Abstract

Gears have numerous practical applications. It is an essential
element for power transmission. It is used to increase or decrease the speed or
change the direction of a power resource. When gears are operating, it will
develop high stress concentration on the contact tooth surface. In practice most
gear teeth fail due to surface contact, which is the most common failure.
Selecting the ideal material for a gear tooth is significant for the purpose of
operating gear system. This review study will increase additional understanding
of ceramic functional graded materials (FGMs) and their applications and how
these materials can solve the gear tooth surface problem. This study gives
evidence that FGM is able to enhance the microstructure, mechanical properties
of the gear and gives better hardness between two tooth surfaces. The
conclusion will suggest a solution for the problem of contact surfaces in the
gear tooth, by using functional graded materials. In the structure of FGM, the
metal phase will provide strength to the gear tooth and the ceramic phase will
augment the heat and wear resistance.
