Method of making a multi-elemental electrical contact brush. |
摘要 |
<p>Graphite particles as small as 38 microns are cleaned, dried and chemically plated with copper or silver. One or multiple chemical platings may be carried out to provide a uniform and thick metal coating. The plated powders are dried and then molded into a desired shape under heavy pressure in a hydraulic press or the like after which the molded shape is sintered under a hydrogen atmosphere for the subsequent fabrication into monolithic or multi-elemental brushes for high-current collectors.</p> |
