Patent number: 10287670Abstract: A low friction top coat over a multilayer metal/ceramic bondcoat provides a conductive substrate, such as a rotary tool, with wear resistance and corrosion resistance. The top coat further provides low friction and anti-stickiness as well as high compressive stress. The high compressive stress provided by the top coat protects against degradation of the tool due to abrasion and torsional and cyclic fatigue. Substrate temperature is strictly controlled during the coating process to preserve the bulk properties of the substrate and the coating. The described coating process is particularly useful when applied to shape memory alloys.Type: GrantFiled: April 16, 2018Date of Patent: May 14, 2019Assignee: G & H Technologies, LLCInventors: Vladimir Gorokhovsky, Brad B.

Patent number: 8658010Abstract: An apparatus for the application of coatings in a vacuum comprising a plasma duct surrounded by a magnetic deflecting system communicating with a first plasma source and a coating chamber in which a substrate holder is arranged off of an optical axis of the plasma source, has at least one deflecting electrode mounted on one or more walls of the plasma duct. In one embodiment an isolated repelling or repelling electrode is positioned in the plasma duct downstream of the deflecting electrode where the tangential component of a deflecting magnetic field is strongest, connected to the positive pole of a current source which allows the isolated electrode current to be varied independently and increased above the level of the anode current. The deflecting electrode may serve as a getter pump to improve pumping efficiency and divert metal ions from the plasma flow.Type: GrantFiled: January 28, 2010Date of Patent: February 25, 2014Assignee: G & H Technologies, LLCInventor: Vladimir Gorokhovsky

Patent number: 6929727Abstract: The invention provides an arc coating apparatus having a steering magnetic field source comprising steering conductors disposed along the short sides of a rectangular target behind the target, and a magnetic focusing system disposed along the long sides of the target in front of the target which confines the flow of plasma between magnetic fields generated on opposite long sides of the target. The plasma focusing system can be used to deflect the plasma flow off of the working axis of the cathode. Each steering conductor can be controlled independently. In a further embodiment, electrically independent steering conductors are disposed along opposite long sides of the cathode plate, and by selectively varying a current through one conductor, the path of the arc spot shifts to widen an erosion corridor. The invention also provides a plurality of internal anodes, and optionally a surrounding anode for deflecting the plasma flow and preserving a high ionization level of the plasma.Type: GrantFiled: September 18, 2003Date of Patent: August 16, 2005Assignee: G & H Technologies, LLCInventor: Vladimir I.

Patent number: 6722883Abstract: A protective coating applied to abrasive layers of polycrystalline diamond located at the tip of abrasive dental tools is described. The protective coating is provided to protect the polycrystalline diamond layers in the course of storage, packaging, handling and sterilization. The protective coating is removable by abrasive forces when the cutting surfaces come into contact with porcelain and hard ceramic dental materials, teeth, bone or similar hard materials, and subsequently, the broken protective coating is rolled back and collected in the crevices and gaps of the polycrystalline diamond layer. The protective encapsulating coating can be made of a tough high melting point polymer layer, or a layer of a tough polymer also containing fine ceramic particles, or of a relatively soft, oxidation resistant metal or alloy.Type: GrantFiled: November 8, 2001Date of Patent: April 20, 2004Assignee: G & H Technologies LLCInventor: Vladimir Gorokhovsky
