factoryscale equipment of type URM 079. This equipment allows for deposition of coatings by the physical method. The tribological tests were performed using a precision high temperature tribometer under ambient and high temperature conditions with a steel and corundum balls as counter-samples. In this paper the results of these tribological tests are presented. It is shown that the measured friction coefficient of steel samples with PVD coatings is significantly lower than the friction coefficient of uncoated steel. It is also shown that X38CrMoV5-1 steel samples with manufactured MoS 2 TiW coatings are characterized by very low friction coefficient and high wear resistance.

Analysis of self-lubrication enhancement via PA66 strategies: Texturing and nano-reinforcement with ZrO2 and graphene

“…Owing to their composition [8] and industrial applications [9], new grease lubricants are continuously investigated to optimise the tribological performance. Hard coatings such as nanocomposites of silver containing carbon films (a-C:H/Ag) [10], Molibdenum dysulfide with mixture of titanium and tungsten (MoS2TiW) [11], (Zr,Ti)N deposited via physical vapour deposition (PVD) [12], and diamond films deposited via chemical vapour deposition (CVD) [13,14], as well as plasma spray techniques [15,16], are used to reduce heat generation. Some friction and wear phenomena are controlled by processes at the atomic or molecular scale, and others are controlled by processes at a scale of roughness of approximately 1-20 μm [17].…”
