| Abstract: |
| In order to search for the influence of phosphatizing on high-speed steel tool life, we adopted zinc phosphate rapid hot phosphatizing and monobasic manganese phosphate hot phosphatizing tools with various technics specification, so we can know that phosphatizing can improve the life and corrosion stability of metal tools via comparing the cutting character and corrosion stability of the phosphatized tool with the tool that not been phosphatized. This paper has introduced the influence of the factors of quality checking methods on phosphate coating, analysed the surface roughness of parts, steel alloying element, microstructure, phosphate liquid temperature,acidity, phosphatizing time etc. to phosphatizing with emphasis; analysing the theory of phosphatizing which improve tool life and corrosion stability, acquired the reason that phosphatizing improving tool life and corrosion stability is that the heat conducting capability of phosphate coating is bad, so that it make the tool cutting chin temperature increasing not easy, and it improved the surface lubricating condition of the tools simultaneity. |
