The tribological properties of matrix and skeletal titanium carbonitride composites were studied in dry friction conditions in air. Experiments on wetting of the TiCN–Cr₃C₂ composite by nickel–chromium alloys and copper using the sessile drop method were performed to choose matrix composition and ascertain whether the samples could be produced by impregnation of the porous skeleton. The sessile drop experiments showed that nickel and its alloys formed a low contact angle on the TiCN–Cr₃C₂ composite (θ ≈ 8°). In particular, Ni3Al intermetallic had θ < 5°, allowing it to be used as a metal matrix. The same situation was observed for copper. A technique was developed for producing TiN–Cr₃C₂ composites by impregnation of the porous skeleton with Ni3Al and copper melts, and the tribological behavior of the cermets was tested in dry friction conditions. When the starting composite was impregnated with Ni₃Al intermetallic, the friction coefficient decreased (μ = = 0.25). Structural studies were conducted with a MIM-10 metallographic microscope and X-ray diffraction with a DRON-2 diffractometer. The hardness and contact area thickness were measured employing a Falcon 9 hardness tester (manufactured in the Netherlands). Thin cross sections were made to examine the structure and phase composition of the contact area. The structure was analyzed using X-ray diffraction and scanning electron microscopy. The effect exerted by hardness of the counterface (steel 45, 40Kh, ShKh15) on the tribological properties of the TiCN–Cr₃C₂ composite was established. When steel hardness was 60 HRC, the friction coefficient increased with friction distance. These results were, however, obtained at low speeds and loads. Friction losses decreased with loading increasing from 2 to 6 MPa at 12 m/sec: friction coefficient reduced to 0.23. The TiCN–20% Cr₃C₂ cermets impregnated with Ni₃Al may be recommended as antifriction materials for use in high-speed and high-load friction units.

在空气中的干摩擦条件下研究了基体和骨架碳氮化钛复合材料的摩擦学性能。进行了无柄滴落法用镍铬合金和铜润湿TiCN-Cr ₃ C ₂复合材料的实验，以选择基质成分，并确定是否可以通过浸渍多孔骨架来制备样品。无滴实验表明，镍及其合金与TiCN–Cr ₃ C ₂复合材料的接触角较小（θ≈8°）。特别是，Ni 3 Al金属间化合物的θ＜5°，因此可以用作金属基体。对于铜，观察到相同的情况。开发了生产TiN–Cr ₃ C _2的技术通过用Ni3Al和铜熔体浸渍多孔骨架制备复合材料，并在干摩擦条件下测试了金属陶瓷的摩擦学性能。当起始复合材料浸渍有Ni _3时铝金属间化合物，摩擦系数降低（μ= = 0.25）。用MIM-10金相显微镜进行结构研究，并用DRON-2衍射仪进行X射线衍射。使用Falcon 9硬度测试仪（在荷兰制造）测量硬度和接触区域的厚度。制成薄截面以检查接触区域的结构和相组成。使用X射线衍射和扫描电子显微镜分析结构。相对硬度（钢45、40Kh，ShKh15）的硬度对TiCN–Cr ₃ C ₂的摩擦学性能的影响复合材料成立。当钢的硬度为60 HRC时，摩擦系数随摩擦距离而增加。但是，这些结果是在低速和低负载下获得的。摩擦损耗随着载荷在12 m / sec下从2 MPa增加到6 MPa而降低：摩擦系数降低到0.23。可以推荐将浸渍有Ni ₃ Al的TiCN–20％Cr ₃ C ₂金属陶瓷用作高速和高负荷摩擦装置的减摩材料。
