Flat jet electrochemical milling of TC4 alloy with tailoring backward parallel flow

引用

Chinese Journal of Aeronautics 2024年第4期37卷 574-592页

作者： Huanghai kong Ningsong QU College of Mechanical and Electrical Engineering Nanjing University of Aeronautics and AstronauticsNanjing 210016China

In flat jet electrochemical milling, the electrolyte forms a backward parallel flow after impacting the workpiece, resulting in a weak current density distribution on the workpiece. Poor surface quality usually occurs on the machined titanium alloy surface because it inevitably suffers from the weak current density. In this study, a method of flat jet electrochemical milling with tailoring the backward parallel flow was proposed to eliminate the negative effects caused by the weak current density. Multiphysics simulations are carried out to comprehend the mechanism of flat jetEC milling with tailoring backward parallel flow and better construct the novel tool *** on flat jet electrochemical milling of TC4 alloy with and without tailoring backward parallel flow are conducted. The results reveal that, compared with flat jet electrochemical milling without tailoring backward parallel flow, the recommended tool reduces the surface roughness by86% to 93%, and improves the material removal rate by 93% to 163% with different feed ***, the recommended tool is more conducive to maintaining the inherent hardness of the material. Finally, a surface with low Sa of 0.37 μm is obtained.

AIM: To discuss the long-term postoperative results of bilateral lateral rectus recession(BLR) and unilateral lateral rectus recession-medial rectus resection(RR) in therapy of intermittent ***: We retrospectively analyzed 213 cases of intermittent exotropia who underwent surgery between2008 and 2010. The patients were grouped into BLR group and RR group. Motor outcomes were divided into three groups on the basis of the angle of deviation after surgery: overcorrection(esotropia/phoria >5△), orthophoria(esotropia/phoria ≤5△to exotropia/phoria ≤10△), and undercorrection/recurrence(exotropia/phoria >10△).Titmus test was used to evaluate stereoacuity, the stereoacuity 0.05) between ***, the motor outcomes at 6, 36 mo were signally different in each group, indicating the success rate in RR group at 6mo was higher than that in BLR group(83.02%vs 82.24%, P <0.05) but the result was contrary at the 3y examination(60.75% vs 43.40%, P <0.05). No statistical significance were found in the sensory outcomes between the groups at mean of 3.7y ***: The motor outcomes in RR group were better than in BLR group at 6mo after surgery, while the3 y outcomes were better in BLR group. This may be due to the recurrence rate of the BLR was lower than the RR group’s.
