The carbonyl cladding method was employed to produce metal–ceramic TiCrC(Ni) composite powders from double titanium–chromium carbide with 17, 25, and 33 wt.% Ni. To deposit coatings through the plasma, detonation, and high-velocity oxygen fuel spray processes, powder materials of different size fractions, μm, were produced: −80+40, −63+40, and −40+20, respectively. The composite TiCrC(Ni) powder particles were of irregular shape and consisted of a refractory core with 18–26 GPa microhardness, surrounded by a ductile nickel layer. Electron microprobe analysis revealed that the ceramic core included two phases: main TiCrC phase and interspersed Cr₇C₃ phase. The nickel layer deposited on the titanium–chromium carbide particles became thicker with higher nickel content of the TiCrC(Ni) composite powders and varied from 0.5 to 4 μm. The effect of nickel content on the service properties (apparent density and flowability) of the developed powders was determined. The apparent density of the TiCrC(Ni) powders was not found to substantially depend on their particle size or nickel content and was 2.3–2.6 g/cm³ on average. The flowability of the TiCrC(Ni) powders was found to depend on their particle size and nickel content. The flowability of the TiCrC(Ni) powders improved with increasing particle size and was 41.2–51.4 sec for the −63+40 μm powders and 40.2–47.0 sec for the −80+40 μm powders. The −40+20 μm TiCrC(Ni) powders for oxygen fuel spraying had very poor flowability and thus could be used only for coating deposition units with forced powder supply to the spray area. Their flowability became higher with nickel content of the TiCrC(Ni) composite powders increasing from 17 to 33.5 wt.%.

采用羰基包覆法从含 17、25 和 33% 重量的镍的双钛-碳化铬制备金属-陶瓷 TiCrC(Ni) 复合粉末。为了通过等离子体、爆炸和高速氧燃料喷涂工艺沉积涂层，生产了不同尺寸分数 μm 的粉末材料：分别为 -80+40、-63+40 和 -40+20。复合 TiCrC(Ni) 粉末颗粒形状不规则，由显微硬度为 18-26 GPa 的耐火芯组成，周围是可延展的镍层。电子探针分析表明，陶瓷芯包括两相：主要的 TiCrC 相和散布的 Cr ₇ C ₃阶段。随着 TiCrC(Ni) 复合粉末镍含量的增加，沉积在钛 - 碳化铬颗粒上的镍层变得更厚，从 0.5 到 4 μm。确定了镍含量对所开发粉末的使用性能（表观密度和流动性）的影响。未发现 TiCrC(Ni) 粉末的表观密度基本上取决于它们的粒径或镍含量，为 2.3–2.6 g/cm ³一般。发现 TiCrC(Ni) 粉末的流动性取决于它们的粒径和镍含量。TiCrC(Ni) 粉末的流动性随着粒径的增加而提高，-63+40 μm 粉末为 41.2-51.4 秒，-80+40 μm 粉末为 40.2-47.0 秒。用于氧气燃料喷涂的-40+20 μm TiCrC(Ni)粉末流动性非常差，因此只能用于喷涂区域强制供粉的涂层沉积装置。随着 TiCrC(Ni) 复合粉末的镍含量从 17% 增加到 33.5%，它们的流动性变得更高。
