Present work deals with understanding the Biodegradability of polymers which are coated with the bio-active coating materials like Al2O3, egg and sea shell powder. The polymers are coated with Plasma spray deposition to ensure proper coating thickness and also to maintain phase purity of powder samples. The powders which were used to prepare coating materials were derived from natural sources like Aluminium oxide, egg shells and sea shells. The extracts are sources of calcium, fibres etc. and hence the coating materials are naturally bio-active and biocompatible. Bio-active coating on Bio-implants are very essential to improve the life span of Bio-implant and also resulted in improvement of hydrophobic properties of Bio-implants. During the biodegradability test it was found that sample polymers coated with sea shell and egg shell yielded better results compared to uncoated materials and also few combinations have shown excellent results in comparison with Hydroxyapatite. The outcomes of the test also proved improved hydrophobic properties of coated polymers.
