Аннотация

A method of estimating the extent of passivation of iron nanopowders based on color high-speed filming is suggested. It is established that the number of primary centers of combustion and the time of their emergence depend on the passivation time: the more the passivation time is, the lower the number of primary centers of combustion is. This allows using the dependence for estimating both the extent of passivation and the minimum time of complete passivation. A method for calculating the time of complete passivation for the sample of arbitrary thickness is suggested.
