摘要：

The TRUMPF 505 DMD machine with a 5-kW CO2 laser was used to enable scaling-up laser cladding (LC) to an industrial level. The aim of this study is to enhance product quality and to assure process stability and reproducibility by means of optical monitoring. Two originally developed pyrometers and an infrared camera FLIR Phoenix RDAS (TM) are employed in the LC of Ti6Al4V powder. The variations of brightness temperature versus laser power and cladding velocity are analyzed. A CCD camera-based diagnostic tool is applied for online monitoring of particle-in-flight velocity in coaxial powder injection.
