    摘要: A joint assembly for coupling a ceramic member to a metal member is comprised of a ceramic shaft portion attached to the ceramic member; a slotted shrink fitter formed of a first metal and disposed around and in torque transmitting contact with the ceramic shaft portion to define a first interface surface therebetween; and a sleeve formed of a second metal disposed around and in torque transmitting contact with the shrink fitter to define a second interface surface therebetween. Either the shrink fitter or the sleeve attached to the metal member. The coefficient of thermal expansion of the second metal is relatively low compared to that of the first metal and the diameters of the first interface, (d1), and the second interface, (d2), are determined from the equation, d1/2=(&agr;c−&agr;1)/(&agr;−&agr;1) where &agr;c, &agr;1 and &agr;2 are the coefficients of thermal expansion of the ceramic, the first metal and the second metal respectively. A compliant sleeve is disposed the ceramic shaft portion and the slotted shrink fitter.
