“…A JSM-6390A scanning electron microscope (SEM) (JEOL, Ltd., Tokyo, Japan) was used to examine the coating structure and morphology. In addition, the coating composition and toughness were determined via energy dispersive spectroscopy (EDS) and by using a cyclic in-house press–press device [ 14 ], respectively.…”

The improvement and mechanism of the fatigue resistance of TC21 high-strength titanium alloy with a high velocity oxygen fuel (HVOF) sprayed WC-17Co coating was investigated. X-ray diffraction (XRD) and the corresponding stress measurement instrument, a surface roughness tester, a micro-hardness tester, and a scanning electron microscope (SEM) were used to determine the properties of the HVOF WC-17Co coating with or without shot peening. The fatigue behavior of the TC21 titanium alloy with or without the WC-17Co coating was determined by using a rotating bending fatigue testing machine. The results revealed that the polished HVOF sprayed WC-17Co coating had almost the same fatigue resistance as the TC21 titanium alloy substrate. This resulted from the polishing-induced residual surface compressive stress and a decrease in the stress concentration on the surface of the coating. Moderate-intensity shot peening of the polished WC-17Co coatings resulted in significant improvement of the fatigue resistance of the alloy. Furthermore, the fatigue life was substantially higher than that of the substrate, owing to the deep distribution of residual stress and high compressive stress induced by shot peening. The improved surface toughness of the coating can effectively delay the initiation of fatigue crack propagation.

“…Depending on the contact condition, relative displacement and stress magnitude at the interface during fretting wear, partial slip or full sliding condition (gross slip) can be observed in the contact, which relate to cracking and wear damage mode, respectively [30,41]. Figure 8a shows the typical fretting map (friction force-number of cyclesdisplacement amplitude, Q-D-N curve) for GLC films.…”

“…They found Cr-doped DLC films fractured quickly, while none-doped DLC films showed durability over 200,000 fretting cycles. Du and his co-workers [26] investigated the fretting wear and fretting fatigue behaviors of DLC and GLC films deposited on the Titanium alloy. They indicated the fretting wear and fatigue resistance of DLC films was better than that of GLC films due to its' more excellent bonding strength and toughness.…”

Graphite-like carbon (GLC) films with different thickness were deposited on 316L stainless steel using closed field unbalanced magnetron sputtering system to investigate the influence of film thickness on the microstructure, mechanical and tribological properties. The results showed that the surface of the deposited films exhibits granularlike morphology, the sp 2 content, surface roughness increase with the increase of film thickness, leading to the lower of hardness and higher of the internal stress. Both of the of friction curves obtained by nano-tribological tests and fretting wear experiments revealed a three-stage evolution tendency with the same wear mechanism for the first two stages. The intermediate thickness GLC film had the lowest specific wear rate, whilst the fretting fatigue life increased with film thickness.

WS x /a-C multilayer films with different layer thickness ratios and the modulation period of ~50 nm were prepared on monocrystalline silicon substrate by magnetron sputtering method. The morphology, microstructure and composition of the films were characterized by using scanning electron microscopy (SEM), X-ray diffractometry (XRD), energy dispersive X-ray spectroscopy (EDS) and Raman spectroscopy. The surface chemical states under different etching conditions were investigated by X-ray photoelectron spectroscopy (XPS) depth profile technique. The hardness, the adhesion to the substrate and the tribological properties of the films under various test environments were evaluated by means of nano-indentation, scratching tester and ball-on-disk tribometer. The results showed that a WS 2 phase with (101) preferential orientation was formed in WS x sublayer and the WC phase was not present at the WS x /a-C interface. The effects of L a-C /L WSx ratio on the microstructure of as-prepared films were negligible while the effects on the
