一、概述金属材料或零件在加热过程中的氧化和脱碳,不但大量损耗金属材料,更严重的是降低零件的热处理质量,从而影响零件的性能和使用寿命。防止氧化脱碳的方法很多,其中,涂层防护越来越被人们所重视。目前,国内外关于涂层防氧化脱碳的专利或配方虽然很多,但均属用多种原料混合配制,配制与涂覆都比较麻烦。另外,不少涂料的防护
First, an overview of metal materials or parts in the heating process of oxidation and decarburization, not only a large loss of metal materials, more serious is to reduce the quality of heat treatment parts, thus affecting the performance and service life of parts. There are many ways to prevent oxidation and decarbonization, of which, coating protection is more and more attention. At present, although there are many patents or formulations about the anti-oxidation and decarbonization of coatings both at home and abroad, they are all prepared from a variety of raw materials, and the preparation and coating are quite troublesome. In addition, many paint protection
