Surface texturing for adaptive solid lubrication

Friction and Wear Properties of MoS2-Overcoated Laser Surface-Textured Silver-Containing Nickel-Based Alloy at Elevated Temperatures

“…7b). The laser surface-textured dimples act as storage areas of solid lubrication from room temperature to 400°C, which favors the formation of lubricating film on the frictional surface [20]. After the lubricants on the surface are oxidized, solid lubricants released from the dimples and fresh lubricants are released on the frictional surface, which is helpful for the reduction of friction at high temperature.…”

“…Compared with the untextured surface, the wear life of the MoS 2 film cover on the textured surface was extended by more than one grade of magnitude [19]. Basnyat et al [20] studied the Mo/MoS 2 /Ag lubricant on the textured TiAlCN hard layer and found that the friction coefficient and wear rate at temperatures from 25 to 570°C were significantly decreased.…”

Plasma assisted parts' manufacturing: sintering and surface texturing - part II - influence of inter-cathode distance and gas pressure

“…The results presented here indicate that the hollow cathode discharge could be applied to develop a new green technology for surface texturing, becoming a new technique to improve surface properties such as roughness and morphology. These properties are significant parameters for many applications directly related to the coatings adhesion, tribological performance, and others, according to Gupta et al (2007), Basnyat et al (2008), and Krupka et al (2008).…”
