Abstract

Abstract: In recent few years, the environmental issues especially related to the aquatic life are pushing the Friction Industry to develop NAO FMs (non-asbestos organic friction materials) without Cu. Stainless-steel swarf (SSS) having good corrosion resistance was tried as one of the replacing ingredients for Cu in FMs in Authors' laboratory in earlier work. It proved to have a great potential for Cu replacement almost in all the performance properties but at the cost of slightly lower wear resistance and hence the theme of current research was to enhance the wear resistance capability of SSS. Hence, in the present study SSS were treated with air-plasma and used in brake-pads. Thus, two types of brake-pads with the identical composition but differing in type of SSS 10 wt % (treated and untreated) were tribo-evaluated on a full-scale brake inertia dynamometer and treated SSS containing pads exhibited higher wear resistance (approx. 10%) confirming success of the treatment, first time explored for the friction materials. Enhanced adhesion with resin was the main cause for the improved tribo-performance. Highlights: Exploration of plasma treated Stainless-steel swarf (SSS) for application in Cu-free brake-pads is first time reported. Comparative study of impact of untreated and plasma treated SSS on tribo-performance of brake-pads is first time reported. Plasma treatment of SSS proved beneficial for reduction in wear of brake pads.
