“…The defects, mainly the cracks, propagated along the boundaries and heavily downgraded the wear performance [ 33 ]. However, the impact of inhomogeneity in the material properties can be reduced by implementing a gradient cladding layer (addition of one more layer) over the substrate [ 72 ]. Moreover, this additional layer can remove the porosity and other defects to too much extent and remove the sudden dip in hardness towards the coating-substrate interface.…”

Ceramic coating has applications in enhancing the material’s properties and can significantly improve the material’s usability in varied temperatures and adverse operating conditions and widen its applicability scope. It can add to the various properties such as wear resistance, high-temperature degradation, thermal conductivity, material toughness, tensile strength, corrosion resistance, friction reduction, electric insulation, and the lifespan of the material. Various techniques have been suggested and implemented to achieve ceramic coating on a metal surface, each having their respective advantages and disadvantages. Hence, they can be distinguished for their applicability in different places. The bonding mechanism of metal particle systems has been researched to date, but there are still certain uncertainties regarding the ceramic particle system because of the dissimilarities in properties. The paper aims to profoundly investigate the various coating technologies available through welding processes and do a comparative study through numerical analysis and experimental results on the properties of coatings obtained from two broad categories of welding—solid-state and traditional/fusion processes. It was found that the solid-state processes in which the temperature remained well below the fusion temperatures overcame the mismatch in property and produced reliable coatings with enhanced mechanical properties.

“…Plasma cladding involves the use of high-power density beam to a coat layer or layers of the surface parts for the improvement of the surface properties [11]. Given the compact coating, high binding strength, wide availability of materials, high efficiency and low cost of plasma cladding, it has been developed rapidly in surface engineering [12][13][14][15] and widely used in strengthening and repairing parts.…”

To improve the cutting performance, the red hardness and wear resistance of M2 high-speed steel, as well as expand the application field, in this work, a coating was fabricated via plasma cladding on M2 high-speed steel using Ni, Cr and Cu alloy elements as precursor materials. The distribution and composition of alloying elements, microhardness and wear resistance of the coating were studied. The results show that the NiCrCu cladding layer contains many types of carbides. The secondary hardening caused by the dispersion of carbides can significantly improve the hardness, red hardness and wear resistance of material. The hardness of cladding layer is above 950 HV, after holding at 600 °C for 4 h, the hardness is above 932 HV. The alloy elements are evenly distributed, but, due to the rapid solidification after the cladding, there are composition fluctuations in the longitudinal direction. The wear resistance of the cladding layer is excellent; the wear rate is reduced from 1.75 to 1.44 × 10−6 mm3 N−1 m−1 or less; and the wear mechanism is a combination of abrasive wear and adhesive wear.

“…25,26 The surface hardness of the workpiece is obviously improved after the plasma cladding, which provides a guarantee for the excellent wear resistance of the cladding layer. 23,27 With the development of plasma cladding technology, it began to be used to restore the size of crapped parts in remanufacturing. [28][29][30] Based on an analysis of the wear amount on the working surface of a scrapped crankshaft made from nodular cast iron, to achieve successful remanufacturing of the scrapped crankshaft, four possible cladding powders and various technological parameters were used for testing in this work.…”

Remanufacturing technology has a wide range of applications in the repair of scrapped parts with a certain remaining service life. In this work, a scrapped crankshaft fabricated from nodular cast iron that had failed from working surface wear was remanufactured via a plasma cladding process. Taking into account the wear amount on the working surface and the characteristics of nodular cast iron, in this article, cladding layer parameters were designed and two types cladding powders, Fe-based and Ni-based, were prepared, respectively, to perform the cladding experiment. After examining different process parameters, relatively smooth cladding layers were obtained using four powders. The cladding experiment results showed that the powder No. 3 exhibited superior qualities when combined with proper processing parameters. When applying powder No. 3 to the main journal of crankshaft, a higher quality of cladding layer was achieved.
