Materials Matter: Micropitting

Posted by Martin McCormick on Samstag, September 17th, 2016 in

Micropitting is a gear failure mode that typically occurs when higher contact stresses are applied to hardened gear teeth. Unlike most other failure modes, micropitting does not always proceed to component failure if left unaddressed....

Materials Matter: Scuffing

Posted by Martin McCormick on Samstag, September 17th, 2016 in

Gear meshing is one of the most complex areas of study in tribology. Meshing consists of both sliding and rolling motion and can be affected by a number of other operating parameters....
