    In order to improve the corrosion resistance of the oxide film, stainless steel springs are usually immersed in soap or dichromate solution to fill or passivate the pores of the oxide film, and then oil, main shaft oil, transformer oil, etc. are used The pit was filled. Stainless steel springs are usually treated with 5%-10% soap solution at 80-90 ℃ for 3-5min. It can also be treated with potassium dichromate solution with mass fraction of 3% ~ 5%, temperature 90-95 ℃, time 10-15min.
    The passivated or saponified spring water needs to be washed with warm water, dried in the sun or in the sun, and then soaked in spindle oil at 105-110 ℃ for 5-10 minutes. Take it out and stand for 10-15 minutes to make the oil on the residual surface flow out. During oxidation treatment, the following items shall be noted to ensure surface quality:
    1) Before the spring is oxidized, the oil stain, oxide skin and heat treatment salt residue on the surface must be removed.
    2) The contact copper coating on the spring surface must be cleaned in the copper removal tank before entering the oxidation tank.
    3) Copper and copper alloy springs shall not enter the oxidation tank.
    4) The hanging basket or hook used for oxidation treatment shall not be made of copper or copper alloy, nor shall it be brazed.
    5) Before oil immersion, the spring must be replaced with a special oil immersion basket, and it shall be inspected to be qualified. After confirming that the spring is qualified, oil immersion can be carried out.
    6) In order to make the oxide film on the spring surface uniform, if possible, the spring should be installed into the basket according to certain rules (vertical position is recommended), or during the oxidation process, the basket should be inverted in the basket changing groove for 1-2 times, so as to eliminate the defect that there is no oxide film or the oxide film is very thin at the contact between the springs.
    7) The oil immersion tank shall be carried out under the specified oil temperature, and the oil tank can be removed only after the foam is basically eliminated.
    8) Soap should be added to the saponification tank in time. Be careful not to boil the solution to avoid overflowing the tank.
    9) It is recommended that the cleaning water should be flowing water, the liquid level should be kept stable, and the water should be changed at the specified time.
