Gear Corrosion During the Manufacturing Process
No matter how well gears are designed and manufactured, gear corrosion can occur that may easily result in catastrophic failure. Since corrosion is sporadic and a rare event and often difficult to observe in the root fillet region or in finely pitched gears with normal visual inspection, it may easily go undetected.

High Speed, Automatable Superfinishing of Rear-Axle Hypoid Gears
The benefits gained by superfinishing rear-axle hypoid gearsets are now well documented. Friction, wear and operating temperature are significantly reduced. The main impediment to commercially implementing this process, however, is that it increases manufacturing cost in terms of process speed, work in process and labor.

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.
