dc.description.abstract1The paper investigates the influence of a dispersed filler on the wear resistance and mechanical properties of polymer gas-flame coatings based on the epoxy powder paint P-EP-219. A-glass powder obtained from production waste was used as a dispersed filler in the amount of 5–30%. Optimization of the powder composition and spraying parameters was carried out using the Box–Wilson experimental design method. The coating wear percentage, determined by mass loss, was adopted as the optimization criterion. Tribological tests were performed under sliding friction conditions without lubrication and under limited lubrication with MC-10 grease. It was established that the introduction of 5–20% A-glass into the P-EP-219 powder significantly improves the tribotechnical characteristics of the coatings due to a reduction in the actual contact area, a decrease in the adhesive component of the friction force, and improved heat removal from the friction zone. A further increase in the filler content up to 30% does not lead to a decrease in the friction coefficient and is accompanied by increased brittleness and reduced adhesion strength of the coating to the substrate. Compared with cast bronze BrO-10, dispersion-filled glass–polymer gas-flame coatings exhibit a 1.6-times lower friction coefficient and almost an order of magnitude higher wear resistance, with less damage to the counterbody. The optimal A-glass content was found to be 10 ± 3%, providing a rational combination of high wear resistance and sufficient mechanical strength of the coating. The obtained results make it possible to recommend the optimized dispersion-filled polymer gas-flame coating based on P-EP-219 for industrial application.
