镁合金热室压铸机压射室材料摩擦磨损机制研究

摘要

according to the working characters between plunger and sleeve ofhot die casting machine for magnesium alloy, their osculant mechanism is discussed and the research status quo of wear, erosion and their cooperation each other is also described so as to improve the life time of the sleeve material.%针对镁合金热室压铸机压射室和冲头的工况条件和工作特点，阐述了两者之间的接触机制，分析了腐蚀、磨损及腐蚀与磨损的协同作用的研究现状，为改善和提高压射室材料的使用寿命提供依据。
