“…It is possible to provide a more favorable combination of strength, ductility, and fracture toughness of coatings based on Ti-Cu intermetallic compounds by introducing additional phases into the coating composition and thus dispersing the structure [6][7][8][9][10]. For example, it is known that alloying Ti-Cu intermetallic compounds with Ni helps to increase their ductility, and when its content is 15-20%, a shape memory effect appears.…”

The diffusion processes during the contact melting at the boundary of explosively welded VT1-0 titanium with CuNi19 (melchior) and CuNi45 (constantan) alloy composites were studied. Heat treatment of composites led to the formation of the interaction zone at the joint boundary. The interaction zone in VT1-0 + CuNi19 consists of TiCuNi and αTi + Ti2Cu(Ni) continuous layers as well as a mixture of TiNi(Cu) + TiCu(Ni) + Ti2Cu(Ni) intermetallics. It has been shown that an increase in the nickel content in the case of VT1-0 + CuNi45 composite leads to a decrease in the temperature of contact melting, a change in its mechanism, an increase in the titanium content in the interaction zone, and the appearance of additional Ti2Ni(Cu) intermetallic in its composition.

“…Much research [11,12] has been focused on composite treatment techniques combining mechanical and thermochemical surface modifications, but for many workpieces experiencing wear, these approaches cannot achieve the desired mechanical improvements. Therefore, composite thermochemical surface modification [13][14][15][16][17][18] is a more promising approach. Vacuum carburizing is superior to conventional carburizing in terms of throughput, control lability, surface property enhancement, etc.…”

In this study, the responses of 20CrNi2Mo steel to carburizing (C) and carburizing-nitriding (C+N) duplex treatment and the effects of these treatments on the friction and wear properties were systematically studied. The 20CrNi2Mo surface layers were characterized by optical microscopy (OM), laser scanning confocal microscopy (LSCM), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Vickers microhardness tests and high-speed reciprocating friction and wear testing. The results showed that after the carburizing and nitriding duplex treatment, an approximately 5 μm-thick compound layer (CL) consisting of the γ′-Fe4N and ε-Fe2-3N phases had formed on the surface, and the diffusion layer depth was approximately 220 μm. The carbides (MC) stored during carburizing were easily converted to nitrides (MN) during the nitriding process. Furthermore, the surface microhardness (879 HV) was increased by a factor of 2 compared with the substrate (420 HV), the surface residual compressive stress (-652 MPa) was increased significantly, and the surface roughness also increased. Wear analyses under different loads showed that specimen C exhibited the worst wear resistance, and its wear mechanism was mainly abrasive wear. The C+N with CL samples showed excellent wear resistance under a 20-N load; after removing the CL samples (C+N with CL), they showed excellent wear resistance under a 40-N load, and the wear mechanism was mainly adhesive wear. This work showed that the wear resistance was improved significantly by the carburizing and nitriding duplex treatment, but the CL had different effects on the wear performance under different loads.
