Research and Application of Wear Resistant Metal
Abstract
Wear-resisting material is widely used in various fields of industrial production, and with the rapid development of science and technology and modern industry, due to material wear energy and material consumption to increase the economic losses caused by the quite striking. In recent years, the study of material wear and abrasion resistant materials, has attracted widespread attention at home and abroad. This article tells the story of our country at present the common high manganese steel, chromium wear-resistant cast iron, wear-resistant alloy steel, etc. Series wear resistant materials and all kinds of nonmetal material types and its properties, characteristics and preparation technology of all kinds of wear resistant material, working condition analysis of all kinds of wear resistant materials and wear mechanisms, is advantageous to the reasonable selection and application. Wear-resisting material demand situation both home and abroad and the analysis of existing problems of wear-resistant materials industry in our country, summarized the development of wear resistant material social economic benefits and promote the healthy development of the wear-resistant materials industry. And introduce the future development direction and trend of wear resistant material.
