Characterization of nanocomposite a-C:H/Ag thin films synthesized by a hybrid deposition process

Analysis of self-lubrication enhancement via PA66 strategies: Texturing and nano-reinforcement with ZrO2 and graphene

“…Owing to their composition [8] and industrial applications [9], new grease lubricants are continuously investigated to optimise the tribological performance. Hard coatings such as nanocomposites of silver containing carbon films (a-C:H/Ag) [10], Molibdenum dysulfide with mixture of titanium and tungsten (MoS2TiW) [11], (Zr,Ti)N deposited via physical vapour deposition (PVD) [12], and diamond films deposited via chemical vapour deposition (CVD) [13,14], as well as plasma spray techniques [15,16], are used to reduce heat generation. Some friction and wear phenomena are controlled by processes at the atomic or molecular scale, and others are controlled by processes at a scale of roughness of approximately 1-20 μm [17].…”
