TiAl基合金砂带精密磨削表面完整性研究
Research on Surface Integrity in Precision Abrasive Belt Grinding of TiAl based Alloy
摘要
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 presem work provides the new processing method for surface precision processing of TiAl based alloy.关键词
