METHOD OF SURFACE MODIFICATION FOR THERMAL SHOCK RESISTANCE AND MEMBER THEREOF

摘要

A method of enhancing the thermal shock resistance of surface of ceramic member whose thermal shock resistance is demanded, characterized in that the thermal shock resistance of ceramic member whose thermal shock resistance is demanded is enhanced by forming a uniformly distributed linear dislocation structure on the surface of ceramic member whose thermal shock resistance is demanded with the use of a spray material of microparticles with convexly curved surface of 5 to 200 mum average particle size, which microparticles has a Vickers hardness (HV) of >=800 being not higher than the hardness of the ceramic member whose thermal shock resistance is demanded.
