Fluidized Bed Process

In the present investigation, low temperature nitriding has been attempted on AISI 316L austenitic stainless steel by using a laboratory fluidized bed furnace. The nitriding was performed in temperature range between 400°C and 500°C. X-ray diffraction, metallography, and corrosion tests were used to characterize the resultant nitrided surface and layers. The results showed that fluidized bed process can be used to produce a precipitation-free nitrided layer characterized by the S phase or expanded austenite on austenitic stainless steel at temperatures below 500°C. But there exists a critical temperature and an incubation time for effective nitriding, below which nitriding is ineffective. The corrosion behaviour of the as-nitrided surfaces is significantly different from that previously reported for low temperature plasma nitriding. This anomaly is explained by the formation of iron oxide products and surface contamination during the fluidized process.

Plasma Carburizing

Plasma carburizing of AISI 316L austenitic stainless steel was carried out at low temperature to improve the surface hardness without degradation of its corrosion resistance. The microstructure, surface hardness, phase composition and corrosion property of the hardened layer were analyzed. The experimental results show that high-quality hardened layers can be produced at the carburizing temperatures between 673 K and 773 K, which have not only high surface hardness and wear resistance, but also good corrosion resistance. All of the hardened layers display a precipitation-free structure or Sc phase. The chromium carbides began to precipitate in the hardened layer as soon as the carburizing temperature is higher than 823 K. The precipitation of chromium carbides will lead to deterioration in corrosion resistance of the hardened stainless steel.
