本文介绍了钴基堆焊合金在航空发动机镍基燃气涡轮机叶片上的应用。现有技术，手工氩弧焊，是耗时的，严重依赖于操作者的技能，并遭受缺乏再现性，特别是在镍稀释水平产生。使用激光和吹制粉末技术引入硬质堆焊合金，能够生产具有最佳磨损特性、无热影响区开裂且质量稳定的熔覆层。该过程能够在微处理器控制下自动化和运行。
This paper describes the application of a cobalt-based hardsurfacing alloy to a nickel-based gas turbine blade for aero-engine use. The prior technique, manual argon arc welding, was time consuming, critically dependent upon operator skill and suffered from a lack of reproducibility, particularly in the level of nickel dilution produced. The use of a laser and a blown-powder technique to introduce the hardsurfacing alloy enables clad deposits of optimum wear characteristics, free from heat-affected zone cracking and of a consistent quality to be produced. The process is able to be automated and run under microprocessor control.
