钛合金作为我国战略发展的重要材料之一，在诸多领域得到广泛应用。然而，钛合金本身过低的弹性模量，过低导热系数和高温时较高的化学活性，使得钛合金加工常伴随过高的摩擦磨损和切削温度，导致切削刀具粘连严重甚至破损，对能源损耗，环境以及经济等问题产生巨大影响。新型MXene具备组分灵活可调、最小纳米层厚度可控、机械强度高、环境稳定性强、减摩抗磨性能优异等特点为钛合金难加工问题提供解决方案。本课题采用新型复合MXene基润滑液为研究对象，针对钛合金加工过程中的难加工问题，探究新型复合MXene基润滑液在钛合金加工中的自修复，抗磨，润滑，热传递等性能。对加工前后钛合金机械性能改善和加工刀具寿命等问题做出分析，揭示新型复合MXene基润滑液的在钛合金加工中超低磨损的存在条件和建立有限元理论模型。为钛合金等难加工材料在机械制造过程中所遇到的实际问题提供解决方案，在工程应用上有重要理论意义和应用价值。

Titanium alloy, as one of the significant materials, has been widely used in many fields. However, the low elastic modulus, low thermal conductivity and high chemical activity make the titanium alloy machining accompanied by high friction force, wear and cutting temperature, which is resulted in serious adhesion and even cutting tool damage. This phenomenon has a huge impact on energy consumption, environment and economy. Currently, the new MXene materials have excellent properties on the flexible components, controllable nano-layer, high mechanical strength, environmental stability and anti-wear performance, which provides a solutions for the machining of titanium alloy. In this project, a new composite MXene-based cutting fluid is synthesized to investigate the mechanism of titanium alloy processing, which content of the self-healing, anti-wear, lubrication and heat transfer. Further, other mechanical properties of the titanium alloy and tool-life after lubrication of the new MXene-based cutting fluid are explored. Reveal the existence of the ultra-low wear in machining titanium alloy in using new MXene-based cutting fluid. Finally, finite element theoretical model is set-up to give the credible technique supporting in industry.
