Abrasive wear of ceramic wear protection at ambient and high temperatures

Modelling Friction and Abrasive Wear of Elastomers

In order to properly model the friction and wear of elastomer materials, it is essential to understand some specific mechanical and tribological features. Mechanical characteristics of elastomer materials are different from those of metals and other relatively hard materials. Elastomers can bear large deformations, the stress-strain curves are non-linear, time and temperature dependent. When th...

Effect of Abrasive Size on Wear

Wear of denture teeth by use of metal plates. Part 2: Abrasive wear of posterior teeth.

An in vitro study was conducted to evaluate the abrasive wear resistance of high-strength denture teeth (HS teeth). Eight types of specimen were used in the experiments; 3 types of HS teeth, 3 types of conventional plastic denture teeth (PL teeth), porcelain teeth and metal teeth. Sliding-induced wear tests were conducted by sliding the samples on a metal plate. The abrasive wear resistance of ...

Sintered hydroxyapatite ceramic for wear studies.

A sintered hydroxyapatite (HAP) ceramic for use in wear studies was prepared from a commercial tricalcium phosphate. The sintered HAP had physical properties close to those of human enamel. The coefficient of friction and wear of the sintered HAP ceramic as characterized by tangential force, track width, and surface failure data, approximated those of human enamel.

In-vitro wear measurement of total knee replacement using tibial polyethylene inserts in combination with ceramic and metallic femoral components under abrasive three body wear conditions

INTRODUCTION: Due to increased life expectancy at human population the amount of osteoarthritis of the knee joint will increase. The total knee replacement (TKR) is often the only way to achieve analgesia, to establish the joint function and to correct joint deformation. TKR reached a high grade of quality and safety and has become an often used surgical procedure [1]. TKR most often fail due t...
