Document Type and Number:
WIPO Patent Application WO/2016/047717
Kind Code:
A1
Abstract:
Provided is a method for manufacturing an amorphous alloy core comprising steps for: preparing a laminate that is configured by laminated amorphous alloy strips and has one end surface and another end surface in the width direction of the strips, and an inner peripheral surface and an outer peripheral surface orthogonal to the lamination direction of the strips; forming a hole starting from one end surface of the laminate; heat treating the laminate, after the hole has been formed therein, while measuring the temperature inside the hole; and applying and curing a two-liquid epoxy resin composition that has a viscosity of 38 to 51 Pa・s and a T.I. value of 1.6 to 2.7 onto at least a portion of at least the one end surface of the laminate after the laminate is heat treated, thereby forming a resin layer which coats at least the portion of the one end surface while blocking the hole.
