Abstract

Al2O3–ZrO2 ceramic coatings were fabricated on titanium alloy substrate by ultrasonic assisted laser cladding. The effects of ultrasonic on the microstructure and mechanical properties of the coatings are investigated through experiments. A novel laser cladding method by ultrasonic assisted is used in this paper. In this method, ultrasonic waves are directly applied on the micro-zone of molten pool. Experimental results indicated that the grain size and mechanical properties of the coatings are improved with the ultrasonic assisted. The amount of coatings cracks are decreased due to the application of ultrasonic vibration in the laser cladding.

超声辅助激光熔覆Al2O3–ZrO2陶瓷涂层的组织与力学性能

采用超声辅助激光熔覆技术在钛合金基体上制备了Al2O3-ZrO2陶瓷涂层。通过实验研究了超声对涂层组织和力学性能的影响。本文提出了一种超声辅助激光熔覆的新方法。该方法将超声波直接作用于熔池的微区。实验结果表明，超声辅助下涂层的晶粒尺寸和力学性能得到改善。在激光熔覆过程中应用超声振动可以减少涂层的裂纹数量。
