Abstract

Cellular and dendritic structures were observed for the laser-cladded high chromium and high nickel stainless steels. The cooling rate was calculated to be 2.43×103∼3.73×103 K/s during solidification. X-ray diffraction analysis showed that γ (200) rather than γ (111) was the predominant crystallographic plane, and its intensity increased with increasing silicon content. A ferrite phase was formed in the otherwise austenitic matrix as the silicon content increased to 3.32 wt%. The oxidation resistance of the LSC alloys at 900°C increased with increasing silicon content. The oxidation rates of the LSC stainless steels with silicon content greater than 1.84 wt% were lower than that of AISI 310 SS.
