AB  - Ti-6Al-4V Gyroid triply periodic minimal surface (TPMS) lattices were 
      manufactured by selective laser melting (SLM). The as-built Ti-6Al-4V lattices 
      exhibit an out-of-equilibrium microstructure with very fine alpha' martensitic laths. 
      When subjected to the heat treatment of 1050 degrees C for 4h followed by furnace 
      cooling, the lattices show a homogenous and equilibrium lamellar alpha+beta 
      microstructure with less dislocation and crystallographic defects compared with 
      the as-built alpha' martensite. The as-built lattices present very rough strut 
      surfaces bonded with plenty of partially melted metal particles. The sand 
      blasting nearly removed all the bonded metal particles, but created many tiny 
      cracks. The HCl etching eliminated these tiny cracks, and subsequent NaOH etching 
      resulted in many small and shallow micro-pits and develops a sodium titanate 
      hydrogel layer on the surfaces of the lattices. When soaked in simulated body 
      fluid (SBF), the Ti-6Al-4V TPMS lattices were covered with a compact and 
      homogeneous biomimetic hydroxyapatite (HA) layer. This work proposes a new method 
      for making Ti-6Al-4V TPMS lattices with a homogenous and equilibrium 
      microstructure and biomimetic HA coating, which show both tough and bioactive 
      characteristics and can be promising materials usable as bone substitutes.
