  • Spark plasma sintered cBN and Ni-cBN bearing steel
    Patent number: 11707784
    Abstract: Bearing steel comprising cubic boron nitride (c-BN) and/or nickel coated cBN spark plasma sintered at a temperature in the range of 850-1050° C. is disclosed. The tribological and corrosion resistance of the bearing steel improved with increasing the amount of c-BN. Further improvement in the properties was achieved with the incorporation of nickel coated c-BN, which caused a phase transition of the bearing steel from magnetic to non-magnetic phase accompanied by interdiffusion enhancement between the matrix and c-BN reinforcement.
    Type: Grant
    Filed: October 15, 2019
    Date of Patent: July 25, 2023
    Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALS

  • Method of making UHMWPE hybrid nanocomposite coating reinforced with nanoclay and carbon nanotubes
    Patent number: 11401436
    Abstract: A method for forming a nanocomposite coating on a substrate is described. The nanocomposite substrate comprises polyethylene, functionalized carbon nanotubes, and nanoclay. The method may use microparticles of UHMWPE with functionalized carbon nanotubes and clay nanoplatelets to form a powder mixture, which is then applied to a heated substrate to form the nanocomposite coating. The nanocomposite coating may have a Vickers hardness of 10.5-12.5 HV and a debonding strength of at least 25 N.
