After the committee recorded their observations on the thesis, which were distributed between explanations, corrections, and the student's defense of her thesis, and after the conclusion of the defense, the committee convened to evaluate the thesis. They decided to award the student a Ph.D. degree with a satisfactory grade.
Abstract:
The study aimed to produce titanium and chromium cobalt alloys using silicon and niobium as 5% alloying elements by powder metallurgy for implants in orthopaedic applications. These alloys were coated by a multi-flame thermal spraying process using two different types of Nano coating (Type A: 75% hydroxyapatite + 25% silicon carbide), (Type B: 75% zeolite + 25% zirconia). Surface characterization, mechanical, chemical and biological properties were performed for each sample. The best results were achieved after adding alloying elements and coating them with Nano-coating.
