Mechanical characterization of alumina coatings on C35 steel

C35 steel substrates were alumina-coated via thermal plasma spraying. Before coating, the steel surface was either sandblasted, or pre-oxidized in CO2. The pre-oxidized samples exhibited coatings adhesions of 82±7MPa, and only 45±4MPa for the sandblasted ones. This good result was attributed to the...
