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

Patent number: 9518308Abstract: The synthesis of high performance WC-Co cemented carbides which can be efficiently used in the cutting tool industry. WC with different particle sizes and different grain growth inhibitors were consolidated through spark plasma sintering technique and to form a cemented carbide with best combination of mechanical properties. VC and Cr3C2 are included as grain growth inhibitors in different amounts and combination to the WC-Co powder composition. Higher amount of inhibitors results in lower grain sizes and higher hardness values, however adding more than a crucial amount was observed to degrade the mechanical properties.Type: GrantFiled: December 23, 2013Date of Patent: December 13, 2016Assignee: King Fahd University of Petroleum and MineralsInventors: Khwaja Mohammad, Nouari Saheb, Tahar Laoui, Nasser Al-Aqeeli

Patent number: 9296913Abstract: The recycled crumb rubber coating is a corrosion-proof coating for piping and the like. The coating is formed from recycled crumb rubber mixed with an epoxy resin and a hardener. Crumb rubber is first mixed with a liquid epoxy resin. An agent for reducing the viscosity of the liquid epoxy resin may also be added. A hardener is then added to this mixture. Finally, powdered crumb rubber is added and mixed to form the recycled crumb rubber coating. The total crumb rubber forms about 23-24 wt % of the coating, the balance being epoxy. The epoxy has liquid epoxy resin and a hardener in a ratio of about 2:1 by weight. The epoxy may also include a viscosity reducing agent of about 1% of the total weight of the liquid resin and the hardener. The crumb rubber may be a blend of powdered crumb rubber and mesh crumb rubber.Type: GrantFiled: July 7, 2014Date of Patent: March 29, 2016Assignee: King Fahd University of Petroleum and MineralsInventors: Nasser Al-Aqeeli, Hamoud M.

Patent number: 9199310Abstract: The systems and methods of this patent application are directed to producing a composition of nano-grained NiTi (Ni—nickel, Ti—titanium) alloy for use in producing nano-grained wires. Nano-grained wires, for example, are used to generate medical instruments such as an endodontic instrument. A specific method of producing the nano-grained composition includes preparing a mixture of nickel (Ni) powder and titanium (Ti) powder. The mixture of nickel powder and titanium powder is sintered to produce a nano-grained NiTi alloy. In one embodiment, an endodontic instrument is formed using the nano-grained NiTi alloy and heat-treated.Type: GrantFiled: June 9, 2011Date of Patent: December 1, 2015Assignee: King Saud UniversityInventors: Dina Ibrahim Al-Sudani, Nasser Al-Aqeeli, Gianluca Gambarini

Publication number: 20150252451Abstract: The high performance aluminum nanocomposites are formed by a combination of mechanical alloying and Spark Plasma Sintering (SPS) in order to obtain reinforced nanostrutured aluminum alloys, The nanocomposites are formed from aluminum metal reinforced with silicon carbide (SiC) particulates, wherein the SiC particulates have a particle diameter between about 20 and 40 nm. The nanocomposites are prepared by mixing aluminum-based metal, e.g., Al-7Si-0.3Mg, (Al=92.7%, Si-7% and Mg=0.3%), with SiC nanoparticles in a conventional mill to form a uniformly distributed powder, which is then sintered at a temperature of about 500° C. for a period up to about 20 hours to consolidate the silicon carbide particulates in order to obtain the reinforced aluminum metal-based silicon carbide nanocomposite.Type: ApplicationFiled: March 5, 2014Publication date: September 10, 2015Applicant: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: NASSER AL-AQEELI, KACHALLA ABDULLAHI, TAHAR LAOUI, NOUARI SAHEB
