This technical paper describes the research of a wear-resistant composite material (AW- 1), which was made of high-density polyethylene as base and then modified with addition of superhigh-polymer polyethylene, solid lubricator, toughening agent, and paddings as well, thus increasing wear resistance, impact toughness and tensile strength, reducing forming shrinkage, and saving costs.

The application of wear resistant materials in Wobei branch plant of Huaibei Coal Preparation Plant

Based on database technology and designing method of modularization,adopting production rules to express knowledge,database knowledge with a large amount of data of wear resistant materials,experience knowledge of expert and principle of materials selection had been established,the whole frame of the materials selection expert system of wear resistant materials had been designed.

To improve the valve using age,it is very important to select the wear resistant materials of flat gate valve.

In this paper the present situation of wear resistant materials industry in China was also introduced and some suggestions were given.

According to the papers in the conference,Recent development of wear resistant materials and wear technology,including wear resistant cast irons,wear resistant steels,wear resistant composites,wear resistant surface engineering,wear,standardization for wear resistant materials and castings,has been reviewed.
