• The penetration phenomena of liquid Mn to porous Al2O3 coating plasma-sprayed on SS400 steel substrate was studied by heating at 1 573 K in vacuum atmosphere. Moreover, the possibility of improving the Al2O3 coating properties was examined. The formation of MnAl2O4 was clearly recognized in the connected porosity of Al2O3 coating penetrated with liquid Mn. It was revealed that the hardness and the fracture stress of the composite coating consisted of Al2O3 and MnAl2O4 without porosities after heat-treatment with Mn increased greatly compared with as-sprayed Al2O3 coating.
