The Effect of Superfinishing on Gear Micropitting, Part II
It should be noted from the outset that the data presented in Part I and Part II of this paper was generated by independent laboratories. Superfinishing of the gears was the authors’ sole contribution to these studies.

Materials Matter: Gear Corrosion in the Manufacturing Process
No matter how well gears are designed and manufactured, gear corrosion can occur during the manufacturing process, which may, in turn, result in catastrophic failure.

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: Lambda Ratio
The lambda ratio was originally developed to quantify the quality of lubricant operating regimes relative to bearing performance.

Materials Matter: Micropitting
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
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.

Materials Matter: Wind Turbine Gear Repair
Wind turbine gearbox durability has improved significantly over the past ten years. The days of early gearbox failure due to epidemic micropitting are largely in the past.

Materials Matter: Power Density and Isotropic Superfinishing
Power density, also described as load-carrying capacity, is simply the amount of load that can be safely transferred by a gear or other power transfer component without failure.
