Resumo
The chemical and electrochemical behaviour of the Ti-15V-3Cr-3Sn-3Al alloy in Kroll reagent has been studied after ageing at 350-600°C, to optimise metallographic etching. Etching tests and polarisation curves showed that samples aged at higher temperatures have been more susceptible to corrosion. It has been attributed to the formation of intra- and intergranular α-phase precipitates during ageing.
