“…In addition, Cr 3 C 2 can also be oxidized at high temperatures to produce oxides such as Cr 2 O 3 . 27,28 It not only efficiently improves the attachment of the coating with the substrate but also has excellent resistance to corrosion and stability. Cai and his colleagues used an in situ oxidation method on the 2205 duplex stainless steel surface to prepare a Cr 2 O 3 thin film, It was found that Cr 2 O 3 films showed excellent corrosion resistance in an acid−base environment.…”

“…Based on the above two phenomena, we found that Cr 3 C 2 ceramic materials are widely used in aircraft engines and petrochemical machinery devices because of their high hardness, which can greatly improve the life of machinery. However, there are relatively few studies on the doping of Cr 3 C 2 ceramic materials in composite coatings, especially there is no research on Cr 3 C 2 doping in Ni–P coatings. In addition, Cr 3 C 2 can also be oxidized at high temperatures to produce oxides such as Cr 2 O 3 . , It not only efficiently improves the attachment of the coating with the substrate but also has excellent resistance to corrosion and stability.

“…[3][4][5] The processing of TiAl alloys is highly constrained due to its weak ductility at room temperature, and its development and usage are also limited due to its long manufacturing cycle. [6] Recent advances and ongoing developments in additive technology have coincided with its increasing deployment in manufacturing, [7] and it has emerged as an ideal process for manufacturing titanium-aluminum alloys. [8] However, high manufacturing costs have greatly restricted the development of powder additive manufacturing (AM).…”

“…Fan et al [14] prepared TiC-and Cr 7 C 3 -reinforced laser-clad coatings on the surface of Ti6Al4V via preplacement of NiCr-Cr 3 C 2 powder. Aghili et al [15] observed numerous pores within NiCr-Cr 3 C 2 coatings on the surface of a titanium aluminide substrate prepared via laser cladding using a coaxial power supply.…”
