Advantages and disadvantages of the phosphating process
The phosphating process, as a widely used surface treatment technology for metal corrosion protection, has the following advantages and disadvantages: Advantages: Good anti-corrosion properties: the phosphating film can effectively isolate the metal from contact with corrosive media, and significantly improve the corrosion resistance of the metal, thereby extending the service life of metal parts. Enhance the adhesion of the coating: the phosphating film has good adhesion, which can provide an excellent substrate for the subsequent coating treatment (such as painting, electrophoresis, etc.), enhance the bonding of the coating with the metal surface, and improve the quality of the coating. Reduce friction and wear: phosphate film has a certain lubricity, can reduce the wear of metal in the friction process, and improve the use of parts and life. Mature technology, simple operation: phosphating process after years of development, mature technology, easy to operate, suitable for mass pro...
