| 20110203468 | PRINTING ROLL AND METHOD OF PRODUCING THE SAME - In order to propose a dry process technique of producing a printing roll having safe and beauty concave portions for printing image area without discharging environmental contaminating substance and a new technique for improving quality of printed matters, this invention is to provide a printing roll with DLC film layer in which laser beam-engraved grooves as concave portions for printing image area are formed on a carbide cermet spray coating formed on a surface of a roll substrate, and a method wherein a carbide cermet spray coating is formed on a surface of a roll substrate roughened by a blast treatment, the surface of the carbide cermet spray coating is ground or ground-polished, then a DLC film is formed on the ground or ground-polished surface and thereafter laser beam-engraved grooves are formed on the surface of the DLC film as a concave portion for printing image area. | 08-25-2011 |
| 20100203288 | SPRAY-COATED MEMBER HAVING AN EXCELLENT RESISTANCE TO PLASMA EROSION AND METHOD OF PRODUCING THE SAME - A spray coated member having an excellent resistance to plasma erosion is produced by irradiating an electron beam to an outermost surface layer portion of a ceramic spray coated portion covering a surface of a substrate to form an electron beam irradiated layer. | 08-12-2010 |
| 20090208667 | METHOD FOR MANUFACTURING CERAMIC COVERING MEMBER FOR SEMICONDUCTOR PROCESSING APPARATUS - Producing a ceramic coating member for a semiconductor processing apparatus with a purpose of improving the resistance of members and parts disposed inside of vessels such as semiconductor processing devices for conducting plasma etching treatment in a strong corrosive environment and as a means for solution, forming a porous layer by irradiating an oxide of an element in Group IIIa of the Periodic Table to be coated directly or through an undercoat on the surface of the substrate of a metal or non-metal and further forming a secondary recrystallized layer of the oxide on the porous layer through an irradiation treatment of a high energy such as electron beam and laser beam. | 08-20-2009 |
| 20090120358 | Spray coating member having excellent injury resistance and so on and method for producing the same - For the purpose of solving problems inherent to a white Al | 05-14-2009 |
| 20090080136 | ELECTROSTATIC CHUCK MEMBER - An electrostatic chuck member comprises an electrode layer and an electric insulating layer, wherein a spray coating layer of an oxide of a Group 3A element in the Periodic Table is formed as an outermost layer of the member and a surface of the spray coating layer is rendered into a densified re-melting layer having an average surface roughness (Ra) Of 0.8-3.0 μm. | 03-26-2009 |
| 20080241522 | THERMAL SPRAYING POWDER, THERMAL SPRAY COATING, AND HEARTH ROLL - A thermal spraying powder contains 30 to 50% by mass of chromium carbide with the remainder being an alloy containing chromium, aluminum, yttrium, and at least one of cobalt and nickel. The thermal spraying powder has an average particle size of 20 to 60 μm. The thermal spraying powder may contain 20% by mass or less of yttrium oxide in place of a part of the alloy. A thermal spray coating obtained by thermal spraying of the thermal spraying powder, particularly, a thermal spray coating obtained by high-velocity flame spraying of the thermal spraying powder is suitable for the purpose of a hearth roll. | 10-02-2008 |
