摘要：

Present study offers the technology for production of small uniform particles and coatings by employment of nonequilibrium plasma at atmospheric pressure. A new process has been developed for a high rate plasma deposition of fine particles from solid carbon, aluminum hydroxide and some other related precursor powder. The SEM micrographs showed the features of synthetized carbon particles injected into plasma jet reactor before and after plasma treatment. Shape and size of these particles strongly depend on the localization of inserting place. Significant differences in size and shape were observed over deposition process when initial carbon powders were feeding directly into the reacting arc zone together with propane-butane gas. The carbon film elements deposited on a quartz substrate with addition of propane-butane showed the minimal size and streamline shape. Visual and SEM observations confirmed that carbon coatings proved to be suitable for further deposition of catalytic and tribological coatings.
