Tribological behavior of composite-steel on rolling/sliding contacts for various loads

---

Abstract

Composites have replaced metals in the bearing industry for the exclusive performances from itsproperties were it can accommodate resins, fabrics and additives. Roll-slip is common behaviors inapplication were non-conformal contact exhibits like bearings, rollers and cams. Two elements control thetribological behavior of the material which is the rolling and the sliding element. Composite-steel contactswere tested using a twin-disc setup with open tribo-system to study the influence of load on the frictionalbehavior of the polymer composites. The contacts were tested with four different loads under 20% slip ratiofor a regular interval of time. The curves from the friction force with respect to different loads follows atendency of linear increase in friction force were the rolling resistance is the dominating mechanism. For thegiven condition the macro level investigations shows the absence of transfer layer on the steelcounterparts. The tendency of the friction curve and the micrograph explicitly deliberates the involvement ofabrasion and adhesion in the harder polymer from metal counterpart. The temperature variable is isolatedin case of the above research. The examination of the contact surface reveals the formation of craters onthe junction of polymer and textile.
