【摘要】 本文以ZW-100热障涂层为例,分析该涂层在加热、冷却循环条件下的失效方式,确定应力是导致涂层失效的主要因素,建立应力与疲劳极限之间的关系,得到寿命预测模型,并通过实验验证结果,最后进行试验结果的误差分析。该论文为热障涂层的寿命预测提供一种很好的方法。更多还原

【Abstract】 The paper takes ZW-100 TBC as an example, analyses the failure mode of thermal barrier coating in heating 、cooling cycle condition, confirms the stress is the main factor caused coating failure, establishes the relationship between stress and fatigue limit, obtains the life prediction mode, as well as tests the results through the experiment, finally, carries on the error analysis of experimental result. The paper supplies a very good method for the life prediction of TBC.更多还原
