Enhancing the tribological properties of fluoroplastics operating in a hydraulic fluid environment

Abstract

The issues of an increasing the wear resistance of fluoroplastics under conditions of dry friction against steel and in the environment of hydraulic fluids are discussed in this article. The statement about the prospects of radiation treatment for strengthening fluoroplastics is substantiated. Comparative tribological tests were carried out on a laboratory friction machine according to the friction scheme of the end of a cylindrical sample made of steel 40X13 on a fluoroplastic plate. It has been established that radiation-modified fluoroplastic has increased wear resistance. The antifriction properties of strengthened fluoroplastic during friction in a hydraulic fluid environment are investigated. The influence of load and speed on the friction coefficient is analyzed. Based on the study, a radiation modification of fluoroplastic rod seals of hydraulic cylinders and hydraulic piston machines is proposed, with a possible increase in wear resistance up to 4 times.
