摘要: A transient comparative exponential method (CEM) was developed to measure the thermal conductivity of thin ceramic coatings based on comparing rate heating during its stage a metal specimen with known capacity without and coating. The experimental results were explained modelling conductive heat transfer within plasma-sprayed porous coating structure taking into account contact barrier resistance (CHBR) between splat boundaries, substrate as well their dependence gas pressure pores microcracks function geometric altitude.
