Annotation The effect of the high-voltage supply capacity in the form of different pulse duration on the formation of preferentially oriented crystallites and the stress-strain state of the vacuum-arc TiN coatings was analyzed. It is shown that the deposition of coatings in a high-voltage cascade forming exposure leads to the growth of the crystallites with axis texture [110] and the change in the stress-strain state: strengthening of a strain in a group of crystallites with the axis [110] and reduction of the strain in a group of crystallites with axis [111]. The results are explained by the increase in mobility of atoms and streamlining processes in the field of displacement cascades, formed under the influence of high-energy bombarding ions accelerated in the field of high-voltage pulse potential. A generalized graph of the texture type on the pulse potential and influence of the pulse duration, applied to the substrate, on the total deposition time are plotted.
