Powder metallurgy plating
[Abstract]:
For the electroplating treatment of powder metallurgy products, the current popular method is to seal the pores of porous parts such as powder products with resin, wax or some molten compounds. The method of filling the pores is used to avoid problems caused by incomplete cleaning. At the same time, the powder metallurgy plating process should be selected to avoid the solution containing strong corrosive or corrosive media, such as chloride ions in the solution.
To fill the holes, you must use high-temperature baking before filling to remove oil fume. This can remove the oil remaining in the holes to help the sealant enter and combine. After removing the oil, it can be impregnated with resin to seal. Better. For general products, zinc stearate is usually immersed at 150-180 degrees, and the sealing effect is also good. However, the use of strong acid should be avoided in the powder metallurgy plating process to avoid dissolving the sealing material.
