“…The investigation provided by Li et al [34] confirmed the improvement in the Vickers hardness magnesium alloys with the addition of scandium compared to pure magnesium alloys. One of the implications of this research is the conclusion that the addition of scandium could enhance the wear resistance of magnesium alloys [34].…”

Based on the results achieved in systematic studies of structure formation and the formation of multicomponent phases, a scandium-containing filler metal from system alloy Mg-Zr-Nd for welding of aircraft casting was developed. The influence of scandium in magnesium filler alloy on its mechanical and special properties, such as long-term strength at elevated temperatures, was studied by the authors. It is established that modification of the magnesium alloy with scandium in an amount between 0.05 and 0.07% allows a fine-grained structure to be obtained, which increases its plasticity up to 70% and heat resistance up to 1.8 times due to the formation of complex intermetallic phases and the microalloying of the solid solution. Welding of the aircraft castings made of magnesium alloy with scandium-containing filler material allows obtaining a weld with a dense homogeneous fusion zone and the surrounding area without any defects. The developed filler material for welding surface defects (cracks, chips, etc.) formed during operation on aircraft engine bodies makes it possible to restore cast body parts and reuse them. The proposed filler material composition with an improved set of properties for the welding of body castings from Mg-Zr-Nd system alloy for aircraft engines makes it possible to increase their reliability and durability in general, extend the service life of aircraft engines, and obtain a significant economic effect.

“…The appropriate amount of REE significantly improves the wear resistance of the material, making the wear mechanism change from complex to simple abrasive wear. In the Mg-1.5Zn-0.6Zr alloy [93], the Vickers hardness increased from 54 HV to 60 HV, and the COF decreased from 0.132 to 0.127 as the addition of Sc element increased to 1.0 wt.%. The flaking phenomenon of the wear process is gradually weakened with the addition of Sc elements, and the wear surface gradually becomes smooth.…”

Rare earth elements (REEs) doping technology can effectively control the microstructure and improve the quality and performance of materials. This paper summarizes the research progress of REEs in metal additive manufacturing (MAM) in recent years and briefly introduces the effects of REEs on the molten pool fluidity, purified structure, and interfacial bonding between the molten cladding layer and substrate. It focuses on the mechanism of the role of REEs in the refinement and homogenization of microstructures, including grain growth, columnar to equiaxed transition (CET), and elemental segregation. The reasons for the influence of REEs on the homogenization of the structure and elemental segregation are analyzed. The effects of REE type, content, and dimension on hardness and wear resistance are investigated. Finally, tribological applications of REEs in biological and high-temperature environments are summarized, and the impact of REEs-modified alloys is summarized and prospected.

“…The machine learning (ML) methodology was adapted to predict the coefficient of friction (CoF) and wear rate. The dataset for the study was collected from various literature by considering operating temperature (⁰C), hardness of the workpiece and counterpart (HV), normal load (N), the weight percentage of Mg and REE (%) as input parameters and CoF and wear (mm 3 /Nm) as response variables [ [35] , [36] , [37] , [38] , [39] , [40] , [41] , [42] , [43] , [44] ]. For the purpose of comparison, the experimental wear rate in mg is converted into mm 3 /Nm.…”
