The collaboration of precipitated particles and austenitic matrix plays a significant role in the overall wear performance of high‐manganese (high‐Mn) austenitic steels. The austenitic matrix cannot support micrometer‐sized precipitates because of its poor Young's modulus and hardness before work hardening, and the relative sliding of abrasive particles over the matrix may result in the precipitates detaching from the matrix and deteriorating the overall wear performance of the steels. Herein, a solid‐solution temperature of 1100 °C is applied to balance the size of the austenite grains and precipitates. Different volume fractions of submicrometer V2C are precipitated in the austenitic matrix by aging at different temperatures, and the volume fraction of submicrometer V2C precipitates increases with aging treatment temperature. When the aging temperatures are higher than 450 °C, Young's modulus and nanohardness of the austenitic matrix are significantly enhanced, and the overall Brinell hardness and strength of the specimens are also improved. The improvement in the mechanical properties of the matrix is mostly related to the precipitation strengthening of nanoscale precipitates, and the enhancement in the overall hardness of the steels is mainly related to a sufficient amount of precipitated submicrometer V2C particles in the austenitic matrix.

“…79 In the case of multilayer deposition, the overlapping bead width zone experienced high-temperature re-heating from a successive bead deposition, which resulted in its structural evolution compared to that of the previously deposited metal. 80 Wear resistance was higher for the two layers compared to single-layer deposition and the chemical composition varied with the degree of dilution. 42 Laser cladding-assisted hardfacing technology may be the substitute of PTAHF to improve wear and thermal fatigue resistances and can deposit material by smooth transaction from the substrate to the hardfacing layers.…”

Critical equipments of process and heavy engineering industries are prone to significant wear due to intense service conditions. Uneven and uncontrolled wear causes significant changes in dimensional and geometrical accuracies of the part surfaces, which adversely affect the parts’ functionality and service life of these parts. Shorter service life of these equipments and subsequent replacement of the same is one of the serious economic concerns. Hardfacing or hardsurfacing is comparatively an advanced metal deposition technology to deposit a hard and complex metal substrate layer on simple and softer base material surface. This process is gaining popularity at commercial level due to its unique capabilities to develop superior wear, corrosion, and impact resistance properties on worn out parts and offer huge economic advantage as substitute to costly replacement. The primarily aim of this study is to present a comprehensive review of the work done on the probable candidates for deposition materials, and summarize the influence of various process parameters on hard-faced surface characteristics. The critical issues like dilution, debonding, and residual stresses have been discussed for multi-layered hardfacing for iron-, nickel-, and cobalt-based hardfacing materials. The secondary aim of this study is to address practical issues such as selection of proper combination of base-substrate material, to understand the response characteristics of ‘plasma transferred arc hardfacing (PTAHF)’ process to minimize the de-bonding, dilution, and residual stresses and finally to improve quality of hardfacing practice.

“…Coating on the pin of an SKD61 stirring rod for FSW causes a better wear resistance. The plasma transferred arc (PTA) process is a surface coating treatment [9,10]. The plasma arc between the electrode and the substrate is used to coat the alloy powders on the substrate to form a highly wear resistant coating layer.…”

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.
