RISDesigning a Bioinspired Surface for Improved Wear Resistance and Friction Reduction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study used 2-photon three-dimensional lithographic printing and replica molding to fabricate a micro-texture based on the Ocellated Skink. The fabricated surface texture was studied for friction and wear behavior using ...
Improved Tribological Performance of Polydopamine/Polytetrafluoroethylene Thin Coatings With Silica Nanoparticles Incorporated into the Polydopamine Underlayer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Polytetrafluoroethylene (PTFE) is a solid lubricant with low friction coefficient. However, it lacks durability as a thin coating. Prior studies have shown that a polydopamine (PDA) underlayer enhances the coating durability. ...
Fabrication and Testing of Bioinspired Surface Designs for Friction Reduction at the Piston Ring and Liner Interface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The piston ring and liner interface is a major source of friction loss in automotive combustion engines. This loss can be mitigated by learning from surfaces from nature that manipulate friction. In this study, novel ...
