【摘要】 在分析了各种传统金属基复合材料制备方法的基础上,提出了金属基复合材料压力下浸渗-挤压铸造致密法制备新工艺。利用该工艺制备出Al2O3sf.SiCp/铝基复合材料,同时以负重轮为典型制件,利用这项新工艺实现了复合材料耐磨圈与本体挤压铸造的一体化成形。对制件观察和性能测试表明,该工艺制备的复合材料界面结合良好、组织致密、性能优异。更多还原

【Abstract】 A new technology for metal matrix composites——liquid infiltration-forging densification under pressure was proposed based on the analysis of some traditional methods.And the Al2O3f·SiCp/Al composites were prepared by the methods.Microstructure and performance testing show that interface bonding of the composites exhibits metallurgical bonding with compact structure and excellent properties.The typical parts——loading wheel was produced by the method,realizing the liquid forging integral forming between wear-resistant composites ring and main body.更多还原
