Patent number: 8399103Abstract: A method of a pre-treatment process for coating notably improves both the surface roughness of a coating layer of a cemented carbide cutting tool and the bonding force of the coating layer to the substrate. According to the method, a sintered surface layer within a range of 0.5-5 ?m, which corresponds to the tungsten carbide particle size of a substrate, is properly removed from the substrate surface of a cemented carbide cutting tool.

In order to obtain a sufficient bonding force between a coating layer and the substrate, the surface ratio of open pores, which exist around tungsten carbide particles appearing by removal of the porous sintered surface, is equal to or more than 5%.Type: GrantFiled: April 27, 2007Date of Patent: March 19, 2013Assignee: TaeguTec, Ltd.Inventors: Dong Gil Ahn, Kern Woo Lee

Publication number: 20110111128Abstract: A diffuser structure and a manufacturing method thereof are disclosed. The diffuser structure includes a substrate, a plurality of throughholes, and a glue layer. The throughholes are perpendicularly formed in the substrate. Each throughhole includes a gas-in part, a gas-out part, and a connecting part for connecting the gas-in part to the gas-out part. The glue layer is formed on a side wall of each gas-out part, and a thickness of the glue layer is between 1 ?m and 11 ?m. The present invention can solve a problem that particles are periodically generated after a periodic self-cleaning function is implemented in a plasma-enhanced chemical vapor deposition system.Type: ApplicationFiled: April 18, 2010Publication date: May 12, 2011Applicant: Global Material Science CO., LTD.Inventors: BYUNG-JUN PARK, Jin-jong Su, Fang-yu Liu
