- W4353032043 abstract "Abstract To improve the friction wear performance of the aluminum alloy scroll disc of the scroll compressor under dry friction conditions, the C-MoS2-PTFE-PEEK coating was prepared on the surface of the 4032 aluminum alloy substrate by thermal spraying. The friction and wear performance of C-MoS2-PTFE-PEEK coating under dry friction conditions was investigated via friction wear test, hardness test, coating adhesion scratch test, X-ray diffraction analysis test, morphological characteristics, element distribution test, And XPS photoelectron spectrometer. Moreover, the frictional wear performance of the C-MoS2-PTFE-PEEK coating was compared with that of the anodic oxide film of 4032 aluminum alloy and the Ni-plated coating of 4032 aluminum alloy. The results show that the hardness of C-MoS2-PTFE-PEEK coating is 102.8 HV0.2. The C-MoS2-PTFE-PEEK coating has good lubrication properties under dry friction conditions due to the synergistic effect of MoS2 and PTFE, which can effectively resist deformation and reduce the coefficient of friction. The average friction coefficient under 5N, 10N, and 15N loads are 0.12, 0.15, and 0.23, respectively. The Graphite can effectively form a solid lubricating film, improve the adhesion resistance of the composite, and cause the shallow and small wear mark of C-MoS2-PTFE-PEEK coating; The wear rate and friction coefficient of C-MoS2-PTFE-PEEK coating under different loads are lower than that of the anodic oxidation film of 4032 aluminum alloy and the Ni-plated coating of 4032 aluminum alloy, showing excellent anti-friction and wear resistance. The wear mechanism of C-MoS2-PTFE-PEEK coating under different loads is mainly fatigue wear, adhesive wear, and abrasive wear." @default.
