Abstract
Disclosed herein are solid-liquid bi-phase lubricating devices that can include a cuboidal shaped stick with at-least one cylindrical or cuboidal shaped hollow core running through entire or partial length of the stick. The cuboidal shaped stick can include a solid polymer-based composite while the inner space is filled with a semi-fluid grease lubricant. The solid polymer-based composite can include one or more polymers, filler materials, corrosion inhibitors, plasticizers, and additives. The grease lubricant can include lithium, lithium-complex, aluminum-complex, calcium-sulphonate complex, bentone-thickened grease, and mixtures thereof and have an NLGI consistency grade≥1. The lubricating devices can be used for friction reduction of mechanical components involving two or more contacting surfaces in relative motion, such as a steel wheel flange-rail contact interface of transit and freight rail transport systems.
