Carbon nanotubes (CNTs) with superior properties were introduced for the first time into Fe-TiB₂ cermet coating to strengthen its wear resistance. Initially, composite feedstock in which every powder was not only highly spherical and dense but also contained uniform CNTs and TiB₂ were successfully prepared. Then, Fe-based metallic and Fe-TiB₂ cermet coating with or without CNTs were deposited via high velocity air fuel (HVAF) to mainly investigate the effect of CNT addition on the microstructure and wear behavior of coatings. It shows that, with incorporation of 2.5 vol% CNTs, the coating microstructure became denser and the microhardness and fracture toughness of Fe-TiB₂ cermet coating obtain increases of 32% and 44% (or 61%). As a result, the improved tribological properties, the lowest porosity and fewest wear crack contribute to its best wear resistance with specific wear rate of 2.47 × 10⁻⁶ mm³/N·m. Oxidative and mild abrasive wears rather than severe adhesive wear were the dominant wear mechanism of coating reinforced by CNTs.

首次将具有优异性能的碳纳米管（CNTs）引入Fe-TiB ₂金属陶瓷涂层中，以增强其耐磨性。最初，成功地制备了复合原料，其中每种粉末不仅高度球形且致密，而且还包含均匀的CNT和TiB ₂。然后，通过高速空气燃料（HVAF）沉积具有或不具有CNT的Fe基金属和Fe-TiB ₂金属陶瓷涂层，主要研究CNT添加对涂层的微观结构和磨损行为的影响。结果表明，加入2.5％（体积）的碳纳米管后，涂层的组织变得致密，Fe-TiB ₂的显微硬度和断裂韧性金属陶瓷涂层的增加量为32％和44％（或61％）。结果，改善的摩擦学性能，最低的孔隙率和最少的磨损裂纹有助于其最佳的耐磨性，比磨损率为2.47×10 ^-6  mm ³ / N·m。碳纳米管增强涂层的主要磨损机理是氧化性磨损和轻度磨料磨损，而不是严重的粘合剂磨损。
