To enhance the sliding wear and corrosion behavior of steels with low carbon content, cermet composite coatings are usually deposited on their surface by various deposition processes. Laser cladding, compared to other deposition techniques such as electroplating, arc welding, and thermal spraying, has numerous advantages to produce such protective coatings. The paper presents the optimization of laser cladding deposition speed versus energy density in order to obtain WC-Co/NiCrBSi coatings with Ni-Al addition free of defects and reduced porosity deposited on low carbon steel substrate. The microstructure and chemical composition were investigated by SEM combined with EDX analysis while XRD was performed in order to examinate the phases within the coatings. In order to investigate the cladding speed influence on the coatings, hardness measurements, POD (pin on disk) wear tests and corrosion tests in 3.5% NaCl solution were carried out. The results showed that an optimal cladding speed has a crucial impact on the microstructure, composition, and hardness. It was found out that optimizing the cladding deposition speed proved to be effective in enhancing the sliding wear resistance and corrosion behavior by controlling the iron content within the coatings.

Laser cladding as an emerging surface modification technology can be widely adopted for surface modification. In this study, 27SiMn was selected as the substrate, the powder was a self-made iron-based alloy, and the thermophysical properties of the material were predicted by the CALPHAD algorithm. The numerical model of the laser cladding process is established by setting reasonable hypothetical condition, initial condition, boundary condition, and solver parameters. In order to verify the accuracy of the numerical model, 10 sets of experiments have been carried out, and the agreement between the model calculation results and the experimental results reached 92%. Through the study of energy distribution in the laser cladding process, it is found that about 10% of the laser energy is used to heat the substrate to form a melt-pool, and at least 53% of the energy is radiated into the environment. Finally, the effects of temperature gradient and solidification rate on the microstructure of the cladding layer were explored.

“…Interesting applications for LMD are to improve the wear or corrosion resistance of surface parts [ 17 ] and their use to repair damaged surfaces [ 18 , 19 ]. Tool and die lifetimes can be extended, adding over their surface new layers or repairing their surface with the LMD process [ 20 ].…”

The effect of process parameters and the orientation of the cladding layer on the mechanical properties of 316L stainless steel components manufactured by laser metal deposition (LMD) was investigated. High aspect-ratio walls were manufactured with layers of a 4.5 mm wide single-cladding track to study the microstructure and mechanical properties along the length and the height of the wall. Samples for the tensile test (according to ASTM E-8M-04) were machined from the wall along both the direction of the layers and the direction perpendicular to them. Cross-sections of the LMD samples were analyzed by optical and scanning electron microscopy (SEM). The orientation of the growing grain was observed. It was associated with the thermal gradient through the building part. A homogeneous microstructure between consecutive layers and some degree of microporosity was observed by SEM. Uniaxial tension tests were performed on samples extracted from the wall in perpendicular and parallel directions. Results for ultimate tensile strength were similar in both cases and with the wrought material. The σ0.2 were similar in both cases but slightly superior to the wrought material.
