METHOD FOR MANUFACTURING A CERAMIC COATING LAYER FOR IMPROVING ABRASION-RESISTANCE OF A METAL THROUGH AEROSOL EVAPORATION, AND A CERAMIC COATING LAYER OF METAL USING THE SAME

摘要

PURPOSE: A method for manufacturing a ceramic coating layer for improving abrasion-resistance of a metal is provided to can obtain additional functions without abrasion-resistant effect by evaporating ceramic powder on one selected from titanium dioxide, aluminum oxide and yttria-stabilized zirconia.;CONSTITUTION: A method for manufacturing a ceramic coating layer for improving abrasion-resistance of a metal comprises: a step of preparing a metal substrate; a step of heat-treating the ceramic powder at constant temperature; a step of forming a ceramic coating layer by evaporating through aerosol evaporation of the ceramic powder on the metal substrate. The ceramic powder is one selected from titanium dioxide(TiO2), aluminum oxide(Al2O3), yttria-stabilized zirconia, and ceria(CeO2). The metal substrate consists of one selected from magnesium or magnesium alloy, aluminum or aluminum alloy, carbon steel, and stainless steel. The heat treatment is conducted at the temperature of 500-700 °C, for 1-5 hours.;COPYRIGHT KIPO 2012
