High Temperature Bearing and Dry - Lubrication Concepts
Abstract
The Phase I program accomplished the study and functional evaluation of solid lubricant formulations in conjunction with the use of a specially designed and built test-bed bearing. The bearing was fabricated from hot pressed Silicon Nitride (HPSN). Special attention was given to problems associated with the design, material selection and lubrication of the ball-retainer. Much emphasis was also given to finding better methods of supplying lubricants to assure better bearing performance and to substantially extend the useful life of any type of solid lubricated bearing. Investigations were made into ways of finding better methods of bonding the solid lubricants to the ceramic substrate materials without the loss of low friction qualities. Adhesion testing was accomplished by coating coupons of candidate materials. Rub-show tests were conducted using the same family of substrate materials; also some commercial and all the proprietary solid lubricant formulations were submitted to a series of wear tests.
