摘要

Inconel 718因其热机械性能广泛应用于航空航天领域，但加工过程中导致刀具快速磨损。本研究开发了一种共价金刚石-纳米石墨烯（CDGG）工具，使用纳秒激光和飞轮解理将sp³金刚石转化为sp²石墨烯，将其焊接到硬质合金手柄上，并使切削刃更加锋利。摩擦磨损试验和切削实验表明，CDGG刀具的表观摩擦系数比金刚石刀具低49 ~ 59%，前刀面磨损深度比金刚石刀具低55 ~ 65%，比陶瓷刀具低75 ~ 85%。石墨烯形成自润滑层，最大限度地减少磨损，提高Inconel 718的加工效率和刀具耐用性。

Improving cutting performance of nickel-based alloy by graphene modified diamond tools

Inconel 718 is widely used in aerospace due to thermomechanical properties, but machining causes rapid tool wear. This study develops a covalent diamond-nanographite-graphene (CDGG) tool using nanosecond lasers and flywheel cleavage to convert sp³ diamond into sp² graphene, welds it onto a carbide handle, and sharpens cutting edges. The friction-wear tests and cutting experiments show that CDGG tool’s apparent friction coefficient is 49–59 % lower than diamond tool, rake face wear depth is 55–65 % lower than diamond tool, 75–85 % lower than ceramic tool. Graphene forms self-lubricating layers, minimizes wear, and enhances Inconel 718 machining efficiency and tool durability.
