Abstract

Ti-6Al-4V has many applications in aerospace, medical devices, and other fields. However, the high hardness, high toughness, and low thermal conductivity of Ti-6Al-4V make it difficult to machine. In this paper, two ordinary textures and two combinatorial textures were designed on the surface of Ti-6Al-4V by laser ablation. Subsequently, form grinding experiments were conducted using a white corundum grinding wheel to compare the effects of untextured and different textures on the grinding performance of Ti-6Al-4V, including grinding force, surface morphology, surface roughness, edge morphology, and surface microhardness. The experimental results show that the grinding performance of workpieces with laser textures is all better than that of untextured workpieces. Among them, the combinatorial textured (DST1) workpieces showed the maximum reduction of tangential and normal forces by about 22 % and 29 %, respectively, the reduction of surface roughness by 20.1 %, and the increase of microhardness by 11.2 %. The results show that laser texturing of Ti-6Al-4V surfaces can improve grinding performance, enhance surface integrity, and realize efficient and low-damage machining.

激光组合表面织构协同改善钛合金成形磨削磨削性能

Ti-6Al-4V在航空航天、医疗设备和其他领域有许多应用。然而，Ti-6Al-4V的高硬度、高韧性和低导热系数使其难以加工。本文采用激光烧蚀法在Ti-6Al-4V表面设计了两种普通织构和两种组合织构。随后，利用白刚玉砂轮进行成形磨削实验，比较无织构和不同织构对Ti-6Al-4V磨削性能的影响，包括磨削力、表面形貌、表面粗糙度、边缘形貌和表面显微硬度。实验结果表明，经过激光织构处理的工件磨削性能均优于未经过激光织构处理的工件。其中，组合织构（DST1）的切向力和法向力最大降幅分别为22%和29%，表面粗糙度最大降幅为20.1%，显微硬度最大增幅为11.2%。结果表明，对Ti-6Al-4V表面进行激光织构可以改善其磨削性能，增强表面完整性，实现高效低损伤加工。
