Because of the dense alumina wear resistant ceramics with high mechanical properties, wear resistance, corrosion resistance and good large parts production capacity and is widely applied to different production of abrasion resistance parts.Studied by the ceramic protection company (Canada) with mud produced by the method of pouring and dry molding, alumina content is 1% ~ 8% (mass) of 9 9 mechanical properties and wear resistance of alumina ceramics;  Discuss the dense ceramic (such as alumina porcelain thoracic) damage mechanism;Some areas using alumina ceramics is discussed and analyzed.

All kinds of industrial process need to use strong wear resistant material to prevent wear and reduce wear environment contact equipment repair time, improve process performance.At the same time, due to reduced wear may occur in the process of pollution, and also improves the quality of the products.Especially the rapid flow of mud contains a hard particles, on equipment corrosion is more serious.Under the environment of strong erosion, such as acid, salt, reactive gas and high temperature conditions, equipment destroyed bad particularly serious.Traditionally, iron, steel and certain polymerization objects used in the wear parts of equipment, in general, wear resistant ceramic prices are relatively cheap, easy to manufacture and installation.
