摘　　要：对合规运行直至失效的圆锥破碎机的动锥衬板表面进行了研究,依靠扫描电镜(SEM)及背散射电子(BSE)分析方法表征了衬板服役所伴生的氧化行为。试验结果表明,动锥衬板表层呈现出团簇状、片层状、堆积状等形态的氧化物区域,甚至在外层氧化物下存在着次表层氧化层。这些氧化物的存在加剧了服役过程中的损耗水平,探究其来源并阻止其产生过程,可以实现提高衬板在服役过程中的抗磨表现。The moving cone liner surface of the cone crusher failing during operation in compliance is explored.It s oxidation behavior is characterized by scanning electron microscopy(SEM)and backscatter electron(BSE)analysis.The experimental results show that the surface layer presents oxides in the form of clusters,lamellas,and stacks,and even a secondary surface oxide layer exists under the outer oxide.These oxides exacerbate the wear level during service process,and exploring their source and preventing their production process can improve the anti-wear performance of the liner during actual service process.
