This paper discusses the grindability of sprayed coatings of Al 2 O 3 (-TiO 2 ). The actual grinding action was investigated experimentally by surface grinding using a resinoid diamond wheel with different particle sizes and concentrations.The maximum height of the grinding surface was lower when the grain size of the wheel was larger and the degree of concentration of the wheel was higher. The abrasion of the grinding wheel was not due to the abrasion by the abrasive grain, but to a selective removal of the combining material during grinding and a reduction of the holding strength of the abrasive grain. This phenomenon was remarkable when the degree of concentration was low.
Thermal spraying has emerged as an important tool of increasingly sophisticated surface engineering technology. Therefore, the demand for technology that is checked non-destructively has become more insistent. This paper presents the nondestructive evaluation of fl aking-resistance in thermal sprayed Al 2 O 3 , ZrO 2 and TiO 2 coating. The full-width at half maximum taken from the X-ray diffraction peak profi le was used as a nondestructive evaluation method in this study. The results by the nondestructive method were compared to the results with scratch test. It was found that nondestructive evaluation of the thermal sprayed ceramic coating was effective.
