【摘要】 本文介绍了化学镀以及化学镀反应的机理，总结了近十年来用化学镀方法施镀Ni基、Co基、Cu基、Fe基合金的研究进展。首次利用化学镀的方法在铜基片上沉积了非晶态Fe-Zn合金。通过对其沉积工艺的研究，得到了施镀Fe-Zn合金的最佳配方：FeSO4·7H2O 8g／l，ZnSO4·7H2O 7g／l，C4H4O6KNa·4H2O 65g／l，NaH2PO2·H2O 8g／l，NaOH 35g／l，H3BO3 1g／l，糊精1g／l，施镀温度 55℃，施镀时间：20min．并且研究了镀层的成分、形貌及结构。研究了Fe-Zn镀层在10％的氢氧化钠和3.5％的氯化钠溶液中的耐腐蚀性能，结果表明，化学镀Fe-Zn镀层的耐腐蚀性能比其他Fe基化学镀层的耐腐蚀性要好。随后研究了镀层的显微硬度随镀液中ZnSO4／(ZnSO4+FeSO4比值的关系，结果表明，镀层为非晶态时，显微硬度最高。300-400℃热处理后，镀层的显微硬度达最大值。更多还原

【Abstract】 In this thesis, electroless plating and its deposition principle were briefly introduced. The progress of electroless plating in the past decade was summarized which includes nickel based alloys, cobalt basd alloys, copper based alloys and iron based alloys. The binary amorphous alloy Fe-Zn was obtained on copper substracts by electroless plating at the first time. The investigation for the plating procedure indicates, the practical optimum bath for Fe-Zn amorphous alloy was : FeSO4 ?7H2O 8g/l, ZnSO4 -7H2O 7g/l, KNaC4H4O6 -4H2O 65g/l, NaH2PO2 -H2O 8g/l, NaOH 35g/l , H3BO3 lg/1 , detrin lg/1; plating temperature: 55癈, and plating time: 20 minutes. The content, surface appearance and structure of deposits were studied. The corrosion resistance characters of electroless plating Fe-Zn in 10% NaOH Solution and 3.5% NaCl solution were alsostudied. The results indicate that the deposits had better corrosionresistance character than other iron based deposits. The dependence between the ratio of ZnSO4/(ZnSO4+FeSO4) in solution and the deposits microhardness was studied.lt showed that amorphous state deposit had higher value. After heat treatment at 300-400 癈, the microhardness of deposits got highest value.更多还原
