Findings from Lulea University of Technology Yields New Data on Friction, Lubrification and Wear (Dry rolling/sliding wear of nanostructured bainite)

August 12, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Fresh data on Friction, Lubrification and Wear are presented in a new report. According to news originating from Lulea, Sweden, by VerticalNews correspondents, research stated, "The abrasive wear of carbide-free bainitic steel under dry rolling/sliding conditions has been studied. It is demonstrated that this nanostructure, generated by isothermal transformation at 200 C, has a resistance to wear that supersedes that of other carbide-free bainitic steels transformed at higher temperatures."

Our news journalists obtained a quote from the research from the Lulea University of Technology, "The experimental results in combination with a theoretical analysis of rolling/sliding indicate that, under the conditions studied, the role of sliding is minimal, so that the maximum shear stresses during contact are generated below the contact surface. Thus, the hardness following testing is found to reach a maximum below the contact surface."

According to the news editors, the research concluded: "The fine scale and associated strength of the structure combats wear during the running-in period, but the volume fraction, stability and morphology of retained austenite play significant roles during wear, by work-hardening the surface through phase transformation into very hard martensite."
