Paper Abstract

The set of original pyrometers and the special diagnostic CCD-camera were applied for monitoring of Nd:YAG laser cladding (Pulsed-Periodic and Continuous Wave) with coaxial powder injection and on-line measurement of cladded layer temperature. The experiments were carried out in course of elaboration of wear resistant coatings using various powder blends (WC-Co, CuSn, Mo, Stellite grade 12, etc.) applying variation of different process parameters: laser power, cladding velocity, powder feeding rate, etc. Surface temperature distribution to the cladding seam and the overall temperature mapping were registered. The CCD-camera based diagnostic tool was applied for: (1) monitoring of flux of hot particles and its instability; (2) measurement of particle-in-flight size and velocity; (3) monitoring of particle collision with the clad in the interaction zone.
