Abstract
Description
technical field
[0001] The invention relates to a component analysis technology of an electromagnetic relay contact, in particular to a method for superimposing and fusing components of the contact surface of an electromagnetic relay. Background technique
[0002] The core component of the relay is the contact, and the change of the surface composition of the contact directly affects the life and reliability of the relay. In order to ensure accurate evaluation of the use status of the relay, it is necessary to study the surface morphology of the relay contacts. Many scholars at home and abroad reflect the shape change of the contact through the roughness of the contact surface, but they cannot directly reflect the change of the contact surface, which brings great difficulties to the reliability and life evaluation of the relay.
[0003] The current evaluation of the relay contact surface is mainly based on the quality change of the contact surface or the change of the conta...
