摘要
以得到较高质量的涂层为目的,从喷涂工艺入手,较详细地讨论了几个主要参数对涂层沉积效率的影响,得到了最佳的喷涂参数。实验结果表明:按照这些喷涂参数进行等离子喷涂加工,所得到的涂层具有较优的质量,其与基体的结合强度可达1.5~2.5kg/mm2,气孔率为6%~9%。
The main purpose of this paper is to discuss how to obtain the high quality of plasma^sprayed coatings. Experimental studies were performed on the deposit efficiency of Fe-Cr-B-Si powder to set optimum process parameter. The experimental results show that the high quality of the deposit of Fe-Cr-B-Si powder is gotten according to the optimum process parameters, adhesion strength of the deposit reaches 1.5--2.5 kg/mm2, and the rate of porosity is reduced by 6%-9%.
