| 中文摘要: |
| 铸铝箱体件很容易因磨损而报废，对磨损后的铸铝箱体件采用Ni-P合金刷镀再修复，可恢复铸铝箱体件的原始配合尺寸，提高其使用寿命。研究了刷镀铸铝箱体零件的Ni-P合金刷镀液、特殊预处理液的配方及电刷镀工艺。特殊预处理工序有效地防止了铸铝表面的再氧化，使后续刷镀层结合力好，避免了刷镀层易剥落的弊端。铸铝刷镀过镀层采用高堆积碱铜，工作层采用Ni-P合金。刷镀层硬度高(可达613HV)，耐磨性好。该工艺方法解决了铸铝箱体件磨损后修复难等问题。 |
| 英文摘要: |
| Aluminum-cast boxes often tum useless due to abrasion. But such boxes can be restored by brush plating of Ni-P alloy. The simple process can recover the original fitting size of the castings and prolong the service life of the boxes. The formula of the Ni-P brush plating bath, the specific pretreatment solution and electro-bursh plating procee were studied. The specific pretreatment effectively prevents the reoxidation on the surface of the casting, provides a strong binding force for the plating, and fixes the defect of spalling. On the alurmnum casting, high tap alkaline copper is applicated as the interface layer, and Ni-P alloy as the working layer. The plating process gives the boxes hard coating ( 613HV hardness) and good wear-resistance, thus can solve the difficult problem of restoring abraded aluminum-cast boxes. |
