    摘要: A hard film comprises an oxide film of corundum crystal structure having a lattice constant in the range of 4.779 to 5.000 Å and a thickness not smaller than 0.005 &mgr;m, and an alumina film of corundum crystal structure formed on one of surfaces of the oxide film. The oxide film is formed of Cr2O3, (Fe, Cr)2O3 or (Al, Cr)2O3. The alumina film excellent in heat resistance and wear resistance can be formed on a base object under a low-temperature condition that will not deteriorate the characteristics of the base object.
