A burner heating test system for evaluating thermal shock behavior of Functionally Graded Materials (FGM) has been developed, which has well-combined automatic and multi-functions. Thermomechanical properties of a FGM specimen can be systematically investigated by heating the ceramic surface with burner flame and coolong the bottom surface (usually metals) with gas or water flow in the newly developed system. The top and bottom surface temperatures and the average heat flux were determined as a function of the power output of burner. Thermal shock damage was monitored with acoustic emission signals liberated from damage initiation and propagation. By increasing the output power of burner stepwisely, a cycle of heating and cooling was repeated until a large damage was detected.The burner heating tests have been carried out for evaluating the thermomechanical performance of Functionally Graded Materials (FGMs) fabricated by powder metallurgical process, such as in the SiC-A1N/Mo, A1N/W,PSZ/Stainless steel systems. It has been clarified that the properties including thermal shock resistance and thermal insulation, which is needed for the design of the FGM materials, can be determined using the developed system.

已经开发了用于评估功能分级材料（FGM）热冲击行为的燃烧器加热测试系统，该系统具有完善的自动和多功能。可以通过用燃烧器火焰加热陶瓷表面并在新开发的系统中使用气体或水流冷却陶瓷表面，并冷却陶瓷表面，并冷却陶瓷表面，可以系统地研究FGM试样的热力学特性。顶部和底部表面温度和平均热通量是燃烧器功率输出的函数确定的。通过从损坏开始和传播中释放出的声发射信号来监测热休克损伤。通过增加燃烧器的输出功率，重复加热和冷却的循环直到检测到大损坏为止。燃烧器加热测试已进行，以评估由粉末冶金过程，冶金过程，粉状分级材料（FGM）的热机械性能，例如在SIC-A1N/MO，A1N/W，PSZ/不锈钢系统中。已经澄清的是，可以使用已开发的系统确定包括热冲击性和热隔热的特性，这是FGM材料设计所需的。
