- 摘要:
- 采用电解-磁力复合研磨对Ti6Al4V钛合金板表面进行加工，研究了电解液温度和磁性研磨粒子粒径对表面加工质量和加工效率的影响。结果表明：当在电解液温度30 ℃下，采用粒径为185 μm的磁性研磨粒子对Ti6Al4V表面进行研磨25 min时，表面粗糙度Ra从原始的1.13 μm降至研磨后的0.12 μm，表面的残余应力从应力+187 MPa变为应力-57 MPa，试件表面的磨削纹理、凹坑、微裂纹缺陷被有效去除，且有利于零件表面疲劳寿命的改善。
- Abstract:
- The surface of titanium alloy Ti6Al4V plate was processed by electrolysis-magnetic force composite grinding. The effects of electrolyte temperature and magnetic abrasive particle size on the surface processing quality and machining efficiency were studied. The results showed that the surface roughness of Ra was decreased from the original 1.13 μm to 0.12 μm after 25 min grinding when the electrolytic temperature was 30 ℃ and the magnetic abrasive particle size was 185 μm. The surface residual stress was changed from +187 MPa to -57 MPa, and the specimen surface grinding texture, pits and micro-cracks were effectively removed which was beneficial to the improvement of the fatigue life of the surface.
