Abstract
To evaluate the corrosion behavior in simulated body fluid pure and 10wt% 80Al 2 O 3 -20TiO 2 reinforced HA coatings were successfully deposited by atmospheric plasma spray technique on SS-304L substrate alloy. To eliminate non favorable phases on the as sprayed coatings the coatings were heat treated at 700°C and 800°C for post coating heat treatment technique. Both pure and reinforced as sprayed and post coating heat treated coatings were characterized by XRD and SEM/EDAX analysis for surface characterization and further evaluated by electrochemical test for corrosion behavior in simulated body fluids.
