It is necessary to measure the continous variation of thermal conductivity of coatings due to structural changes during ablation, so tests had been carried out under the conditions imitate to practical operation by specimens similar to actual components. The thermal diffusivity a and thermal conductivity k have been calculated in this paper from the temperature increasing curves of the inner and outer surfaces of specimen and the size changing in ablating experiment by arc plasma. It is suggested in this paper that the moving boundary of constant temperature model can be substituted by the fixed boundary of varying temperature model to treat the case with ablation; in the case without ablation, the unknown quantities qc (the heat flow) and k can be cancelled at first by calculating the ratio of temperature increases of the inner and outer surfaces of specimen, and then k and qc can be calculated as the value of a is obtained.

测定涂层热导率在烧蚀过程中因结构改变而不断产生的变化是必要的,因此采用类似实际部件的试样在接近使用情况的环境中进行了试验.本文根据试样在电弧等离子体烧蚀实验中内外表面的升温曲线和尺寸变化计算了材料的热扩散率α和热导率k.本文提出可以用变温不动边界的模型代替恒温移动边界的模型来处理有烧蚀的情况;当试样无烧蚀时,可以先通过计算内外表面的温升比消去未知量q_c(热流)和k,在求得α值后再计算k和q_c.
