The differences between the two passivation processes are as follows:
(1)80 degree passivation is passivation treatment at a high temperature of 80 degrees. However, normal temperature passivation is passivation at 5325 degrees at room temperature.
(2) The effect is different: 80 degrees passivation treatment time is short, the treatment effect is good. However, the normal temperature passivation treatment time is long, the effect is not as good as the high temperature passivation treatment.
