Essay

It is determined that not only quantitative characteristics of adsorption at the rubbing surface is important for its durability but also its fast composition. Taking the abovementioned into consideration the following antiwear doping agents to drilling fluids: argillous - colloidal graphite, dodgered - modified antifriction graphite, mineralized - cross-linked polyacrylamide, petroleum - soda soap mixtures. Spectrograms of adsorbed films made in infrared band had proved the justice of advanced theories of lubrication.
