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...

| description | 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 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. |
