“…From the literature [12,13], the different overlaying currents will affect the degree of dilution effect between the substrate and the overlayer. In this study, the interface region is set to zero; the overlayer is in a forward direction, and the semiquantitative composition and microhardness of the subsurface of the coated specimens were analyzed.…”

The friction stir welding process (friction stir welding/processing, FSW/FSP) has wear problems related to stirring tools. In this study, the plasma transfer arc (PTA) method was used with stellite 1 powders (Co-based) to coat on the head of a SKD61 stirring tool (SKD61-ST1) in order to investigate the wear performance and phase transformation of SKD61-ST1 after FSW. Under the same experimental parameters, the wear data were compared with the high-speed steel SKH51 (tempering material SKH51-T and annealed material SKH51-A) and tungsten-carbide cobalt (TCC). Results showed the PTA coating was a γ-Co solidification matrix with M7C3 and M23C6 carbides. After FSW, the wear resistance of SKD61-ST1 was better than that of SKH51-A and SKH51-T and lower than that of TCC. The SKD61-ST1, SKH51-A, and SKH51-T stirring tools exhibited sliding wear after FSP, where the pin and shoulder of the stirring tool formed a phase transfer layer on the surface, and the peeling of the phase transfer layer caused wear weight loss. The main phase of the phase transfer layer of the SKD61-ST1 tool was Al9Co2. The affinity and adhesion energy of the Co-Al phase was lower than that of Fe-Al phase, and the phase transfer layer of the SKD61-ST1 tool was thinner and had lower coverage, thereby increasing the wear resistance of the SKD61-ST1 stirring tools during FSW.

“…Lin and Lui 70 used EDA process to modify the surface of ferritic spheroidal graphite (SG) cast iron. Under the conditions of fixed EDA parameters and variable chemical composition of the electrodes (Fe: 75 mass %, Si, Al, Ni, Mg and Cr), the elements of the tool were deposited on the substrate surface.…”

Electrical discharge machining has emerged as one of the most accepted non-traditional machining methods that have the capability of attaining complex shapes and better feature size in difficult-to-machine materials. In this article, an advanced review of conventional electrical discharge machining and micro–electrical discharge machining of difficult-to-machine materials, such as nickel and its alloys, titanium alloys, stainless steel (SUS 304) and advanced ceramics, has been presented. The review begins with an introduction to the conventional electrical discharge machining and micro–electrical discharge machining processes, followed by classifications and a brief discussion on different aspects of micro-manufacturing methods. The current research trends and developments, research gaps and challenges of the conventional electrical discharge machining and micro–electrical discharge machining of nickel and its alloys, titanium alloys (Ti6Al4V), stainless steel and advanced ceramics are also discussed in depth. A brief note on future research trends, based on the available literature, has been included in the last section.
