Abstract

Tribological performances of Graphite/MoS₂ thermal sprayed composite coating on the surface of 9310 steel are researched experimentally. In doing so, the friction test of composite coating on the 9310 alloy steel disc surface is carried out, and influences of load and rotation speed on friction coefficient (COF) and wear rate (w) of the composite coating are further studied. The experimental results show that the coating transfer film is formed on the surface of 9310 alloy steel during the process of friction and wear, leading to the reduced COF and w of ball and disk. The load range of the composite coating for the stable anti-friction on the surface of 9310 alloy steel is 35–60 N. Meanwhile, the lowest values of COF and w at 60 N and 800 rpm are separately 0.09 and 1.93 × 10⁻⁸ mm³/(N∙ m). Furthermore, the limit high temperature of the composite coating with the function of lubrication and friction reduction is about 400 °C. The Graphite/MoS₂ composite coating on 9310 alloy steel in the present study shows better tribological performances than that on GCr15 steel. The above research provides a theoretical reference for the anti-friction technology of 9310 alloy steel and the application of Graphite/MoS₂ thermal sprayed composite coating in anti-friction engineering.

期刊介绍： Surface and Coatings Technology is an international archival journal publishing scientific papers on significant developments in surface and interface engineering to modify and improve the surface properties of materials for protection in demanding contact conditions or aggressive environments, or for enhanced functional performance. Contributions range from original scientific articles concerned with fundamental and applied aspects of research or direct applications of metallic, inorganic, organic and composite coatings, to invited reviews of current technology in specific areas. Papers submitted to this journal are expected to be in line with the following aspects in processes, and properties/performance: A. Processes: Physical and chemical vapour deposition techniques, thermal and plasma spraying, surface modification by directed energy techniques such as ion, electron and laser beams, thermo-chemical treatment, wet chemical and electrochemical processes such as plating, sol-gel coating, anodization, plasma electrolytic oxidation, etc., but excluding painting. B. Properties/performance: friction performance, wear resistance (e.g., abrasion, erosion, fretting, etc), corrosion and oxidation resistance, thermal protection, diffusion resistance, hydrophilicity/hydrophobicity, and properties relevant to smart materials behaviour and enhanced multifunctional performance for environmental, energy and medical applications, but excluding device aspects.
