“…The EBW was proved to be a better technique for welding aluminium metal matrix composite as it forms a smaller number of precipitates. Lima et al 15 conducted a comparative analysis of wear and corrosion behaviour of Stellite 6 coating deposited by gas tungsten arc welding (GTAW) hot wire cladding process and high-velocity oxy-fuel (HVOF) spraying technique. The microhardness and abrasive wear resistance were higher in coating deposited by the HVOF technique, but the erosive wear resistance and corrosion resistance were more increased in the layer deposited by GTAW hot wire cladding process.…”

The present work reviews the laser cladding process as a repairing technique and the conventional repairing techniques and different heat source models. In this review work, the authors have tried to address the various traditional methods studied for repairing and surface modification. The dominantly used heat source model for numerical modelling of the repairing techniques and the mechanism of the laser cladding process, along with its advantages over the conventional repairing techniques, is also reviewed. This paper also focuses on the predominantly used laser of high power for the cladding process and the effect of process parameters on the quality of the clad layer. The different materials used as clad materials for repairing purposes during the laser cladding process have also been discussed briefly. In this paper, the authors have surveyed literature from different regions of the globe and considered the literature since 1969. This review discusses the various conventional repairing techniques used for repairing, heat source model, process parameters, and different materials used in the laser cladding process. The authors have also briefed the advantages, disadvantages, and application in each of the sections. The use of laser cladding for in-situ repairing process, development of a precise model, use of low-power laser, and application of laser cladding for actual engineering components was also considered in future research work.

“…The 42CrMo alloy steel has been widely used in drilling industry. With the increasing depth of drilling, the salt water of drilling fluid will be continuously injected and tools of downhole drilling will be seriously corroded [1][2]. In general, the cost of replacing parts is quite high, and on the contrary, using remanufacturing repair technology to improve the performance of workpieces is an effective means.…”

To delay the corrosion rate of 42CrMo steel in oil and gas drilling industry, Co-based coatings were prepared on 42CrMo steel through laser cladding at different overlap rate (20%, 50% and 60%). The relationships between microstructure and corrosion behaviour of Stellite-6 coating in Cl ion corrosion medium were analysed by means of SEM, polarization curve and EIS. The results showed that the microstructures of Stellite-6 coating were mainly equiaxial crystal, and the corrosion form of cladding Stellite-6 alloy was pitting corrosion. The best corrosion resistance of Stellite-6 coating was the coating prepared at the overlap rate 50%. The formation of passivation films (Cr2O3 and Cr(OH)3) on the coating could obviously improve the corrosion resistance in Cl ion corrosion medium.

“…Singh et al [5]revealed that the wear resistance and hardness of cladding were mainly influenced by current applied followed by welding travel speed, standoff distance, and flow rate of shielding inert gases. Lima et al [6]showed enhancement in the wear and corrosive properties of the coating. Kumar et al [7] studied experimentally and revealed better adhesion between Fe-SiC and SS304 substrate with improvement in anti-abrasive properties with higher microhardness.…”

A great deal of investigation on gas tungsten arc cladding (GTAC) is focused on the study of enhancements in the microstructure, mechanical and tribological features of the cladding. The selection of right process parameters is a critical issue for the researchers. Decision makers in the industries must analyze a wide variety of parameters based on a set of contradictory criteria. Several multi-criteria decision-making (MCDM) techniques are now available to add values in selection of these parameters. The application of the TOPSIS and MOORA techniques to identify the best configuration of processing parameters in the gas tungsten arc cladding (GTAC) process is investigated in this work. The best processing parameters set for the multiple performance attributes should be welding current: 70 amp, speed: 240, argon flow: 13 and standoff distance 3.5 (TOPSIS-PCA) and welding current: 50, speed: 300, argon flow: 13 and standoff distance 3.5 (MOORA-PCA).A comparison of MOORA-PCA and TOPSIS-PCA demonstrates the superiority of TOPSIS over MOORA technique. The prediction accuracy of the TOPSIS-PCA hybrid approach model is found better than MOORA-PCA technique.
