Pyrometry of the processes of self-propagating high-temperature synthesis

Abstract

The developed method of luminance pyrometry used for temperature measurement in processes of self-propagating high-temperature synthesis, plasmathermal spraying of both moving and motionless media has been described. MIS photodiodes operating in direct detection mode or charge accumulation are sensitive elements of optoelectronic track of the device. Change of light signal intensity created by surface of reacting substances is recorded in two microareas. Research results of temperature, distribution speed of combustion front from time and quantitative content of titanium carbide in a batch as well as hardness of sintered samples of the Fe2O3, Al+TiC system are given
