This paper discusses the use of epoxy coatings modified with rice husk ash in order to reduce abrasive wear of materials and increase their durability during operation. It was experimentally established that the rice husk ash used as a filler increases the wear resistance and hardness of epoxy coatings with a significant decrease in the coefficient of static friction. This effect occurs when using ash obtained by burning rice husk at various temperatures. It is associated with an increase in the density of the formed spatial network in the presence of the studied filler, due to the selective sorption of the components of the epoxy composition by a developed solid surface.
