Investigation BG/PMMA Composite Coating Using Electrostatic Dry Spray Of Titanium Implant.

The goal of the current work is to prepare coated layers of polymer-based bio composite onto a commercially pure titanium substrate utilizing an electrostatic spray approach. To obtain the coating made of bio composite Different percentages of (2.5,5,7.5, and 10) wt.% of bioactive glass (BG) with (97.5,95,92.5, and100) wt.% of PMMA powder. The coated layers' surface morphology was assessed using FTIR, XRD, and SEM techniques. The coated samples exhibited distinct biological behavior examined using the contact angle test, which demonstrated their good wetting properties the percentage of (10% BG) percent was the lowest angle, which is 18.643, and the percentage of (2.5%BG). was the highest angle 77.697. It was possible to create homogenous, uniform, and crack-free coating layers in addition to a high surface wettability. When the mechanical qualities were assessed using Vickers microhardness, it became clear that the polymeric coating's hardness had increased due to the ceramic particle addition which is 246 HV. Furthermore, the evaluation of scratch hardness was carried out to evaluate the coating's adherence. Where with increasing percentage of BG THE Hardness increased to (14.8835) MPa (10%BG).
