  • Surface modification process on metal dentures, products produced thereby, and the incorporated system thereof
    Patent number: 7002096
    Abstract: Metal and/or partial metal dentures having a surface modified by a pulsed electron beam system. The system includes an explosive emission cathode, an accelerating gap formed by the cathode and plasma anode, and an electron collector where the metal and/or partial metal dentures are fixed, and placed into a magnetic field. The surface of the modified metal and/or partial metal denture has high reflectance like a mirror polished surface and high corrosion resistance.
    Type: Grant

  • Diamond-like carbon thin film coating process
    Patent number: 6753042
    Abstract: Wear-resistant and low-friction hard amorphous, diamond-like carbon coating (DLC) is formed directly on an eternal surface of a magnetic recording media sensor (MRMS). The coating demonstrates a high degree of hardness, low friction coefficient and moderate electric resistivity, providing abrasion-proof, low-clogging, static electricity-deterrent properties.
