Abstract
A method for thermally conditioning a disc drive swage mount to enhance torque retention capability and plate stiffness wherein the swage mount is baked in an oxygen depleted environment to an elevated temperature within a predetermined range of temperatures which activates inherent frictional properties therein and controllably cooled non-linearly through a series of thermal cycles then instantaneously quenched to alter the material grain structure forming the swage mount. After the component is quenched, it is returned to ambient conditions for assembly into such disc drives.
