Basic properties of the suggested phenomenological model of tribocorrosion wear are considered. Using a friction pair austenitic stainless steel-ceramic in acid electrolytes as an example, a good agreement between predicted data and experimental evidence was obtained.

A study has been carried out to investigate the influence of soot contaminated automotive lubricants in the wear process of a simulated engine valve train contact. Previous research on this topic has been mainly performed from a chemical point of view in fundamental studies, with insufficient relevance to real engine conditions i.e. load and geometry. This study investigates the conditions unde...

The popularity of composite materials usage is increasing due to its superior strength characters racing the traditional materials in strength to weight ratio. The developments of new materials are on the anvil and are growing day by day. In this work, two-body abrasive wear test with different loads and abrading distances were performed at room temperature by using a pin on a disk apparatus to...

Nowadays steel balls wear is a major problem in mineral processing industries and forms a significant part of the grinding cost. Different factors are effective on balls wear. It is needed to find models which are capable to estimate wear rate from these factors. In this paper a back propagation neural network (BPNN) and multiple linear regression (MLR) method have been used to predict wear rat...

The optoelectronic properties of gallium nitride (GaN) have been well studied for decades, with results being translated to applications in solid state lighting and lasers, thermoelectricity, solar cells, power electronics, etc. However, the mechanical and tribological properties of GaN have been studied and understood far less than its optoelectronic properties. Our research aims to explore th...

A new Stratified Approach For Enhanced Reliability (SAFER) pre-clinical simulation testing of joint prostheses has been described in a preceding paper in this volume. The application of SAFER in vitro simulation and testing to metal-on-metal bearings is described in this review paper. The review aims to provide further understanding of the reasons for, and causes of, increased wear in metal-on-...

We conducted a systematic review and meta-analysis of randomised controlled trials comparing cross-linked with conventional polyethylene liners for total hip replacement in order to determine whether these liners reduce rates of wear, radiological evidence of osteolysis and the need for revision. The MEDLINE, EMBASE and COCHRANE databases were searched from their inception to May 2010 for all t...

Glass fiber reinforced plastic composite materials are finding increased applications due to their excellent properties. Fiber reinforced plastic (FRP) composite materials comprise soft matrix and fiber elements. This article presents the tribological aspects of glass fiber reinforced plastic composites. The wear test is carried out for FRP in a pin-on-roller wear tester. The wear rate obtained...
