Cell viability and collagen deposition on hydroxyapatite coatings formed on pretreated substrates

A method of thermal deposition that involves localized high peak temperatures at the electrode-electrolyte interface was proposed for hydroxyapatite (HA) coatings deposition. Active surface layers were obtained by HA incorporation from the aqueous electrolyte into the substrate surface due to the decrease of HA solubility with increasing of substrate temperature. Commercially Ti-6Al-4V alloy (grade 4) substrates were pretreated by sandblasting...
