Abstract

The powder metallurgical fabrication of a functionally gradient material for thermal barrier use of a specific material combination of SiC-AlN/Mo is described. The results of thermomechanical tests for non-FGM have shown that the samples HIP'ed at 2123K at the pressure of 200MPa for 2h from mixture of SiC and AIN powders have a sufficient thermal barrier property with high fracture strength even at elevated temperature than monolithic SiC and AIN. The designing of the compositional distribution was made on the basis of the calculation of the overall heat transfer in a temperature difference of 1000K. According to the optimum compositional distribution,the sinterd compact of the functionally gradient material of SiC-AlN/Mo was successfully fabricated.
