ELECTRODEPOSITED DIAMOND BUR WITH DIAMOND COATING FOR GRINDING OF THE DENTAL CERAMIC

摘要

It is designed to provide the service life that electro-deposition diamond bur improves drill bit, the loss of diamond particles is prevented and prevents wearing adhesive layer, when milled ceramic artificial tooth. Realize identical, according to the drill bit for being deposited on metal surface of electro-deposition diamond bur wherein diamond particle and nickel coating, coating has better wearability and non-cohesion, both nickel coating can be seated in, to form triple room electro-deposition. Coating is to be coated with NiP alloy layers in the presence of nickel coating, is electroplated, 20-24 thickness it; M, while Ni-P coating forms the stage that upper layer plating started at average current density 9-11 A/dm^2 11 to 13 minutes, and in average current density 2-3 after end A/dm^2 plating. Because under the conditions of being adjusted to using HFCVD, methane concentration by volume 0.02-0.The pressure of 03 CH4/H2,40 to 50 supports, 750 to 800 & deg; The temperature of the pattern of C, 1900 to 2000 & deg; The filament temperature of C and 5 to 6 hours sedimentation times. Electro-deposition according to the present invention is related to be ground ceramic artificial tooth, and premature wear can prevent from being electroplated, this leads to the method for preventing the service life of early wall losses diamond particles and raising cutter. ;The 2016 of copyright KIPO submissions
