| 摘 要： | 针对高效干切削和微量润滑加工中润滑能力不足的难题,通过引入石墨烯涂层自组装及界面优化,降低刀具表面自由能,提高刀具的耐磨性和寿命。采用DEFORM软件模拟不同切削速度下石墨烯涂层和非涂层硬质合金刀具切削加工6061铝合金,提取分析试验的切削力和切削热等数据后表明:在一定的切削条件下,石墨烯涂层能有效提高刀具的润滑性能,起到降低切削力和摩擦因数的作用。

| Abstract: | Aiming at the problem of insufficient lubrication ability in dry cutting and micro lubrication machining,it is expected to reduce the surface free energy and improve the wear resistance and life of the tool by using graphene coating self-assembly and interface optimization.Using DEFORM software to simulate the cutting of 6061 aluminum alloy with or without graphene coating and uncoated carbide tools under different cutting speeds,the data of cutting force and cutting heat are extracted and analyzed.The results show that graphene coating can effectively improve the tool's lubricity and reduce the cutting force and friction coefficient under certain cutting conditions,and introducing the mechanism of tool wear reduction. |
