| Abstract: | In order to improve electroless nickel plating technology of aluminum alloys and avoid contamination of zincate conversion process on electroless nickel plating solution, activation-electroless Ni pre-plating technology for aluminum alloys was investigated. The optimal conditions are determined that pH value in activation process is in the range of 9 to 10 and pre-plating time is about 4 to 5 minutes through coating adhesion and porosity and corrosion resistance tests. The coating quality meets the GB/T 13913 -92 specifications, thus the technology provides a new pretreatment for aluminum alloys and can be used to substitute the zincate conversion process. |
