A series of refractory mold coatings were applied to cast iron specimens, and their resistances to wear and spalling were investigated. Tests were carried out with own made measures, and also a calculation was tried for the comparison of a part of results like spalling. Worn width by scrubbing the indenter on the coating layer increased significantly at high temperature. Temperature increasing rate across the specimen when the coating side was exposed to 1,000oC was in the range of 14.5~75.8oC/sec·mm, and specimens with thicker coating layer showed lower temperature increase. Severe spalling of coated layer was observed after heating the specimen, and it was able to confirm by calculation using a commercial code.
