“…Moreover, using the CAD design and robotics technology is possible to create new complex surfaces or precise recondition of worn components by using coaxial laser cladding technology. There is a wide range of powders and limitless possibility of alloys mixture by frequently using Ni, Co, or Fe [ 4 , 5 , 6 ] as base matrix with the addition of elements (Si, Ti, Cr, B, V) [ 4 , 7 , 8 , 9 ], carbides (TiC, WC, VC) [ 10 , 11 ] or ceramics (Al 2 O 3 , TiO 2 ) [ 12 , 13 ]. All the above presented powders formerly designed for thermal spraying (e.g., high velocity oxygen spraying, flame spraying, plasma deposition) are studied nowadays and used for advanced laser cladding process.…”

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.

“…Powder metallurgy has become one of the important methods to prepare particle reinforced composites with low cost, high efficiency, and wide applicability [7, 8]. As the hardest metal carbide, TiC is a very stable compound with a high melting point, high hardness, high Young's modulus, high chemical stability, wear resistance and corrosion resistance, and has become one of the best materials for particle reinforcement [9, 10].…”

TiC nanosheets with a thickness of about 50 nm were successfully prepared via solvent thermal etching Ti 3 AlC 2 in hydrofluoric acid solution at 120°C. TiC reinforced copper-matrix composites with a content of 3, 5, 7, 9, 10, and 12 wt% were prepared by powder metallurgy with copper powder and TiC nanosheet as raw materials. The friction and wear behaviours of copper matrix composites were tested on a ball on disc under dry sliding conditions. The results showed that TiC particles were evenly distributed on the substrate and had a good combination with the substrate. The friction coefficient and wear scar widths of the composites gradually decreased with the increase of TiC nanosheet content, the maximum reduction of friction and wear was achieved under the content of 7 wt% for the TiC nanosheets. The increase in load causes the increase of friction coefficient and wear scar widths. The wear of pure copper is mainly adhesive wear and peel wear. The addition of TiC nanosheets improves the bearing capacity of copper matrix composites, and the wear mechanism is mainly abrasive wear.

In this study, the coatings were fabricated on the 3Cr13 stainless steel substrate by laser cladding. The microstructure, phase compositions and the detailed information about the crack propagation of the coatings were investigated systematically. A comparative study on the corrosion resistance of the traditional of 3Cr13 stainless steel and laser cladding blades was conducted. The standard Gibbs free energy variation of carbides, phase composition and precipitation sequence were precisely calculated. The results showed that the microstructure near the fusion zone was mainly composed of cellular crystals and dendrites. Meanwhile, its microstructure had changed in the upper middle of the coatings. The calculated results showed that the phases formed at the equilibrium state consisted of α-Ferrite, σ and M23C6 carbide. In the vicinity of fusion line and the middle of the coatings, the crack distributed along α-Ferrite grain boundaries. On the top of coatings, the crack traversed the matrix and carbide.
