摘要
为使热障涂层与基体有更好的力学和物理性能匹配,探索一种在铝基体中通过摩擦搅拌掺入NiCrA1CoY颗粒和NiCrAlY+ZrO2混合粉粒体进行基体改性的方法。结果表明摩擦搅拌方法可实现颗粒的有效掺入和分布,而处理温度的控制对处理质量具有决定性作用。
In order to better match the mechanical properties and physical properties of thermal barrier coatings with matrices, we explore a method for dispersing NiCrA1Y particles and NiCrAlY + ZrO2 mixed particulates into aluminum matrix using friction-stir processing (FSP). The exploration results show that the FSP can effectively disperse and distribute the particles and that its temperature control is decisive on the quality of thermal barrier coatings.
