摘要: 镍基高温合金加工过程易产生表面损伤,且服役性能对表面纹理和缺陷具有强相关性。同时,复杂载荷状态对构件表面提出了各向同性加工需求。融合砂带磨削柔性、低损伤特点和超声辅助加工纹理优化优势,提出了二维超声辅助砂带磨削方法。分析了不同工艺参数下磨粒运动轨迹,基于单颗粒划擦试验分析了超声方向、振幅和相位对材料去除行为的影响,并揭示了工艺参数对GH4169表面完整性及其均匀性的影响规律。结果表明:二维超声辅助砂带磨削具有较好的纹理优化效果,同时可以获得均匀塑性变形层。通过相位调控可以制备出类网状纹理,抑制了表面完整性各向异性。相位差90°时表面完整性及分布一致性较好,其中较大振幅可以提升表面残余压应力、降低表面粗糙度。纹理优化和材料去除之间存在竞争机制,较低进给速度可以获得较小表面粗糙度和较大残余压应力。

Abstract: Nickel-based superalloys are prone to surface damage during machining, and its service performance has strong correlation with surface texture and defects. Meanwhile, complex load puts forward isotropic processing requirements. Combining flexible and low damage of belt grinding and texture optimization of ultrasonic-assisted machining, two-dimensional ultrasonic-assisted belt grinding method is proposed. The abrasive trajectory under different parameters is analyzed, and the influence of ultrasonic direction, amplitude and phase on material removal is analyzed based on single-particle scratch test. The influence of process parameters on surface integrity and uniformity of GH4169 is also revealed. Results show that two-dimensional ultrasonic-assisted belt grinding has texture optimization effect, and can obtain uniform plastic deformation layer. Reticulum-like texture can be prepared and the anisotropy of surface integrity can be suppressed. Phase difference of 90°improves surface integrity and consistency. Large amplitude can increase residual compressive stress and reduce surface roughness. Low feed speed result in small roughness and large residual compressive stress.
