In the present work we discuss recent studies concerning plasma dynamics influence on the material synthesis product of the impulse plasma deposition process. Conditions favourable for evaluation of the Rayleigh-Taylor instability on the current sheet surface were found during the computational studies of plasma movement in the coaxial accelerator. Appearance of this phenomenon explains non-uniform phase composition and morphology of coatings. By modifying the design of the plasma accelerator, we succeeded in reducing substantially Rayleigh-Taylor instability and in obtaining α-Al_{2} O_{3} coatings instead of common γ-Al_{2}O_{3}.
