“…Multi-layer coatings and surface modification can be carried out over complex geometries using the laser-based cladding technique [ 170 , 171 ]. In a study conducted by Kumar et al [ 172 ], a hard coating of cBN was formed on a Ti6Al4V substrate using a laser cladding technique wherein hard phases of AlTi 3 N, TiN, and TiB 2 were observed.…”

Metallic additive manufacturing is expeditiously gaining attention in advanced industries for manufacturing intricate structures for customized applications. However, the inadequate surface quality has inspired the inception of metallic coatings through additive manufacturing methods. This work presents a brief review of the different genres of metallic coatings adapted by industries through additive manufacturing technologies. The methodologies are classified according to the type of allied energies used in the process, such as direct energy deposition, binder jetting, powder bed fusion, hot spray coatings, sheet lamination, etc. Each method is described in detail and supported by relevant literature. The paper also includes the needs, applications, and challenges involved in each process.

“…Cladding is an advantageous technique to coat the whole workpiece with certain materials that have excellent characteristics. A thin surface layer of desirable material is melted with a parent material using laser irradiation that generates a functional coating having an excellent metallurgical bond with the parent material [55][56][57][58]. A thin surface layer is formed due to the melting of preplaced or fed powder through a laser beam that exhibits a strong bong with the base material.…”

Electrical discharge coating (EDC) process is used to deposit material on workpiece surface from sacrificial or green compact tool electrode in an electrical discharge machine. The paper presents the mechanism of EDC using green compact electrode and powder mixed dielectric methods. The tool electrode material, electrode size, process parameters, and type of dielectrics can directly affect the surface integrity of workpiece. Here, a process map of EDC as a function of process parameters, its classification, advantages, and applications for a wide range of engineering materials offers a proper template for the evaluation of coating phenomena. This study shows that EDC is an economic process as compared to other costlier techniques. Additionally, the effect of various EDM and EDC parameters on surface integrity and tribological behavior of deposited coatings is studied with their pros and cons. Finally, the current research trends of EDC and its challenges are elaborated.

“…Similar to this work, a few previous investigations have focused on the effect of solid lubricant encapsulation on nickel alloy coatings. [41][42][43][44] The aim of this work was to study the effect of substrate dilution and lubricants such as MoS 2 and BaF 2 on hightemperature wear behaviour. The microstructure and mechanical properties were investigated with the change in TIG current.…”

In this study, the impact of substrate dilution on the microstructure and tribological properties of tungsten inert gas (TIG)-deposited self-lubricating claddings was investigated. The dilution of Ti content on cladding increased as the TIG current increased, and the microhardness of the cladding decreased. The content of intermetallic phases such as TiNi and TiC increased with the increase in TIG current. The tribological studies revealed that coating dilution at higher TIG currents has prominent effects on wear behaviour at elevated temperatures. In both clads, the percentage decrease in hardness from higher TIG current to lower TIG current was noted as 31%. The higher dilution of Ti content in the cladding was found to be beneficial in tribological studies performed, especially at higher temperatures (≥400). Also, solid lubricants such as MoS2 and BaF2 encapsulation in the nickel alloy were found to be beneficial at both low and high temperatures.
