“…In general, according to the microstructure and mechanical properties, welded joints usually include weld metal, base metal, fusion line, and heat-affected zone [24,25]. As shown in Figure 1(a)., the weld metal has stable microstructure and mechanical properties due to the full protection of the metal pool during the welding process.…”

The unevenly distributed mechanical properties of welded joints are one of the important factors, which affect welded joints’ safety seriously. The user-defined field (USDFLD) subroutine in ABAQUS finite element software can introduce variable-dependent material properties. This method can define inhomogeneous materials whose mechanical parameters depend on spatial coordinates and can be used to characterize the uneven mechanical properties of heat-affected zone and fusion zone. By establishing the static crack finite element model of welded joint with continuous change in yield strength, the sudden change in mechanical field in the numerical simulation process of sandwich structure model is eliminated. Compared with the existing numerical simulation methods of local mechanical heterogeneity of welded joints, this method provides a method to realize the structural integrity evaluation of welded joints.

Earning trust among high strength material industrialists for its sophistication, thin protective coating has gained its own maturity to date. As a result of active development in the industries, working tool has the capability of fabricating high strength materials with remarkable durability. For example, unwanted tool wear due to thermally softening problems can be avoided. Therefore, the solution for that is protecting the tool with a thin protective coating that can be coated by various coating deposition methods. With the thin protective coating itself possessing remarkable degree of chemical and mechanical properties, the combination of both makes the thin protective coating lead to a useful extend. This paper provides a review of various research activities and various developments in the wear prone industries. Researchers have explored a number of thin protective coatings for the last century to provide a valuable guide for a most practical option. With the state of the art development of the coating methods such as electrodepositing, radio frequency ion source implantation, electron beam implantation, plasma-sprayed coating deposition, flame-sprayed coating deposition, chemical catalytic reduction deposition, vacuum-diffused deposition, vapor deposition, chemical vapor deposition, physical vapor deposition, plasma arc deposition, and some others, this paper presents the continuous development on the enhancement of the capability of the working tool chronologically since the last century. Such development was studied in connection with the ability to outlast the performance of working tool, which elevates expectations that thin protective coatings are no longer extended far beyond.

“…Current metallurgical-bonding-based surface treatment processes for metals include discharge machining [9], electron beam coating [10], laser coating [11], and plasma transferred arc (PTA) welding [12,13]. Among these processes, PTA welding has gained favor for its efficient welding speed and superior weld quality [14].…”

This study applied plasma transferred arc (PTA) welding to fabricate hard cladding layers by using nickel-based superalloy (NCR7) and niobium carbide (NbC) powders as filler material. The resultant composite claddings were coated onto ductile iron and then analyzed to understand the effect of different quantities of NbC on the solidification structures of the cladding layers and on the characteristics of the interface between the cladding layers and the ductile iron. Cutting tests were also conducted to assess the morphology and mechanism of flank wear on PTA NbC/NCR7 composite cladding tools. The results revealed that the cladding specimens’ microstructures comprised a mixture of dendrites and interdendritic eutectics along with a considerable quantity of carbides (MC, M7C3, and M23C6) scattered within the γ-Ni matrix. Incorporating considerable NbC carbide enhanced the claddings’ surface hardness, but it had a limited effect on improving the flank wear on the turning tools. The flank wear on the composite cladding tools intensified as the NbC content was increased. The wear behavior, defined by brittle fractures and stripped NbC particles, led to a decline in turning tool performance. Accordingly, the Ni-based alloy composite cladding with larger NbC particles appears more suitable for sliding or erosion applications under normal stress conditions.
