Abstract: Inspired by the excellent water lubrication properties of Al2O3, two methods are used to fabricate Ni/Al2O3 composite coatings for water lubrication. One is the conventional composite electroplating technique (one-step ...

Abstract: Fretting wear refers to the damage phenomenon experienced by the mechanical components undergoing micro-amplitude relative slip at their contact region due to vibration. Titanium alloys find their extensive application in ...

Abstract: Magnetic fluids (MFs) are a kind of magnetically manipulated colloid, which may serve as an active lubricant. These fluids can be retained at the desired locations, by the application of an appropriately designed external ...

Abstract: Thermocapillary migration is an interfacial phenomenon that describes liquid flow on a nonisothermal surface from warm to cold regions in the absence of external forces. It is a typical lubricant loss mechanism in tribosystems. ...

Abstract: In this work, the dynamic process of oil droplets impacting and migrating on structured surfaces with imposed thermal gradients was investigated. It was observed that on an isothermal smooth surface, a lubricant droplet ...
