MANUFACTURING PROCESS FOR COMPOSITE MAGNETIC SHEET USING HOT ISOSTATIC PRESSING AND COMPOSITE MAGNETIC SHEER MANUFACTURED BY THIS PROCESS.

摘要

metal powder and flakes (Flake) ready to step into the flake metal powder heat treating, the heat-treated flakes were dispersed metal powder in a binder, the method comprising molding into a sheet, comprising: forming a metal powder into the sealing seat on the wrapping material in a vacuum, a sealed package, said packaging sheet metal powder into a closed container increasing the internal pressure of the closed vessel by introducing an inert gas or air, increasing the temperature in the closed vessel for a high pressure that contains the sealed sheet metal powder phase, containing the metal powder with the sealing sheet step of cooling the high pressure in the sealed vessel, removing the internal pressure of the closed container containing the sealing of the high-pressure metal powder sheet, characterized in that the composite magnetic removal of the packaging material, comprising the step of collecting a sheet The manufacturing method using the sheet. This may solve the problem of non-uniformity of the sheet density and magnetic properties having difficulties binary composite magnetic sheet production process by the conventional magnetic sheet production method of uniaxial pressing. That is, the flake (Flake) heat contact bonding method and degree of orientation of the metal powder to have a cross-correlation, the present invention is the introduction of the isostatic pressing process, an effect to increase the degree of orientation of the flake metal powder. ;
