Microstructure and abrasive wear performance of chromium carbide reinforced Ni3Al matrix composite coating

Microstructure and tribological properties of Cr3C2/Ni3Al composite materials prepared by hot isostatic pressing (HIP)

“…Therefore, Ni 3 Al alloys are considered to be excellent materials for resisting wear at high temperatures. They have been used for tribological applications in which wear-resistance is the main requirement [8][9][10]. Recent studies have indicated that the high-temperature mechanical strength and hardness of Ni 3 Al alloys can be significantly improved by the addition of hard-particle reinforcements [11][12][13].…”

“…When present in iron, cobalt, and nickel matrices, chromium carbide exhibits high hot-hardness and excellent hightemperature oxidation resistance combined with good wetting ability [14][15]. Hence, chromium carbides are chosen frequently as hard-particle reinforcements for addition into Ni 3 Al-based matrices, to form Cr 3 C 2 /Ni 3 Al composites [8,16]. Cr 3 C 2 /Ni 3 Al composites have been widely investigated as wear-resistant materials in wear applications for many years.…”

Study on Wear Behaviors of Ni₃Al/Cr-Carbides Cladding Layer on High Strength Steel Substrate

“…%), the cladded layer clearly shows less contents of Ni, Al, Cr and C elements, but higher Fe content. Cladding process may result in loss of C and Al by oxidation [7] . It is obvious that the content deviations of Cr and Fe were initiated due to dilution during welding process.…”

Superior wear performances of one-step forming TiCp/Ni3Al-Ni3Al multi-coating on powder metallurgy master alloy substrate

“…To improve the wear performance of materials, coatings with superior wear resistance and higher operating temperature have been fabricated and investigated. 1,3,[9][10][11][12][13][14][15][16] Composites containing a high volume fraction of carbide, nitride, boride, or oxide particulates are usually selected for coating processing. As a typical intermetallic with high work-hardening capacity, nickel aluminide (Ni 3 Al) has been widely used in a variety of wear environments.…”

“…The re-precipitated tungsten carbide particles in the matrix made it possible to be used in severe wear condition. Li et al 11 examined the wear resistance of an Ni 3 Al composite reinforced by chromium carbide particles. They concluded that the presence of reinforced particles had a significant effect on improving the wear resistance of the monolithic matrix.…”
