Chemical polishing improves surface roughness of Ti–6Al–3Mo alloy after wire electroerosion cutting, suggesting optimal treatments.
The influence of chemical and electrochemical polishing on the surface roughness of the Ti–6Al–3Mo alloy obtained after wire electroerosion cutting are investigated. After electrochemical polishing in mixtures of perchloric and acetic acids, the surface roughness of the alloy Ra corresponds to 0.8 mkm, but due to the inhomogeneous distribution of the electric field, rounding of the edges and macro-unevenness occurs. The composition of the electrolytes and the modes for chemical polishing of the alloy are recommended. After such treatment, the arithmetic mean of the profile deviations does not exceed 0.6 mkm.
