Effect of heat treatment on corrosion behaviour of selective laser melted Ti-6Al-4V alloy in Ringer's solution

Year: 2025

Type: article

Abstract: The additive manufacturing is developing rapidly among the advanced technologies to fabricate the orthopaedic and dental implants with complex shape (e.g. spherical) due to such advantages as high production efficiency and minimal waste of material. Ti-6Al-4V alloy samples were fabricated by the technology of selective laser melting. The effect of a post heat treatment, carried out below the polymorphic transformation temperature, on the microstructure and corrosion behaviour of the alloy was investigated. It was determined that such a heat treatment of the microstructure leads to improving corrosion resistance of Ti-6Al-4V alloy in Ringer's solution due to a growth of the β phase, an decrease of the α' martensite and microstrain in the α/α' lattice. • Ti-6Al-4V alloy samples were manufactured by selective laser melting technology. • Heat treatment led to improving corrosion resistance of alloy in Ringer's solution. • This is associated with growth of β phase and decrease of α' martensite.
