摘　　要：研究了电弧喷涂工艺参数对铝涂层孔隙率的影响,结果表明:在其它工艺参数不变的情况下,随着空气雾化压力的增加,铝涂层的孔隙率呈下降趋势;喷距在150～200 mm变化时,对孔隙率的影响不太明显,但喷距大于200 mm时,涂层的孔隙率明显增大;随着工作电压和工作电流的增加,涂层的孔隙率都是先减小后增大,并且工作电压在35～36 V之间,工作电流在170 A左右时,涂层的孔隙率达到最低。Influence of arc spraying parameters on the poriness of aluminum coating was studied,the result showed that： with the air atomization pressure increasing,the percent voids of aluminum coatings decreased when other process parameters unchanged;when spray distance is changed between 150 ~ 200 mm,the influence on poriness is not obvious while the distance is far than 200 mm,the coating factor of porosity significantly increased;with the operating voltage and operating current increasing,the coating poriness rates are decreasing and then increasing,and the minimum porosity of the coating was got when work voltage between the 35~36V,operating current at 170 A or so.
