Abstract
The present work aims to prepare polymer-based biocomposite coated layers by electrostatic spray method onto a 316L stainless steel substrate. Different percentages of ( 2,4, and 8) wt.% of Hydroxyapatite (HA) with (98,96, and92) wt.% of PMMA were used to prepare the composite coating. Wettability, phase composition, and surface morphology were studied using contact angle measurement, X-ray diffraction, and scanning electron microscopy techniques respectively. The results revealed that a homogenous, uniform, and crack-free coating layers were obtained. The wettability testing indicated increased hydrophobicity of the coatings with the addition of hydroxyapatite particles where the 8wt.%HA applied the highest contact angle of (104.08o).The average thickness was about (400µm) for the coating layer deposited on the substrates using the electrostatic technique, whereas the average diameter coating was about (33.95µm).
