The Effect of the Surface Roughness Profile on Micropitting

The roughness profile of metal-to-metal contacting parts is one of the most important characteristics in making mechanical systems more durable and energy efficient.

Materials Matter: Optimizing Performance with Surface Finish and Lubrication

Lubrication in mechanical power transfer systems can have superfluous or detrimental properties if not optimized relative to the surface finish of the components.

Materials Matter: Comparing Surface Roughness Parameters

Measurements such as Ra, Rz, and Rsk may not effectively evaluate isotropically superfinished surfaces.
