The corrosion behavior of sintered 17-4PH stainless steel samples aged at different conditions in artificial saliva was investigated. Samples aged at 480 degrees Celsius for 1 hour exhibited the highest corrosion resistance, with corrosion kinetics following a bimodal function form rather than a classical power-law function. Pitting corrosion was mainly initiated from existing, isolated pores and further accelerated.
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 degrees C for 1 h exhibited the highest corrosion resistance. The pitting corrosion was predominantly initiated from existing, isolated pores and further accelerated The corrosion kinetics trend is found to be more consistent with a bimodal function form rather than the classical power-law function.
