Durability

Component durability is the primary characteristic of component quality.  Component durability also directly affects the operation and maintenances cost of a given mechanical system.  REM Surface Engineering’s isotropic superfinishing processes increase the surface durability & bending/dynamic fatigue resistance of mechanically loaded components such as gears and bearings, rotating components such as airfoils, and many other metal-to-metal contacting or cyclically loaded components.

REM’s ISF® Surface is unique as it eliminates the asperities left behind by metal forming operations, and it converts the surface to an isotropic texture, devoid of sharp v-notch failure points.  These surface characteristics provide increases to both contact and dynamic fatigue resistance as well as reductions in abrasive wear and surface contamination. These performance benefits increase the durability of a component by 300% or more[1], thereby increasing its quality and value. For lubricated mechanical systems, REM’s isotropic superfinishing processes also generate increases to the operating lambda ratio, which results in significant increases in scuffing resistance.[2][3]

REM’s ISF Technologies are technically validated, proven methods of increasing component durability, reducing system debris, and improving operational performance.  These processes can be applied to a wide range of components types, sizes, and metals.  REM’s isotropic superfinishing processes are available via outsourced processing at a REM facility or as technology installations at a customer site.  Contact us today to learn more or to start a project.
