Publication number: 20240102195Abstract: A method of coating a metallic substrate includes immersing a metallic substrate in a polymer composition including a conductive 3,4-ethylene dioxythiophene (EDOT) polymer, a gelatin polyelectrolyte, an antibacterial drug, an organic solvent, and an inorganic salt solute, and further coating the polymer composition onto a surface of the metallic substrate by cyclic voltammetry to form a coating on the surface of the metallic substrate. The coating on the metallic substrate is performed such that the gelatin and the antibacterial drug are uniformly distributed throughout the coating, and the coating has a thickness between 7.0 and 15.0 micrometers. The metallic substrate is a stainless steel (SS). An implantable medical device including a metallic substrate coated by the present method.Type: ApplicationFiled: September 22, 2022Publication date: March 28, 2024Applicant: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Arumugam Madhan KUMAR, Mohamed Abdrabou HUSSEIN

Patent number: 11692242Abstract: A method for producing a biodegradable magnesium metal composite that includes a polycrystalline magnesium matrix and TiB2 grains which are homogenously distributed in the polycrystalline magnesium matrix involving spark plasma sintering a milled mixture of magnesium powder and TiB2 powder. The temperature, pressure, and time of the spark plasma sintering used in the method are used to give high microharness, macrohardness, and density with low porosity by limiting the grain growth in the composite. The method yields a biodegradable magnesium metal composite having an improved microhardness, macrohardness, density, and porosity compared to other composites and methods of making composites.Type: GrantFiled: November 4, 2019Date of Patent: July 4, 2023Assignee: King Fahd University of Petroleum and MineralsInventors: Mohamed Abdrabou Hussein, Murad Ali, Nasser Al-Aqeeli

Patent number: 11433422Abstract: A biocompatible polymer hybrid nanocomposite coating on a surface of a substrate, such as titanium and its alloys. The coating can be achieved by an electrostatic spray coating, preferably using ultra-high molecular weight polyethylene (UHMWPE) as a matrix for the coating. For example, up to 2.95 wt. % carbon nanotubes can be used as reinforcement, as can up to 4.95 wt. % hydroxyapatite. A dispersion of CNTs and HA in the coating is substantially uniform. The tribological performance of such coatings include high hardness, improved scratch resistance, excellent wear resistance, and corrosion resistance compared to pure UHMWPE coatings.Type: GrantFiled: September 12, 2019Date of Patent: September 6, 2022Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Zahid Ahmed Uwais, Abdul Samad Mohammed, Madhan Kumar, Mohamed Abdrabou Hussein, Nasser Al-Aqeeli
