Processes of Multilayer Coatings Deposition Onto Powder Materials and Equipment for Such Processes

摘要

The paper presents processes of multilayer deposition of refractory and fusible metals and alloys onto powder materials. The paper also presents evaluation of deposition conditions necessary to ensure high thickness uniformity of coating on a single powder particle as well as on entire powder mass. The paper presents experimental results of coating deposition, methods of removal of heat load, powder material transportation, deposition methods, and on-line control of coated material quality. The paper presents example of high-productive vacuum equipment for implementation of powder material coating technology.
