Abstract
The paper discusses a method of chemical polishing of Ti6Al4V samples and presents the results of our study. The samples were produced by selective laser melting, which is an increasingly popular method of producing thin-walled, geometrically complex products. The document analyzes how polishing with solutions featuring a varying content of hydrofluoric and nitric acids affects the etching rate and alters the superficial roughness of the samples in both the longitudinal and the transverse directions. We have thus formulated the recommendations on the optimum composition and concentration of such acidic solutions for polishing Ti6Al4V products made by selective laser melting.
