摘要

激光焊接镍钛诺是一种很有前途的加工方法。研究激光热输入对镍钛诺海水浸焊构件不同表面性能和耐腐蚀性能的影响是必要的。研究了激光热输入对激光焊接试样的各种物理、化学和机械表面性能以及耐腐蚀性能的影响。相分离样品的耐腐蚀性能不如其他激光焊接样品。由于熔池的再循环和钛在顶表面的富集，使得顶表面具有较好的耐腐蚀性能。

Comparative study on weld characterisation and corrosion performance of laser-welded NiTinol

ABSTRACT Laser welding of NiTinol is a promising fabrication method. An understanding of the effects of laser heat input on different surface properties and corrosion resistance behaviour is needed for laser-welded sea water-flooded components of NiTinol. Here the effect of laser heat input on various physical, chemical and mechanical surface properties along with the corrosion resistance behaviour of the laser welded samples was investigated. The corrosion resistance performance of the phase-separated samples was found to be inferior to the other laser-welded samples. The top surface showed a superior corrosion resistance performance because of the recirculation of the melt pool and Ti enrichment on top surface.

期刊介绍： Science and Technology of Welding and Joining is an international peer-reviewed journal covering both the basic science and applied technology of welding and joining. Its comprehensive scope encompasses all welding and joining techniques (brazing, soldering, mechanical joining, etc.) and aspects such as characterisation of heat sources, mathematical modelling of transport phenomena, weld pool solidification, phase transformations in weldments, microstructure-property relationships, welding processes, weld sensing, control and automation, neural network applications, and joining of advanced materials, including plastics and composites.
