| Abstract: | The process formulation and flow of low- temperature iron plating were introduced. The structure morphology of deposit was observed by SEM, the hardness of deposit was tested by hardness tester and the adhesion strength of deposit was examined by file and thermal shock methods. The effect of pH on the deposition rate, micro- hardness and corrosion resistance was studied. The results showed that the deposit has good adhesion, and at pH 1.0, it has best corrosion resistance and the highest deposition rate can... |
