Structure of aluminum powder coatings prepared by cold gasdynamic spraying

The method of cold gasdynamic spraying has been developed at the Institute of Theoretical and Applied Mechanics of the Siberian Branch of the Russian Academy of Sciences. This form of spray-coating is implemented in a special installation in which powder particles are accelerated by an air jet to a supersonic speed, bombard the substrate, and form a coating layer on it. The present work concerns the structure of a coating of aluminum powder deposited on steel SO.Translated from Metallovedenie i Termicheskaya Obrabotka Metallov, No. 3, pp. 36–39, March, 1996.
