Stress analysis was carried out on two kinds of friction tests (pin-on-disk test and block-on-ring test). The test procedure of pin-on-disk test is standardized as JIS R 1613. If we follow the procedure as stated in this document, a tensile stress from several hundred MPa to 1 GPa is generated on the test surface. This value equals the tensile strength of typical engineering ceramics, meaning that this test condition corresponds to severe wear conditions with possibility of mechanical fracture on the surface. In the block-on-ring test, the surface tensile stress is one-digit smaller compared to that of the pin-on-disk test, under the same testing force. It is thus assumed that the block-on-ring test can measure wear under mild conditions without the risk of mechanical fracture on the surface. It is important to use an appropriate friction test method that fits with the application of the investigated material, for properly discussing the friction property of ceramic materials.
