摘要

摘要: 针对TiAl基合金塑性低、脆性大、表面可加工性差等问题，采用正交试验对TiAl基合金的砂带磨削表面完整性进行研究。总结归纳TiAl基合金砂带磨削材料去除率和表面质量的影响因素，通过灰色关联法得到正交试验的最优工艺参数为A3B3C2D2。采用最优工艺参数对TiAl基合金进行砂带磨削，分析TiAl基合金砂带磨削磨粒磨损过程，对磨削前后工件的表面形貌进行分析。结果表明砂带磨削对TiAl基合金的磨削加工效果好，可用于TiAl基合金表面的精密加工。本文研究为TiAl基合金表面精密加工提供了新的加工方法。

Abstract: In order to solve the low plasticity, high brittleness and poor surface processability of titanium-aluminum based alloy, the surface integrity in the process of TiAl based alloy abrasive belt grinding was studied with the orthogonal method. The factors influencing the material removal rate and surface quality of TiAl based alloy abrasive belt are summarized, and the optimal processing parameters is A3B3C2D2 by adopting the gray correlation method. TiAl based alloy abrasive belt grinding was carried out under the best technological parameters by analyzing the abrasive wear process of TiAl based alloy abrasive belt grinding and the surface topography of the workpiece before and after grinding. The result shows that the abrasive belt grinding has the good grinding effect on the TiAl based alloy, and it can be used in the precision machining of TiAl based alloy. The present work provides the new processing method for surface precision processing of TiAl based alloy.
