Laser Cladding of Ni-Based Powders on S355MC High-Strength Steel Substrate

Laser cladding is a technology in the field of surface engineering.Its characteristics, like versatility, high density of the energy, the various possibilities in selection of the laser beam led to metallic coatings with high quality.This quality however is dependent on the laser cladding equipment, materials and process parameters.The research work aims to investigate the geometrical characteristics of the laser cladding coatings and the behavior regarding bonding with the substrate of four different Ni-based powders on the same base material, S355MC.The S355MC is chosen because of its versatility and high usage in industrial fields.The four Ni-based powders are Metco 12C, Metco 14E, Metco 16CNS and Metcoclad 718.The experimental set-up was formed from a Trumpf TruPulse 556 milliseconds pulsed laser and Precitec WC50 as cladding module.
