    摘要:

    对TA2工业纯钛成功实现了搅拌摩擦加工(Friction Stir Processing, FSP),研究FSP后搅拌区、热机影响区、热影响区组织特征,对比分析FSP加工区与母材的显微硬度及摩擦磨损性能。结果表明:TA2工业纯钛表面经FSP后,搅拌区晶粒发生了剧烈的塑性变形、混合和破碎,实现组织结构的致密化、均匀化和细化;加工区平均硬度相对母材提高37.5%,当摩擦磨损圈数分别为1000、1500、2000 r时,摩擦磨损质量损失分别比母材减少31.4%、36.6%和46.4%,经FSP后TA2工业纯钛表面硬度和抗摩擦磨损性能明显提高

    Abstract:

    Friction stir processing (FSP) for TA2 commercially pure titanium was performed. The microstructure characteristics of the stir zone, the thermo-mechanically affected zone and the heat affected zone were investigated. The hardness and wear properties of the base material and the friction stir procession specimen were analyzed contrastively. The results indicate that in the surface of TA2 commercially pure titanium after FSP, the grains of the stir zone undergo plastic deformation, blending and breaking to realize the densification and homogenization of the microstructure. The microhardness of the stir zone is increased by 37.5% compared with that of the base material. When the abrasive wear cycle is 1000, 1500 and 2000 r, the abrasion loss of the stir zone is smaller than that of the base material by about 31.4%, 36.6% and 46.4%, respectively. The microhardness and wear properties of the TA2 commercially pure titanium are greatly improved
