Abstract: A disc of a composite ceramic material composed of silicon nitride (Si3N4) and 20% hBN was prepared and its tribological characteristics were investigated by sliding a Si3N4 pin across its surface at different sliding speeds. The friction coefficient and wear coefficient were determined for the composite using two different test modes: one in which the pin was kept stationary and the disc was rotated on top of the pin, and one in which the disc was kept stationary and the pin was rotated on top of it. It was found that the tribological characteristics of the material depended on the test mode, and that the sliding speed greatly affected these characteristics.
