The purpose of this paper is to evaluate the characteristics corrosion protection stainless steel substrates coated with silica by electrophoresis pulsed direct current (PDC) and constant (CDC) anodization. Electrophoresis was carried out using sol from sodium silicate solution as an electrolyte solution. Stainless functioned anode carbon a cathode electrode distance 2 cm. amplitude, duty cycle...

Hydroxyapatite (HA) has been used in clinical bone graft procedures for the past 25 years. Although a biocompatible material, its poor adhesion strength to substrate makes it unsuitable for major loadbearing devices. Investigations on various deposition techniques of HA coating on Ti–6Al–4V implants have been made over the years, in particular to improve its adhesion strength to the metal alloy...
