Abstract EN
The application of a pack cementation of chromium and silicon coatings on austenitic stainless steel 316L alloy yields a significant improvement in the oxidation and hot corrosion resistance over a wide temperature range (300-900oC).
In this work, austenitic stainless steel 316L alloy is coated with chromizing-siliconizing diffusions coatings.
Chromium and silicon were simultaneously deposited by diffusion into austenitic stainless steel by the pack-cementation process using a pack mixtures containing (67 wt.
% Cr, 8wt.
% Si, 2wt.
% NH4Cl and 23wt.
% Al2O3) when required.
It was found that diffusion coating time of six hours at 950oC produces coating thickness of 80-100μm and consist mainly of CrSi2 and Cr3Si phase.
