Materials Matter: Isotropic Superfinishing
Increasingly stringent operational requirements from customers coupled with enhanced global technical standards have heightened the focus of gear designers on a wide array of parameters that historically would have been of secondary consideration; one such design parameter is surface finish.

Superfinishing and its Effect on Micropitting
Micropitting is a prominent failure mechanism for both highly stressed case carburized gears and bearings that operate consistently in low speed, low load environments where boundary conditions predominate.

The Impact of Surface Condition and Lubricant on Gear Tooth Friction
Frictional losses in gear boxes are of significant interest to gear box designers as these losses transform into heat. The direct result is a reduction in the fuel efficiency of the vehicle involved.
