Abstract

The influence of centrifugation on combustion of gasless systems was first studied by Serkov, Maksimov and Merzhanov in 1968.1 Centrifugal acceleration up to 900 g could cause a six-fold increase in the combustion velocity in a thermit system. Further experimental2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 and theoretical17, 18, 19, 20, 21, 22 studies by the present authors and their colleagues showed that gravity exerts a significant influence on chemical conversion in combustion waves, the product-phase composition, and macro- and micro-structures in a wide range of thermit and elemental systems. Use of centrifugal SHS helped to solve such practical problems as production of protective coatings, tubular articles, gradient materials and the like from refractory inorganic compounds and hard alloys.22, 23, 24, 25, 26, 27, 28, 29 The influence of gravity on the SHS processes is being intensely studied in Japan, USA, Italy, China, and others.28-34
