“…Fesharaki et al [14] reported better metallurgical bonding of Inconel 625 coating prepared by laser cladding than that developed by Tungsten Inert Gas Welding (TIG) cladding. Tanigawa et al [15] found that the HAZ of laser cladding prepared Ni-Cr-Si-B alloy coating on C45 carbon steel can be shrunken by employing smaller particles.…”

“…Nickel-based superalloys are widely used in the laser cladding process due to their superior mechanical properties and wear resistance [16][17][18]. Chen et al [3] found that the microhardness of the Ni-Cr-B-Si composite coatings increased with increasing laser scanning speed (5,10,15, and 20 mm/s). Sun et al [19] studied the effects of NbC on the wear properties of Ni45 coating and reported that the microhardness and wear resistance were significantly improved by the addition of NbC.…”

The effects of laser scanning speed on the microstructure, microhardness, and corrosion behavior of Ni45 coatings were investigated by using optical microscopy (OM), scanning electron microscopy (SEM), X-ray diffraction (XRD), microhardness, and electrochemical measurements. The results showed that increasing laser scanning speed promotes the transformation from planar crystals to dendrites and refines the grains concurrently. The γ-(Ni, Fe), FeNi3, and M23(C,B)6 are identified as the primary phase composition in the Ni45 coatings regardless of the laser scanning speed. Thereinto, the formation and growth of M23(C,B)6 precipitates can be inhibited with increasing laser scanning speed due to the higher cooling rate, which affects the microhardness distribution and corrosion resistance of the coating. On the one hand, the microhardness of the whole coating presents a downtrend with increasing laser scanning speed due to the reduction of M23(C,B)6 phase. On the other hand, the corrosion resistance in 0.5 M NaCl solution is improved to some extent at higher laser scanning speed because the less precipitation of M23(C,B)6 reduces the depletion of Cr around the precipitates. In contrast, all the coatings exhibit undifferentiated but poor corrosion resistance in the highly corrosive 0.5 M NaCl + 0.5 M H2SO4 solution.

“…This reduction is also linked to the shorter nozzle residence time on the deposition region, which influenced the amount of material that was deposited. Tanigawa et al [42] also found that the wettability of beads improved when the particle size was reduced. The powder flow rate is another variable that directly influences the geometric characteristics of the deposition.…”

In the laser cladding process, control of the process parameters and knowledge of the characteristics of the materials used are essential for obtaining depositions with excellent metallurgical union, satisfactory dilution values, absence of defects, and acceptable geometric characteristics. Without such precautions, depositions can exhibit low or excess dilution, low wettability, and the presence of pores, consequently reducing the performance of the materials. The aim of the present work was to evaluate the effects of the laser beam power, with maximum power of 4000 W and continuous wave mode, and scanning speed in laser cladding processes employing the AISI 316L austenitic stainless steel and the AISI 431 martensitic stainless steel, considering the geometric characteristics, dilution, and structural defects of the depositions. It was found that the laser power had a greater effect on the width and dilution of the depositions, while the scanning speed influenced the deposition height. The depositions of AISI 431 steel presented dilution values between 9 and 25%, using power settings between 1400 and 1600 W. The depositions of AISI 316L steel required higher power values between 1900 and 2600 W to achieve dilution values between 15 and 41%. The existence of pores and satisfactory hardness values were observed for both materials, with the average of microhardness of 522 HV0.5/15 and 356 HV0.5/15 on the AISI 431 and AISI 316L depositions. It was also found that the different characteristics of the addition metals, considering their morphology, particle size distribution, and flow rate, led to significant changes in the geometric features of the depositions.

“…Because of the high energy density during the process, coatings are deposited with precise dimensions and a high production efficiency with minor heat-affected zones, low dilution rates, and outstanding metallurgical bonding. Hence, this technology has been widely used in remanufacturing and restoration of important high-value parts [3][4][5][6].…”

Laser cladding on curved surfaces is essential in industrial applications for restoration and remanufacturing of high-value parts. This study investigated the influence of different factors on clad width, clad height, and dilution rate in curved surface laser cladding with curved path. Mathematical models were developed using central composite designs to predict these geometric characteristics by controlling laser power, scanning speed, gas flow, and altering the outside radius of the cylindrical substrate. Analysis of variance and response surface methodology indicated that clad width increased with increasing laser power and reducing scanning speed. Clad height positively correlated to laser power and negatively correlated to the outside radius of the cylindrical substrate. Increasing the laser power while decreasing the scanning speed led to an increase in dilution rate. Afterwards, the geometric characteristics of the clad were improved by optimizing these factors with the target to maximize clad width and height as well as to minimize dilution rate. The difference between model predictions and experimental validations for clad width, clad height, and dilution rate were 3.485%, 3.863%, and 6.566%, respectively. The predicted accuracy was verified with these models, and they were able to provide theoretical guidance to predict and control the geometric characteristics of curved surface laser cladding with a curved path.
