“…According to Gabriel T. et al [6], laser cladding makes micron level coating on the substrates and by modifying the laser power the cladding efficiency can be varied. The cladding process with high speed laser improves the cladding efficiency than the low speed laser [7]. The laser cladding accuracy is appreciated.…”

In this work, Cladding was done on SS316L alloy through the CMT process using Stellite-6 filler wire. 31 experiments were done at different welding conditions as per CCD matrix. The cladding specimens were characterized by macro and micro-study, Vickers microhardness evaluation and corrosion resistance analysis. An optical microscope, SEM-EDAX, and XRD were used to predict the structural characterizations, presence and the distributions of the elements. Based on the study higher voltage & welding speed showed appreciable hardness at the interface & cladding regions. The thickness of the interface was noted at a maximum of 190 μm. The EDS spectra showed that Fe, Cr and Co were the major elements in the clad and interface regions. The Co-rich phase and the low content of element O are found in the low corroded regions on the specimen. The maximum hardness observed at cladding and interface were 378 Hv and 270 Hv respectively.

“…Thus, the laser cladding technique has been developed and used to enhance the surface performance of the Cu and its alloys, [ 10–12 ] especially in strengthening the surface of the Cu for continuous casting mold. [ 9,13–16 ] However, the shear strength, which illustrates the quality of the metallurgical bonding between the coating and the Cu substrate, received little attention.…”

Laser Cladding Fe/FeCr Coatings on Continuous Casting Cu Mold

The crystallizer is the key component controlling the solidification process and is mainly made of pure Cu. The poor wear resistance and oxidation resistance of pure Cu limit the working life of the Cu crystallizer. Herein, Fe/FeCr coatings are designed and successfully fabricated on the Cu substrate by laser cladding technique. The composition, microstructure, mechanical, and thermal properties of the Cu–Fe/FeCr composite are investigated. The coating is composed of a body‐centered cubic Fe–Cr alloy phase. The grains on the surface are equiaxed grains with an average diameter of 2 μm. The coating exhibits a tensile strength 3 times of Cu substrate and well elongation thanks to the fine‐grain structure. The interface between coating and substrate is metallic bonding and possesses a shear strength of as high as 200 MPa. The coating shows obvious advantages in wear resistance and antioxidation at high temperatures in comparison to Cu substrate. The laser cladding Cu–Fe/FeCr composite is promising to prolong crystallizer life for continuous casting.

“…To overcome this problem, one commonly used method is a preheating substrate [17,18]. Among various heating methods, induction heating has the advantages of high-speed and local heating, which has potential application value in the preheating of copper surfaces [19]. How to achieve the dynamic matching control of plasma cladding and substrate preheating is the key and difficult point to obtain high-quality coating.…”

Plasma cladding coupled induction heating was developed and successfully used to fabricate Ni60A coating on the surface of copper pipe. By matching the swing arc with the rotating copper pipe, the cladding efficiency was as high as 32.72 mm2/s. From the head to the tail of the coating, the wear resistance changed from 4.5 to 1.8 times that of pure copper. During the cladding process with constant current, the surface temperature of the cladding zone and the bath depth gradually increased. The corresponding dilution ratio increased, accompanied by the widening of the interface transition zone and the growth of precipitated phases (CrB and Cr23C6). Due to the gradient change of composition, the coating can be regarded as an in situ synthesized gradient coating. The critical point of sudden change of temperature in cladding zone was 850 °C, at which point the wear mechanism changed from abrasive wear to adhesive wear. The proper surface temperature of cladding zone should be controlled within 600–850 °C, which can be achieved by matching the cladding current and induction heating power. Results indicated that plasma cladding coupled induction heating is a potentially effective method to prepare high-quality coating on the surface of a large-complex-curved copper component.
