摘　　要：以煤矸石为主渗剂,采用粉末包埋法,在工业纯铜表面制备渗硅层。渗硅层组织结构分析表明,渗层中产生Cu4Si、Cu0.83Si0.17和Cu9Si等新相,主要由共析体(α+γ2)和α相组成,与基体结合紧密。耐磨性测试结果表明,渗硅层磨粒磨损性较纯铜提高2.68倍;冲击速度为200 r/min、300 r/min、400 r/min时,冲蚀磨损性较基体分别提高2.24倍、1.78倍和2.02倍。Siliconizing on copper with the method of powder pack comentation,which use gangue as main penetration agent. The microstrucaxre and organization of siliconizing layer analysis indicate that CuaSi, Cuo.83Si0.17 and CugSi are produced in layer, which is made up with （it＋q,2） and ct phase, and combine with matrix closely.The result of wear resistance indicates that abrasive wear resistance of siliconizing layer increase 2.68 times compared with copper. The erosion wear resistance of siliconizing layer increase 2.24 times, 1.78 times and 2.02 times respectively, when the erosion rate is 200 r/min, 300 r/min and 400 r/min.
