Iranian Researchers Modify Adhesive Properties of Nanocoating

Tehran, Iran | Posted on September 16th, 2012

This plan can be used directly or indirectly in medical engineering and biomaterials industries.

Hydroxyapatite coating on titanium sub-layer doesn't acquire the necessary adhesive strength in order to be used for medical purposes. The main problem is caused during the sintering of hydroxyapatite (HA). High temperature of sintering (higher than 1200 °C) erodes the sub-layer metal and also results in the decomposition of hydroxyapatite.

The most important objectives of the research were to modify the adhesive and corrosive properties of hydroxyapatite nanocoatings by improving Ti-6Al-4V sub-layers through wire-brushing method.

"Hydroxyapatite nanoparticles were synthesized in this research with particle average size of 65 nm through chemical deposition method," Hamid Reza Farnoush said, elaborating on the results of the research.

"Adhesive strength was calculated to be around 24 MPa for the electrophoretic coating of hydroxyapatite nanoparticles on the modified Ti-6Al-V sub-layer. The value was almost twice the value of the sample without brushing pre-preparation. Results obtained from the corrosion test on the coated sample on the brushed surface showed noticeable reduction in the corrosion current density and corrosion rate while they showed increase in the corrosion potential and polarization resistance."

Results of the research have been published in August 2012 in the Ceramics International magazine, vol. 38, issue 6, pp. 4885-4893.
