|
In the present study, a simple method was successfully used for hydroxyapatite coatings on Ti-6Al-4V substrates deposited by using a sol-gel derived precursor. Prior to hydroxyapatite coatingthe samples were micropolished (0.1 micron) and divided into three sets. The first set,were themicropolished samples kept as such. The second set were coated with titania sol and the third setwas treated with 5M NaOH. After three repetitions of hydroxyapatite coating procedures on eachset and heat treatment at 600 °?C, the formation of hydroxyapatite has been confirmed by XRDanalyses and the substrate material was found to be oxidized with negligible amount of CaO in thecoating. The SEM studies revealed surface morphology. Hydroxyapatite, calcined at 600°?C,displaying a porous structure arisen from heating of the bulk But, it is very meaningful in trying to approach morale management plans with an object ofdental technicians. It is necessary that dental technicians should make efforts to control themselves.
