Abstract


Using the three-step method (pre-oxidation, primer deposition and coating deposition), a well-adhered γ-Al2O3 coating on FeCrAl metallic support was attained. The research researched the primer deposition including the influence of the acidity ([H+]/[AlOOH]) in starting dispersion, aging time and temperature.

Keywords
