Abstract

The main objective of this research is to design and analyse laser cladding with different additive materials and variable cladding parameters. Coatings were produced to increase the corrosion and mechanical resistance of highly stressed rotating parts. Metallographic analysis of the coatings was carried out using optical microscopy, surface hardness measurements and hardness profiles. The coatings were also subjected to wear tests. The laser coatings were made of materials ROCKIT-401, AISI M2 and 410L. All coatings were of high quality with no significant defects. ROCKIT-401 is a suitable material for cladding of wear and corrosion resistant parts due to its chemical composition, high hardness and wear resistance.

Keywords: Laser cladding, metallographic analysis, hardness profiles, wear resistance
