Formation of Multilayer Claddings using High-power Fiber Laser Radiation

Fabricated and investigated samples of multilayer cladding on the flat surface are obtained using a laser cladding technology. Iron-based powder was used in the study. Geometric parameters of track depending on the process parameters were determined. The effect of thermal fields on the quality of the coating was analyzed. Optimal strategy areas adjacent to tracks and each subsequent layer deposition have been identified. Microhardness of the resulting coatings was measured. Result of this work is a multi-layer coating in order to restore and improve the surfaces of parts, which exposed to wear.
