SIMULATION OF CARBURIZING CONCENTRATION FIELD OF METAL DUSTING CORROSION WITH APPLIED LOADING

摘要：

Metal dusting is a catastrophic phenomena of high temperature corrosion, which occurs in severe carburizing environments (carbon activity aC>1.0) at temperatures 400-900℃. Metal dusting causes not only phase changes but also removal of materials (pitting or thinning) and serious material deterioration. Carburizing is the precondition of the occurring of metal dusting corrosion, and the ultimate cause of phase changes and removal of materials. Generally the effect of the loading has not been considered against metal dusting corrosion in present study. This paper focuses on the simulation of carburizing concentration field by finite element method under the condition of metal dusting and applied loading, which is compared with the experiment results. A preliminary study of the coupling effect of diffusing and applied loading (chemical and mechanical) has been carried out.
