Document Type and Number:
Japanese Patent JP6957963
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a determination method of an adhesion state capable of simply evaluating the quality of the adhesion state between a metallic material and a rubber material.SOLUTION: A determination method of an adherence state is the method for determining the adherence state between a metallic material and a rubber material covering the metallic material. The metallic material has a plated layer mainly comprising brass or zinc on a surface layer. In this method, an amount of cobalt is calculated, which exists inside the rubber material on an inner surface of the rubber material exposed in the vicinity of an interface located along the interface spaced away from the interface of the metallic material. When the amount of cobalt of the surface of the metallic material is greater than the amount of cobalt of the inner surface of the rubber material, it is determined that the adherence between the metallic material and the rubber material is excellent.SELECTED DRAWING: Figure 3
