摘要

为提高高温合金的工作温度

一般在其表面涂覆由粘结过渡层和陶瓷隔热层构成的热障层。热障层的热稳定性决定了高温合金部件的寿命。为延长由部分稳定的ZrO2/NiCoCrAlY合金构成的热障层的服役寿命

采用强脉冲离子束对它们的界面进行辐照处理。本工作研究了不同参数的强脉冲离子束（IPIB）对不同厚度结构的靶的辐照混合效应

通过一系列分析测试研究

发现合适参数的IPIB辐照能够有效地在界面形成混合层

从而改善热障层在高温氧化环境中的高温耐久性。其中采用峰值能量300keV

脉冲宽度65ns

峰值流强密度250A/cm2的IPIB单脉冲辐照后的样品获得最好效果。对其原因做了分析

认为在界面处形成特定元素分布的混合层在高温氧化条件下既能形成完整的保护层

又改善了层间晶格和热胀系数失配

减小了失配热应力

从而提高了热障层在高温氧化条件下的稳定性。

Abstract

Thermal barrier coating (TBC) is used for enhancing the working temperature of high temperature alloys. Its thermal stability directly decides service life of the high temperature parts protected by TBC. In this work

intense pulsed ion beam (IPIB) irradiation was used to obtain stability-improved TBC of ZrO2/NiCoCrAlY layers. The IPIB irradiation with proper parameters could form a mixing layer at the interface of ZrO2/NiCoCrAlY with improved thermal stability. The best TBC could be formed under the following IPIB parameters: peak energy of 300keV

pulse duration of 65ns

and current density of 250A/cm2. We owe the enhanced thermal stability of the TBC to the IPIB-induced elemental re-distribution

hence a protection layer under the thermal oxidation working condition

with reduced mismatch and stress between the layers.
