前言随着我国电力工业的迅速发展,燃气轮机在列车电站上的应用日益广泛。而燃气轮机的关键另件——叶片,在使用过程中,同时承受高温、腐蚀及机械的作用。为了提高叶片的使用寿命,对叶片材料及表面保护的研究,已成为前进道路上一个急待解决的重要课题。 Preface With the rapid development of China’s power industry, the application of gas turbines in train power plants is increasingly widespread. The key components of the gas turbine - leaves, in the course of use, while under high temperature, corrosion and mechanical effects. In order to improve the service life of the blade, the research on the blade material and surface protection has become an urgent issue to be solved on the way forward.
