Given that human tooth enamel contains 92–96wt% inorganic substances, it is often considered as a biological ceramic material. However, recently a few studies have indicated that the unique composition and microstructure of enamel result in its nanomechanical performance similar to that of metal materials. To extend the understanding of enamel wear mechanism, the sliding wear behavior of human tooth...
Lubrication is the primary function of saliva in the mouth, which is closely associated with the adsorbed salivary proteins. Previous studies have suggested that the amount of adsorbed salivary proteins on the surfaces of human teeth depends on adsorption time. The objective of this study is to investigate the effect of adsorption time on the lubricating performance of human whole saliva. In this...
In order to understand the tribological properties of ceramic coatings in some fluid environments, the friction and wear behaviours of plasma-sprayed Cr 3 C 2 NiCr against TiO 2 coating under water- and ethanol-lubricated sliding were investigated with a block-on-ring arrangement. The tracks and debris were carefully collected and examined and analysed employing scanning electron...
Wear of plasma-sprayed TiO 2 coating against stainless steel was tested with a block-on-ring arrangement at different loads and sliding speeds. It was found that wear mass loss of TiO 2 coating increased with increase in loads but decreased with increase in sliding speeds. The mechanism was explained in terms of grinding wear, adhesive wear, micromechanical delamination wear, plastic...
