Plating Technology for Contact Joint Performance Improvement in Electrical Equipment

Abstract

The paper analyzes a technology allowing the improvement of such performance characteristics of contact joints as reliability and operating economy, with demountable contact joints taken as an example. The performance characteristics are improved through applying protective metal coatings based on low-melting alloys on the contact members working surfaces. The paper describes the process of alloys selection as well as the development in the technology of the material application onto the contact members.
