    A ceramic coating material of hard alloy powder used to make cutting tool is prepared through proportionally mixing Al(C3H7O)3, deionized H2O and HNO3, keeping constant temp. at 85 deg.C while strong stirring for 48 hr to obtain Al2O3 sol, adding the said hard alloy powder to it, strong stirring while ultrasonic vibration, laying aside for layering, filtering, and vacuum drying. The cutting tool made of it has high resharped hardness and high antiwear nature.
