Abstract

This research studies the coating layer properties from chitosan and nano –hydroxyapatite made by pulsed electrophoretic deposition (PEPD) for biomedical applications. The 316L SS alloys were coated with hydroxyapatite in different solutions in 100 mL of suspension at a 30 V continuous voltage. To characterize the deposited coatings, X-ray diffraction spectroscopy (XRD), Fourier transform infrared (FTIR), Contact Angle, scanning electron microscopy (SEM), energy dispersive x-ray analysis (EDX),Yield deposition and Optical microscopy structural (OM) was used for coating layer, in addition to being calculated Zeta potential for suspensions. The aim of this study is to show that using the Pulsed EPD method at room temperature, a simple and low-cost solution for in situ synthesis of Nano -HAp within a chitosan matrix for biomedical applications can be demonstrated.

Highlights

  • Pulsed EPD improved the coating layer by degreasing the bubbles and cracks.
  • Using an FTIR test, major chemical bonds were found to the HAP and CS.
  • Little frequency in the PEPD causes degreasing distortion in the coating layer.
