Spraying method for plasma physical vapor deposition coating of concatemer turbine guide blade

The invention relates to a spraying method of a plasma physical vapor deposition coating of a multi-conjoined turbine guide vane, the spraying method is carried out by using a manipulator and a double-shaft positioner, and a turntable of the double-shaft positioner can rotate around a central shaft and can tilt below 45 degrees. According to the preparation method provided by the invention, plasma physical vapor deposition is adopted, a complex molded surface and a shielding factor of the multi-conjoined turbine guide blade are combined, and track optimization of a manipulator and a double-shaft positioner is matched, so that the uniformity of coating deposition can be effectively improved; the problem of uniformity of the inner side of the margin plate, the included angle position of the margin plate and the blade body and the spraying deposition thickness of the blade body is solved. 本发明涉及一种多联体涡轮导向叶片等离子物理气相沉积涂层的喷涂方法，所述喷涂方法利用机械手以及双轴变位机进行，所述双轴变位机的转盘能够绕中心轴自转，且能够进行45°以下的倾转。本发明提供的制备方法采用等离子物理气相沉积，结合多联体涡轮导向叶片复杂型面和
