Abstract:
Analysis of the temperature dependence of the emissivity of materials showed that for many materials the dependence of the emissivity on temperature is a linear function. A mathematical model was created with which the parameters of the linear dependence of the emissivity are determined from the experimental cooling curves. The temperature dependence of the emissivity of steel plates is determined, the systems of a steel plates — selectively absorbing coating and a material of selectively absorbing coating based on NiO-TiO$_2$ obtained on a solar furnace.
Keywords:
emissivity, heating, cooling curve, steel plate, selectively absorbing coating, composite material.
