Abstract
The paper studies the influence of the interelectrode medium and electric spark processing (EDT) modes on the microhardness, structure and tribological properties of the modified surface layers formed under various technological modes. The following esters were used as the interelectrode medium: DOS is the dioctyl sebacate (an ester of isooctyl alcohol (2-ethylhexanol) and sebacic acid) and DOP is the dioctyl phthalate (a diester of phthalic acid and 2-ethylhexanol), which have a complex branched structure and high-energy release during decomposition. The pulse period (T, μs) and pulse duration (t, μs), as well as their combination - the duty cycle of the pulses, were considered as controlled technological parameters. Analysis of the conducted studies shows the effectiveness of using ESA in the interelectrode media under consideration for coatings of heavily loaded tribosystems.
