Electrophoretic deposition of magnesium silicates on titanium implants: Ion migration and silicide interfaces

- Decomposition behavior greatly differs in magnesium silicate coating and bulk.
- Coatings transform into MgO nanowires at relatively low temperatures as compared to the bulk.
- Annealing of non-stoichiometric samples to form forsterite improves thermal stability.
- A titanium-rich silicide layer forms at the ceramic-metal interface due to ion exchange.
- Unlike calcium phosphates, low thermal mismatch avoids formation of microcracks.
