摘要: Abstract Electrochemical measurements were performed to investigate the corrosion behavior of Ti-6Al-4 V alloy prepared by selective laser melting (SLM) and commercial Grade 5 sample for comparison. results showed that SLM-produced possesses poorer resistance than sample. Microstructure studies suggested is composed dominant acicular α’ martensite some prior β grains, unlike typical α  +  microstructure in The unfavorable related considerably large amount ’ less –Ti phase compared
