Research Institution
The use of materials other than steel in bearing liners lead to many problems associated with variations in thermal expansion coefficients. The use of an aluminum matrix composite minimized this problem because adding ceramic reinforcements to the aluminum matrix reduces the expansion coefficient to that of the steel. In addition, the ceramic increases the elastic modulus and increases the wear resistance. This proposal uses a new spherical alumina as the reinforcement for ease of machining in addition to the other properties.
