Abstract

Tribotechnical composites based on epoxy oligomers are used to benefit from special properties of epoxides showing high moldability, adhesion ability, and corrosion resistance and low shrinkage. Epoxy resin ED-20, curing agent polyethylene polyamine, and mineral powder and fibrous fillers are used to form epoxy composite material. Conditions in which friction and wear stabilize through formation of a self-assembled structure are established in tribotechnical tests. The wear rate is studied as a function of speed, load, and friction path. The effectiveness of gradual loading of the composite during tribological interaction is shown. This allowed a wear-resistant surface structure to be created.
