“…Orthorhombic chromium carbide (Cr 3 C 2 ) is a T m ~1800°C melting point refractory possessing a high degree of chemical stability and is widely used as a reinforcement in overlay welded coatings due to its high hardness [13]. In overlay welding, it typically melts and precipitates as hard hexagonal close-packed (hcp) Cr 7 C 3 and face centered cubic (fcc) Cr 23 C 6 or mixed M 7 C 3 and M 23 C 6 secondary carbides [14][15][16][17][18][19][20][21]. Chromium carbide reinforced overlay welded coatings have been developed, for instance, for cutting knives [22], nuclear reactor components [16], well drilling and oil extraction equipment [19], dies and molds [15], hot rolling mill rolls [20], and boiler tubes [23].…”

Fusion-bonded and low-diluted overlay welded coatings are frequently very thick (>1mm). High-speed laser cladding is a novel process capable of producing thin fusion-bonded and low-diluted coatings with high coverage rates and low heat input. In this study, for the first time, high-speed laser cladding was used to fabricate relatively thin Ni-based coatings reinforced with chromium carbides onto low-alloy structural and quenched and tempered steels. Obtained coatings were characterized with X-ray diffraction (XRD), optical (OM), and scanning electron microscopy (SEM), as well as electron backscatter diffraction (EBSD). Mechanical and wear properties were tested with Vickers microhardness measurements and three-body dry-sand rubber wheel abrasion tests (RWAT). It was shown that high-speed laser cladding produces 0.2–0.3-mm-thick coatings, which consist of ultrafine-substructured hypereutectic M7C3 structures reinforced with coarser primary Cr3C2 particles. Coatings with hardness up to 1300 HV0.05 exhibited high wear resistance in low-stress three-body abrasion. Coatings developed can be used as alternatives for hard-chrome plated coatings.

Cr3C2-Ni cermet is a kind of promising material especially for wear applications due to its excellent wear resistance. However, researches were mainly concentrated on the experiment condition of room temperature, besides high-temperature wear mechanism of the cermet would be utilized much potential applications and also lack of consideration. In present paper, the influence of Mo content on the high-temperature wear behavior of in-situ Cr3C2-20 wt. % Ni cermet was investigated systematically. The friction-wear experiment was carried out range from room temperature to 800 °C, while Al2O3 ceramic was set as the counterpart. According to experimental results, it is indicated that the coefficient of friction (COF) of friction pairs risen at the beginning of friction stage and then declined to constant, while the wear rate of Cr3C2-20 wt. % Ni cermet risen continuously along with temperature increased, which attributes to the converted wear mechanism generally from typical abrasive wear to severe oxidation and adhesive wear. Generally, the result of wear resistance was enhanced for 13.4% (at 400 °C) and 31.5% (at 800 °C) by adding 1 wt. % Mo. The in-situ newly formed (Cr, Mo)7C3 ceramic particle and the lubrication phase of MoO3 can effectively improve the wear resistance of Cr3C2-20 wt. % Ni cermet.
