Abstract:

The poly methyl methacrylate (PMMA) powder was used to prepare bio-composite coating layers by dry electrostatic spray method on stainless steel (SS) 316L as a substrate. Different weight percentages (wt%) of dry powders were mixed to form a composite mixture consisted of (5, 10, 15, and 20) wt% Al2O3 and TiO2 with (95, 90, 85, and 80) wt% of PMMA as matrix material. The ceramic powder additives were studied in Four Groups: (A, B, C, and D). The morphology, particle size, chemical compositions, micro-hardness, adhesion strength, ion release behavior, FTIR, and DSC tests of the polymer composite coating layers were characterized.
