摘要:

采用正交设计方法和通过极差分析研究了电弧喷涂工艺参数对JCW-B涂层结合强度和耐磨性的影响.结果表明,影响涂层性能的工艺参数主要是电弧电流,其次是喷涂距离和雾化空气压力.涂层结合强度值随电弧电流的增大而增加.涂层中的孔隙率是影响涂层结合强度的主要因素,氧化物含量是影响涂层耐磨损性能的主要因素,采用适中的电弧电流可减少涂层中的孔隙率和氧化物数量,有利于提高涂层的结合强度和耐磨性,获得具有良好综合性能的涂层.

Abstract:

The influence of arc spraying parameters on the adhesive strength and wear-resistance of JCW-B coating was studied by orthogonal design test and extreme analysis. The results showed that the main parameters influencing the coating properties are the arc current, spraying distance and air pressure. The adhesive strength increased along with the arc current. The porosity in the coating was the main reason influencing the adhesive strength of coating. The oxide was the main reason influencing its wear-resistance. Selecting a moderate arc current can decrease the porosity and oxide, and increase the adhesive strength and wear-resistance of the coating.
