Loads carrying capacity map for the surface texture design of SiC thrust bearing sliding in water
TL;DR: In this paper, an optimum surface texture pattern was selected to improve the load carrying capacity of SiC bearing working in water, where micro-pits, evenly distributed in a square array, were selected as the texture pattern, and formed on one of the contact surfaces by reactive ion etching.
Journal ArticleDOI
An experimental and theoretical investigation of ploughing, cutting and wedge formation during abrasive wear
Kazuo Hokkirigawa,Koji Kato +1 more
TL;DR: In this article, the degree of penetration, D p, was introduced as an index to describe the severity of contact and a wear mode diagram was developed to show the possible region for each wear mode of cutting, wedge forming or ploughing with parameters of D p and the shearing strength at the contact interface.
Journal ArticleDOI
Wear in relation to friction — a review
TL;DR: In this paper, the coefficients of friction and wear are not material properties but two kinds of responses of a tribo-system and they are always reasonably related with each other when the necessary functions of the tribo system are well considered.
Journal ArticleDOI
Formation of tribochemical layer of ceramics sliding in water and its role for low friction
Junguo Xu,Koji Kato +1 more
TL;DR: The formation of a tribochemical layer on silicon nitride sliding in water is studied in this article, where an additive that accelerates the formation of colloidal silica makes the running-in distance shorter.
Journal ArticleDOI
The effect of laser texturing of SiC surface on the critical load for the transition of water lubrication mode from hydrodynamic to mixed
TL;DR: In this paper, the effect of the pore area ratio on friction coefficient and the critical load for the transition from hydrodynamic lubrication to mixed lubrication was discussed and discussed.
