“…Liu et al [9] prepared Ni-based/WC p coating by the method of combining PTA and PMI, which effectively prevented the sinking of WC. Gowtham et al [10] promoted the uniform distribution of WC particles in the Ni-based/WC composite coating by adjusting the laser cladding parameters. Wang et al [11] explained several heat damage mechanisms of WC particles in the laser induction hybrid cladding process.…”

With the aim of improving the surface properties of copper, WC/Ni60A composite coatings were successfully prepared by plasma cladding. A good metallurgical bonding was formed between composite coating and copper substrate. The large amount of dispersed WC and W2C phases in the coating significantly increased the microhardness (17 times that of the copper substrate). With the rise in temperature, the wear resistance of the coating first increased and then decreased. At 400°C, the coating had the best wear resistance due to the lubricating effect of the oxide layer. However, due to the simultaneous occurrence of various wear mechanisms, the wear resistance at 600°C was significantly reduced, so the service temperature must be controlled below 600°C.

“…The effect of lower Cr content and a higher Si/B ratio was to reduce the quantity of borides and modify the nature of the eutectic phases. Some authors have reported the results of laser cladding deposits with Ni-Cr-B-Si alloys reinforced with Tantalum [12] and with WC [13][14][15]. Ta significantly improves the hightemperature wear resistance of Ni-Cr-B-Si coatings; TaC carbides in Ta-reinforced coatings are only formed in the shape of a block.…”

Nickel-based Ni-Cr-Si-B self-fluxing alloys are excellent candidates to replace cobalt-based alloys in aeronautical components. In this work, metal additive manufacturing by directed energy deposition using a laser beam (DED-LB, also known as LMD) and gas-atomized powders as a material feedstock is presented as a potential manufacturing route for the complex processing of these alloys. This research deals with the advanced material characterization of these alloys obtained by LMD and the study and understanding of their solidification paths and strengthening mechanisms. The as-built microstructure, the Vickers hardness at room temperature and at high temperatures, the nanoindentation hardness and elastic modulus of the main phases and precipitates, and the strengthening mechanisms were studied in bulk cylinders manufactured under different chemical composition grades and DED-LB/p process parameter sets (slow, normal, and fast deposition speeds), with the aim of determining the influence of the chemical composition in commercial Ni-Cr-Si-Fe-B alloys. The hardening of Ni-Cr-Si-Fe-B alloys obtained by LMD is a combination of the solid solution hardening of gamma nickel dendrites and eutectics and the contribution of the precipitation hardening of small chromium-rich carbides and hard borides evenly distributed in the as-built microstructure.

“…Tungsten Carbide/Ni particles significantly increased the microhardness and wear resistance of Ni-based alloy coatings [22,23]. Adding B 4 C particles to traditional nickel-based alloy coatings can improve their performance [24]. Incorporating Tungsten Carbide/Ni particles into Ni-based alloy coatings significantly improved their microhardness and wear resistance.…”

Metal-based ceramic composite laser cladding offers substantial compensations in enhancing brake disc surface characteristics. Laser cladding was utilized to combine B4C powder (10–40%) with Ni 63 powder to make Boron Carbide (B4C)/Nickel 63 composite coatings. For the subsequent experiments, the specimens were ground and polished. Bonding strength, fracture toughness, and residual stress were examined with the B4C content. The fracture morphologies were checked using a scanning electron microscope (SEM). It was observed that the bonding strength of various coatings might approach 175 MPa. Best bonding was observed when the B4C level was between 15% and 30%. The porousness of the coating continuously raised as B4C content increased. The coating’s maximum permeability was 5.6% after the B4C level reached 30%. As the B4C level in the coating grew, the coating’s compression resistance decreased. The bonding strength was within desirable limits, and compression resistance was consistently strong. The material bending strength increased when the B4C materials were reduced below 35%; at this level, the bending strength was highest. The bending strength was covered by the optimal range of bonding strength. Good bonding strength and mechanical characteristics were achieved when B4C content was 20% to 30%. The 20% B4C coating had the smoothest fracture morphologies and the strongest bonding strength, making it the most stable. For the estimation of total matrix deformation and corresponding coating stress on coated brake discs, Ansys software was utilized to create a static structural model.
