... the growth of the passivation film and the mechanical removal of such film were the driving factors for the tribocorrosion process. Furthermore, when the steel was coated with the tungsten oxynitride film, we found that the surface presented a better resistance to wear, corrosion, and tribocorrosion...

... is performed to target the effects of surface roughness and the rotation of transported particles. The two-phase flow is modeled using the Euler-Lagrange approach. The near-wall turbulence model, K-ω, governs the stochastic flow. The number of particles injected in terms of “number of tries” plays...

... the morphologies and cross sections of wear scar corresponding to different oil samples. For the worn surface lubricated by the oil sample containing MSH, obvious grooves can be found in the sliding direction, which indicates that wear is serious. Compared with MSH, the smoother worn surface corresponding to MSHH...

... particles break away three-body abrasive wear is produced. As shown in Table 1 , Sample D and Sample E have the same electrical plating process, but Sample E has a thicker Cu coating than Sample D, which is why Sample E has a rougher surface profile. This roughening was also found by Lin and Lin [ 11...
