| Abstract: |
| Low temperature phosphating process has attracted much attention day by day because of its low energy consumption, low cost and low environmental pollution. The characteristics, mechanism, accelerants and present situation of low temperature phosphating process have been studied. It indicates that electro-chemical method, chemistry method, acidity and pH adjustment have been used in order to reduce the phosphating temperature, but low temperature phosphating still has the low corrosion resistance and can not suit for the large-scale industrial application. Because of the complexity of phosphating process, the study on the low temperature phosphating mechanism and compound accelerants will still be the key point. |
