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. Chro...

... results of uncoated austenitic stainless steel 316L cyclic oxidized in air at temperature between 700ºC and 900ºC for 52hrs at 4hrs cycle ( figure 5 and table 2), show that, the oxidation rates are increased as temperature increased. This results from external Cr 2 O 3 layer which protects them from rapid oxidation. ...

An aluminide–silicide coating was prepared on a pure tungsten substrate by halide-activated pack cementation. Thickness, morphology, and phase structure of the Al–Si coating were systematically investigated. Thermal cyclic oxidation tests of the Al–Si coating were carried out at 1,000°C. The results revealed that the aluminide and silicide coating...
The oxidation behavior of four valve steels (X33CrNiMn23-8, X50CrMnNiNbN21-9, X53CrMnNiN20-8 and X55CrMnNiN20-8) covered with thin sputter-deposited coatings containing chromium and nickel was studied under isothermal and thermal shock conditions. It was determined that coated steels exhibit greater resistance against oxidation than steels with unm...
Alumina-forming austenitic stainless steels (AFA-SSs) are candidates for high temperature applications to replace conventional stainless steels that form unstable chromium-oxide. In this work, a new AFA-SS composition was designed, through thermodynamic considerations, oxidation model calculations, and Genetic Algorithm-based optimization, which is...
Simultaneous deposition of chromium and silicon by pack cementation is very effective in
protecting substrates from hot corrosion and oxidation environments at high temperature. In this study,
chromium and silicon were simultaneously deposited by diffusion into austenitic stainless steel 316L alloy
by the pack cementation process using a pack mixtu...
