摘要
研究了电流密度、镀液温度、pH值和PTFE等对电沉积RE Ni W P SiC PTFE复合镀层性能的影响。结果表明 ,镀态下镀层的硬度在 42 0～ 5 5 0Hv之间 ,当镀液中PTFE浓度为 2 5ml/L时 ,磨损量最小 ,但镀层的耐蚀性却最差 ;而当镀液中PTFE浓度为 30ml/L时 。
The effect of process conditions, such as current density, bath temperature, pH value, PTFE, etc, on the properties of electrodeposited RE Ni W P SiC PTFE composite coatings is studied. The results show that the hardness of the composite coating is between 420 and 550 Hv as deposited; the abrasion of the composite coatings is the least when PTFE concentration in the bath is 25 ml/L, but the corrosion resistance is the worst; and the comprehensive properties of the deposit are the best when PTFE concentration in the bath is 30 ml/L on the basis of plating conditions.
