This paper presents the Combined Micro Relief (CMR) method developed by the authors. CMR is a two-step process: grooving and FriCSo lapping. The grooves, produced through plastic indentation in the metal, serve both as lubricant reservoir and debris removal means. The FriCSo lapping, done with polymer and abrasive paste, produces low roughness area, thin densified layer and increased surface participation in the contact area. In repeated tests and experiments, CMR was found to be highly effective in addressing extreme lubrication conditions such as oil starvation, boundary and mixed lubrication. CMR application results include reduction of friction and superior resistance to scuffing wear and seizure.
