摘要：本课题研究了在超导带材表面电镀铜，并不影响超导材料的性能，且环保无污染的绿色工艺。搭建连续镀铜线，对超导带材进行电镀。对于生产得到的产品用金相显微镜法，对镀铜层进行表面外貌、镀层厚度性能的评价。本研究考虑到了环保要求以及对于镀层的质量要求，以及对于各类电镀液配方的研究最终采用酸性硫酸铜镀铜法。工艺评价主要是以铁基超导带材作为基材，采用硫酸镍普通镀镍法进行预镀之后使用酸性硫酸铜镀铜法进行电镀，采用不同电流、带速进行酸性电镀铜比较镀层质量。结果表明，所采用的工艺能成功电镀，并且镀层厚度达到要求且不影响材料的超导性能。该工艺对各种试剂的使用量都相对较少，节约了经济成本，除了使用了配方中必须使用的浓硫酸之外没有使用其他有危害的化学品，较为绿色环保。79564

Evaluation of alkaline electroless nickel plating-1

Abstract: In this paper, the electroplating of copper on the surface of superconducting tape is studied, which does not affect the performance of superconducting materials and the environmental pollution。 Build continuous copper wire, superconducting strip plating。 For the production of the product by metallographic microscope method, the copper layer on the surface appearance, the thickness of the coating performance evaluation。 This study takes into account the environmental requirements and the quality requirements for the coating, as well as the use of acid copper sulfate copper plating for the study of various types of electroplating formulations。 The evaluation of the process is mainly based on iron-based superconducting tape as the substrate, using nickel sulfate nickel plating method for pre-plating using acid copper sulfate copper plating method, using different current, the speed of acid plating copper plating quality。 The results show that the process can be successfully electroplated, and the coating thickness to meet the requirements and does not affect the material superconducting properties。 The process of the use of various reagents are relatively small, saving economic costs, in addition to the use of the formula must be used in addition to concentrated sulfuric acid without the use of other hazardous chemicals, more green。
