[ 1 ] - Parametric Optimization of Electro Spark Microwelding of Aluminum Clad Steel (RESEARCH NOTE)

The feasibility and parameters optimization of AA5183 aluminum cladding on AISI 1018 steel by electro spark microwelding (ESM) and the corrosion resistance of the clad plate were investigated. The optimum conditions were found as 15 A, 10%, 800 Hz and 2500 rpm for P, D, F and R factors, respectively. Confirmation test under optimum conditions showed that the model can be effectively used to pre...

[ 2 ] - A Study of Zeta Potential of Plasma Sprayed Hydroxyapatite Coating in Four Simulated Physiological Solutions

The zeta potential magnitude and the duration of its changes have been thought to be directly related to the surface reactivity, the governing of osteoconductivity and availability of valuable information in determining the anticipated in-vivo performance of implants. In this study the zeta potential of plasma sprayed hydroxyapatite (HA) was evaluated in various simulated physiological solution...

[ 3 ] - Interface Characterization of Plasma Sprayed Hydroxyapatite Coat on Ti 6Al 4V

Hydroxyapatite (HA), a material proven to be biocompatible within the human body, has been produced to a high level of purity. This material has been applied as a coating on Ti-6Al-4V alloy by using the air plasma spraying technique. The coat was characterizted with SEM, XRD, FTIR and Raman spectroscopy methods to consist of a mixture of calcium phosphates including HA mainly and traces of tric...
