摘要： PURPOSE:To easily form a heat insulating coating layer on a high temp. part such as a turbine blade by adding a very small amount of ZrO2 powder contg. MgO or Y2O3 to fuel and by burning the fuel in a burner. CONSTITUTION:ZrO2 powder contg. 4-30% MgO or Y2O3 is added to fuel such as gaseous propane in 1/1,000-1/10,000wt. ratio of powder/fuel. The fuel is burned in a burner to deposit the metallic oxide powder on the surface of the high temp. part of the burner and to carry out coating for heat insulation. In this way, a worn or partially peeled heat insulating coating layer on the high temp. part can easily be restored without suspending the operation of a gas turbine or the like.
