“…Krishna et al [18] reported that well adherent rutile phase on titanium was formed with improved wear resistance and reduced friction coefficient. Different coatings using different surface treatment methods have been applied to titanium and its alloy to improve their friction properties [24][25][26]. Although some films especially MoS 2 and DLC gained the lower friction coefficient values to titanium surface, it can be said that anodizing is a more advantageous method compared with others if easy production and costing are taken into account.…”

“…Furthermore, the coatings should have a hard primary phase to provide wear resistance and load-bearing capability and a lubricating secondary phase to reduce the friction between the two contacting components if wear debris forms. Except for the diamond-like carbon(DLC) coatings, MoS 2 films have also been investigated [29]. Diamond and MoS 2 have different wear and lubrication mechanisms.…”

“…Generally, a complicated pretreatment should be carried out before MoS 2 coating. Wu [29] developed a simple two-step magnetron sputtering process to deposit Ti/MoS 2 . While MoS 2 provides the lubrication, the existence of Ti in the coating is thought to improve the adhesion of the film to the substrate.…”

Abstract-To overcome the the drawbacks of poor wear resisitance of titanium and its alloys, so far many efforts have been made to improve wear resistance and some techniques have been developed. Theses techniques can be classified into two categories: surface coating and surface cladding. Surface coatings generally include BN film, diamond-like carbon films and TiN films. These surface thin layers very significantly enhance the tribological properties although the some disadvantages still exist such as the small thickness, unstable composition, and poor adherence to substrate. The most applicable achievement is surface cladding. Surface cladding overcomes the drawbacks of surface coating. Not only the thickness of the surface composite layers can be controlled but the composition of the layer can be flexiblely choiced as well. Compositions of clad layer are diversified. The bonding strength between the surface clad layer and the substrate is very high. Among those, the laser beam cladding is a cutting edge and a promising method.

“…FF damage is closely related to the wear and fatigue resistance of the surface of the material, and it has been recognized that surface modification or coating can enhance the FFR of titanium alloys [5][6][7][8]. Shot peening (SP) is well known as a very effective method for improving FFR at room temperature [8][9].…”

An extensive study of the composition distribution, bonding strength, hardness, and wear resistance of a 0Cr18Ni9 film deposited on a Ti811 titanium alloy surface by ion beam enhanced deposition (IBED) is presented. Shot peening was introduced to post-treat the modified surface to synergistically improve the fretting fatigue resistance of the Ti811 alloy at 350°C. The results indicate that the 0Cr18Ni9 film with high density, small grain size, low void radio, and high bonding strength can be prepared using IBED. As a result, the hardness, wear resistance, and fretting fatigue resistance of the Ti811 alloy are increased to a remarkable extent. Compared with shot peening treatment or IBED 0Cr18Ni9 film alone, the Ti811 titanium alloy with an IBED 0Cr18Ni9 film combined with shot peening shows a higher fretting fatigue resistance at 350°C. This is due to the synergistic effect of the high wear resistance of the film surface and the residual compressive stress induced by shot peening.
