Effect of heat losses from two-layer specimen surface on variation of thermophysical characteristics by pulse technique

Abstract

Analytical solution of thermal conductivity nonstationary problem for two-layer specimen during pulse heating is made and evaluation of determination error of thermophysical characteristics of pulse coating technique due to specimen heat exchange with environment is given on its basis. It is shown that at specimen heating from coating side the error in basis temperature determination linked with an account of basis surface emission at 2073 K coating temperature may reach 41 percent. Thermogram time variation is recommended to be used to determine thermophysical properties.
