“…Pressing, grinding, and polishing was conducted via TechPress 2™ and MetPrep 3™/PH-3™ (Allied High Tech Products, Inc., CA, United States) with 6 μm minimal grain size. The specimen was preliminarily etched for 9 s by 50 ml HCl + 50 ml C 2 H 5 OH + 2.5 g CuCl 2 [55][56][57][58][59][60][61][62].…”

“…Refinement of the grain structure: X.H. Wang et al [55] demonstrated the refinement of Fe-based composite coating after ultrasonic-assisted LMD, the disappearance of the columnar dendrites with 200 W ultrasonic power, and the appearance of the equiaxed dendrites with 400 W; C.J. Torado et al [56] also observed the grain refinement of 3D-printed Inconel 625 using the ultrasonic assistance, decrease of the epitaxial growth and improvement of homogeneity.…”

“…Increase of microhardness and wear resistance: X.H. Wang et al [55] showed that ultrasonic assistance increases the wear resistance of coating up to 2.4 times in comparison with a coating without ultrasonic assistance in the context of Fe-based composite LMD-fabricated coating deposited on the 5CrNiMo substrate. D. Zhang et al [57] observed the increase of microhardness from $380-450 HV1.0 to $435 … 515 HV1.0 at all levels of laser output power due to grain refinement and reduction of the porosity.…”

Direct energy deposition is a reliable additive manufacturing method of producing components with highly sophisticated geometry from a single material or combination of different materials with high manufacturing freedom and efficiency. The assembly operations are not required after the direct energy deposition: such complex parts as a rocket combustion chamber, a nuclear reactor element, a heat exchanger, and so on, could be fabricated layer-by-layer during one technological step. Promising applications are associated with Cu-Fe system laser deposited functionally graded components, which allow combining good oxidation resistivity, antifrictionality, thermal, and electrical conductivity of copper with mechanical strength, processability, and corrosion resistance of stainless steel. The main issue, which appears in the case of laser deposition of such materials, is internal stresses caused by significant inequality of physical properties of copper/bronze and steel, their limited miscibility, forming of brittle phases at the interface, and complexity of variation of mechanical and physical properties of the resulted alloy. The mentioned factors could cause various cracking in resulted parts. Specific techniques such as ultrasonic assistance, implementation of the external magnetic field, and post-treatment (hot isostatic pressing, machining), could be suggested to improve the quality of laser deposited Cu-Fe system functionally graded materials.

“…Ji [22] et al prepared the multi-coating amorphous alloy coating on 316 L stainless steel by a LC process, exploring the effects of different coating thickness on the friction properties. Wang [23] et al enhanced the Fe-based composite coatings by ultrasonic vibration, refining the grains to enhance the wear resistance. At present, the scholars mainly studied the effects of the dilution rates and process parameters of the laser cladding on the microstructure of Fe-based amorphous alloys [24][25][26].…”

The Fe-Cr-B-Si deposited layers were prepared on the titanium alloy by the laser melting deposition (LMD) or the laser cladding (LC) technology. The microstructure of the clad layer and the deposition bulk was characterized by the scanning electron microscopy, transmission electron microscopy and electron-backscattered diffraction. The single clad layer was primarily composed of the amorphous phase (APs), the fraction of APs decreased with increasing of the LMD layer thickness due to the heat accumulation, producing the crystalline phases. Parts of the nanocrystalline phases (NPs) were produced due to the characteristics of a laser-induced pool (LIP), producing the deposition bulk with the good metallurgy bond between the adjacent laser fabricated layers. The corrosion resistance of the deposition bulk was enhanced due to the production of the oxides and hydroxides, forming a passive film to enhance the corrosion resistance.
