Materials Matter: Comparing Surface Roughness Parameters
Effective gear design must account for a range of potential failure modes. As discussed in previous Materials Matter columns, gear failure modes can be fatigue-based and progressive (such as micropitting) or sudden (such as scuffing)....

Materials Matter: Scuffing
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....

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 Effect of the Surface Roughness Profile on Micropitting
A wide choice of surface roughness parameters is available to characterize components, such as gears or bearings, with the goal of predicting the performance of such metal--to--metal contacting parts....
