With the development of tool materials and large diameter, the mechanical properties of tool steel body are required to be higher, that is, to improve the elongation on the basis of high tensile strength. In order to facilitate the fillet rolling production of gear shaft and improve the fatigue resistance of gear shaft, the traditional quenched and tempered steel and non quenched and tempered alloy steel gear shaft are replaced. Next, metal will be introduced How the surface treatment of materials is carried out.
Then put it into the cleaning solution for 10-20 minutes, and the ultrasonic power is 25-85 watts per cubic decimeter. The quality components of the cleaning solution are: 1.2-2 parts of tartaric acid, 25-45 parts of carbon monoxide deoiling, 80-100 parts of iron sulfate, 20-30 parts of manganese sulfate, 80-100 parts of deionized water and 20-30 parts of polyvinyl alcohol.
The metal surface treatment method is to fill the gap of the metal surface with quenching oil to improve the corrosion resistance of the material surface, and then carry out intensive cleaning and cavitation treatment on the metal surface under the action of ultrasonic wave. It can make the adhesion force of the metal surface relatively balanced, so as to improve the corrosion resistance and wear resistance of the metal surface and the adhesion property of the powder.
After cleaning, rapid drying and ultraviolet irradiation can make the organic acids on the metal surface solidify and adhere quickly, and improve the hydrophobicity of the metal surface.
