Development of high temperature resistant modified aluminide and titanium aluminide coatings on stainless steel 316

Stainless steel 316 was coated with CeO2 and Y2O3 modified aluminide and titanium aluminide coatings. The coatings were prepared by the pack cementation method and the high temperature oxidation behaviour of the coatings was investigated in an atmosphere containing a limited supply of air. The perfo...

Description
Summary:Stainless steel 316 was coated with CeO2 and Y2O3 modified aluminide and titanium aluminide coatings. The coatings were prepared by the pack cementation method and the high temperature oxidation behaviour of the coatings was investigated in an atmosphere containing a limited supply of air. The performance of the coatings was studied by measuring oxidation kinetics, and by scanning electron microscopic techniques. The oxidation rates of these coatings were reduced in the presence of CeO2 and Y2O3 due to better adherence of their oxide scales.
