Abstract
An air turbine starter having a housing that includes an inlet and an outlet to define an air flow path from the inlet to the outlet. A stator includes a plurality of circumferentially spaced vanes extending into the air flow path and defined a stator core. A coating surrounds one or more portions of the housing, defining the housing core, or the stator, defining the stator core. The housing core or the stator core includes a first material having a first hardness and the coating comprises a second material having a second hardness.
Claims18
An air turbine starter comprising:
- a housing having an inlet and an outlet to define an air flow path from the inlet to the outlet;
- a stator rotationally stationary relative to the housing and having a plurality of circumferentially spaced vanes extending into the air flow path;
- and
- a coating applied to one or more portions of both the housing and the stator, wherein the coating includes one or more portions that confront the air flow path and one or more portions that do not confront the air flow path;
- wherein the housing or the stator comprise a first material having a first hardness, and wherein the coating comprises a second material having a second hardness that is greater than the first hardness;
- and
- wherein the coating includes a coating thickness, and wherein the coating applied to the housing and the stator that confronts the air flow path along among both the housing and the stator is thicker than the coating that does not confront the air flow path.
