  • 摘要：为比较电刷镀与喷射电沉积制备纯钴镀层的差异,在相同的电流密度下分别利用两种方法制备纯钴镀层.通过分析镀层的表面形貌与性能,发现采用电刷镀技术制备的纯钴镀层表面更加平整致密,性能更加优异,表明电刷镀技术在制备纯金属镀层时具有明显的技术优势.%Pure cobalt coating was prepared respectively by electro-brush plating and jet electrodeposition at the same current density in order to compare the differences.Through analyzing the surface morphology and properties of the coatings,it was found that the pure cobalt coating prepared by electro-brush plating has smoother surface and better properties,indicating that electro-brush plating has obvious technical advantages in the preparation of pure metal coatings.
  • 摘要：Through analyzing the faults examples,such as current is limited and coating is easy to burn and gray,occurring during sylvite zinc plating,it was pointed out that both equipment faults and process faults could cause these phenomena.The equipment faults were divided into four kinds,the methods of finding the fault cause and the methods of dealing with it were introduced,and the technical measures for preventing similar faults and faults discrimination experience for sylvite zinc plating were summarized.%通过对钾盐镀锌中“电流开不大,镀层易烧焦、灰暗”等故障实例的分析,指出钾盐镀锌中“设备故障”和“工艺故障”均会造成这一故障现象的产生.将其中的“设备故障”分为4个种类,给出了故障原因的查找方法和故障处理方法,总结了钾盐镀锌中预防同类故障发生的技术措施和故障判别经验.
