Effect of aging heat treatment on corrosion behavior and corrosion kinetics of 17-4PH stainless steel in artificial saliva

The corrosion behavior of the sintered 17-4PH stainless steel samples aged at different conditions in artificial saliva was studied using the method of electrochemical and weight loss after exposure for various periods of time. The results showed that the samples aged at 480 °C for 1 h exhibited...
