PURPOSE:To manufacture a thermal spray material excellent in heat resistance, thermal impact resistance and corrosion resistance by blending 2CaO.SiO2 with MgO.4ZrO2 in a specified ratio. CONSTITUTION:A thermal spray material of 2CaO.SiO2-MgO.4ZrO2 series oxide constituted of, by weight, 50<=2CaO.SiO2<=90 and 10<=MgO.4ZrO2<=50 as well as 2CaO.SiO2+MgO.4ZrO2=100 is prepd. Furthermore, the grain size of the above oxide material is regulated to 5 to 500mum, and its average grain size is preferably regulated to 0.1 to 100mum in particular. In this way, a thermal spray material excellent in heat resistance, thermal impact resistance and corrosion resistance is obtd., and by applying plasma spraying to the surface of a substrate, a member having excellent thermal shielding effect and corrosion resistance can be manufactured. |
