The Rapid ISF® Process
REM Surface Engineering's automotive process, Rapid ISF® (Isotropic Superfinishing), is able to produce a planar surface of Ra .1 µm or less in 4 minutes. The Rapid ISF Process increases fuel efficiency and power density and is compatible with a ju...

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....
