The wear behavior of MgO single crystals on sintered alumina has been investigated under the condition of vibrational sliding. As a result, it was found that the rate of wear of MgO in the period of initial and transient frictions was very high, but it was rapidly decreased after the vibrational sliding of 10<SUP>4</SUP> cycles. The wear, the progress of which was shown by a discontinuous wear diagram like step pattern, was caused by the internal cracks.<BR>The wear volume of MgO in the initial and transient state of wear were widely changed by the amplitudes of vibrational sliding; the rate of wear below the amplitude of 100μm was lowered by two orders of magnitude smaller than that above the amplitude of 100μm. Meanwhile, the amplitude hardly affected the rate of wear in the steady state. Also, the rate of wear was linearly increased in proportion to the increase of contact load in all wear state.
