本文主要叙述了等离子体喷涂Ni-Al和Fe-Al混合物涂层组分对阴极电位的影响。(一)选择了较为合理的喷涂工艺参数;射流功率为18—22KW;气体(Ar)流量55升/分;喷涂距离150毫米。(二)确定了涂层配方,在Ni-Al和Fe-Al的混合涂层中,铝含量在10—30%(重量)较为合宜。(三)测定了涂层的性能如下:气孔率15—40%;抗折强度340—1750公斤/厘米~2; This paper describes the plasma-sprayed Ni-Al and Fe-Al mixture on the cathode potential of the coating composition. (A) choose a more reasonable spraying process parameters; jet power of 18-22KW; gas (Ar) flow rate of 55 liters / min; spraying distance of 150 mm. (B) to determine the coating formulation, Ni-Al and Fe-Al mixed coating, the aluminum content of 10-30% (weight) is more appropriate. (C) Determination of the coating properties are as follows: Porosity 15-40%; flexural strength of 340-1750 kg / cm ~ 2;
