The test results show that retardation of thermal shock crack initiation and propagation and higher thermal shock resistance property were displayed in graded thermal barrier coating.

实验结果表明，梯度热障涂层能明显延缓热震裂纹的形成和扩展，具有较高的抗热震性。

While the coating deposited by plasma spraying cracked and spalled primarily after endured 3 times thermal shock, which showed that HVOF coating had the excellent resistance ability to thermal shock.

而等离子喷涂的WC涂层经过3次热震试验后就基本开裂和脱落。这充分说明了HVOF涂层具有非常高的抗热疲劳性能。
