Estimation on Wear Damage Process of Poly-Vinyl-Alcohol Gel Surface with Particle Analysis

Poly-vinyl-alcohol (PVA) hydrogel shows unique characteristics, especially self lubrication function and future application is expected such as components in artificial joints. One of the problems for future application is the lack of damage process information on this material. PVA-gel shows strong...
