| 目的 研究钛合金表面TiB2涂层在高温条件下与工业纯铝之间的黏着磨损行为，重点分析了不同滑动速度对其影响。通过实验探讨TiB2涂层的抗铝黏着磨损规律及其作用机制，为提升涂层的高温耐磨性能提供理论依据。方法 采用直流脉冲磁控溅射工艺在TC4钛合金表面制备具有致密结构和优异膜基结合强度的TiB2涂层，使用高温销-盘摩擦磨损试验机，探究滑动速度对钛合金表面TiB2涂层与工业纯铝之间黏着磨损行为的影响，揭示涂层在不同速度条件下的磨损特性及其抗铝黏着性能的变化规律。采用扫描电子显微镜、三维超景深光学显微镜和接触式轮廓仪表征涂层与铝销表面磨痕形貌特征和磨损状态，并对摩擦学系统的铝黏着磨损转移程度进行定量计算。结果 在300 ℃高温下，随滑动速度提高，摩擦因数降低，TiB2涂层磨痕内部的铝黏着转移层形貌发生变化，由连续的岛状丘状片层逐渐转变为分散的颗粒状锚点。同时，铝黏着转移层的平均厚度和覆盖率明显减小，表明滑动速度对铝黏着行为具有显著影响。此外，基于TiB2涂层表面铝黏着转移程度与纯铝销磨损量提出归一化的涂层抗黏着能力系数Ac，其可反映滑动速度对TiB2涂层抗铝黏着转移能力的影响。随滑动速度升高，TiB2涂层将体现出更加优异的抗铝黏着转移特性，抗铝黏着能力系数由0.05 m/s时的0.917降低至0.30 m/s时的0.058。结论 300 ℃高温下TiB2涂层能够抑制铝的黏着转移行为。随滑动速度的升高，工业纯铝销对TiB2涂层表面铝黏着转移层的剪切去除作用增强，因此TiB2涂层表面铝黏着转移程度降低。 |

| In the low-pressure compressors of aero-engines, titanium alloy blade tips are prone to high-speed rubbing against aluminum-based sealing coatings. This rubbing often results in aluminum-adhesive transfer, which can degrade the performance and lifespan of the aero-engine. To address this issue, the work aims to deposit TiB2 coatings on titanium alloy blades to achieve efficient cutting and resistance to aluminum-adhesive transfer. The introduction of TiB2 coatings could provide a hard and wear-resistant surface that minimizes material transfer and maintains the integrity of the blade tips. Furthermore, the interaction in the tribological system is significantly affected by loads, temperature, and sliding speed. Therefore, the adhesive wear behavior between TiB2 coatings and aluminum at high temperatures under varying sliding speed is investigated, highlighting the mechanisms and effectiveness of TiB2 coatings in resisting aluminum adhesive wear. The dense-structured TiB2 coatings were prepared on TC4 titanium alloy surfaces through pulsed-DC magnetron sputtering. The sputtering parameters included a pressure of 0.5 Pa, a target-substrate distance of 100 mm, a sputtering power of 500 W (with a duty cycle of 90% and a frequency of 40 kHz), a substrate bias of ‒60 V, and a deposition time of 90 minutes. The as-deposited TiB2 coatings had an excess boron chemical ratio (B/Ti = 3.91) and a thickness of 1.1 μm, with hardness and elastic modulus at 34.4 GPa and 431.2 GPa, respectively. A high-temperature pin-on-disk tribometer was utilized to examine the effect of sliding speed on the adhesive wear behavior between TiB2 coating and aluminum. The surface characteristics and wear states of the coatings and aluminum pins were analyzed with a scanning electron microscope, a 3D super-depth optical microscope, and a contact profilometer. The aluminum-adhesive transfer in the tribological system was quantitatively assessed. At elevated temperatures (300 ℃), the TiB2 coating effectively suppressed Al-adhesive transfer. As the sliding speed increased from 0.05 m/s to 0.30 m/s, the coefficient of friction decreased from 0.55 to 0.14. Simultaneously, the shear removal effect of the aluminum pin on the aluminum adhesion transfer layer of TiB2 coating increased, reducing the extent of aluminum transfer on the TiB2 coating. The morphology of the Al-adhesive transfer layer within the wear tracks of the TiB2 coating transitioned from continuous islands to particulate anchors, decreasing the average thickness and coverage of the aluminum transfer layer. Plastic smearing and shear tongues were observed on the edges of the aluminum pin. A normalized anti-adhesive capability coefficient (Ac) was proposed, based on the degree of Al-adhesive transfer on the TiB2 coating and the wear of the pure aluminum pin, to reflect the effect of sliding speed on the anti-adhesive performance of TiB2 coatings. As the sliding speed increased, the TiB2 coating demonstrated superior resistance to aluminum-adhesive transfer, with the anti-adhesive capability coefficient decreasing from 0.917 at 0.05 m/s to 0.058 at 0.30 m/s. |
