    摘要:

    為獲得性能良好的鎳鐵鎢合金鍍層,研究了鍍液pH 值、溫度、電流密度、穩(wěn)定劑抗壞血酸濃度對鎳鐵鎢合金鍍層成分和鍍層沉積速率、顯微硬度的影響。結(jié)果表明: 鍍液pH 值對鍍層W含量和鍍層沉積速率影響較大；鍍液溫度對鍍層沉積速率、鍍層成分和鍍層硬度影響均較大；隨抗壞血酸濃度增加,鍍層沉積速率逐漸降低,鍍層表面形貌更加粗糙。在鍍液pH = 4,溫度60 ℃,電流密度4 A/dm2,抗壞血酸濃度3 g /L 時,鍍層沉積速率和鍍層的顯微硬度較高,表面光亮致密,耐蝕性好。

    Abstract:

    In order to obtain NiFeW alloy coating with good performance, we studied the influence of pH value, temperature, current density, and the concentration of ascorbic acid stabilizer on the composition, deposition rate, and microhardness of NiFeW alloy coating. The results show that 1) the pH value of plating bath largely influences the concentration of W and the deposition rate of coating; 2) the temperature of plating bath largely influences the deposition rate, composition, and microhardness of coating; and 3) upon increasing the concentration of ascorbic acid, the deposition rate of coating decreases whereas the surface morphology of coating becomes more rough. With a pH of plating bath equal to 4, a temperature of 60 ℃, a current density of 4 A/dm2, and an ascorbic-acid concentration of 3 g/L, both the deposition rate and the hardness of the coating are high. In addition, both the surface quality and the corrosion resistance of the coating are good.
