ABSTRACT:
A linearly extending metallic element includes at least one relatively hard arcuate surface formed by ion implantation. The elements are utilized in an overrunning clutch and can be rollers or sprags. The clutch roller has the entire arcuate surface treated while the clutch sprag has only the opposed arcuate ends treated. In addition, tracks on the inner and outer races of a clutch can have relatively hard surfaces formed by ion implantation for contacting the rollers and the sprags.
