显微组织对掺钾钨杆机加性能的影响
|
摘要
制备了两种不同显微组织的掺钾钨杆,并通过金相分析、硬度检测等方法研究了显微组织对掺钾钨杆机加性能的影响。结果表明:改进型钨杆的整体硬度较低且其硬度的稳定性优于普通型钨杆;改进型钨杆车削后的表面平整光洁,粗糙度为Ra0.430μm,优于普通型钨杆;改进型钨杆车削后的刀损值为普通型钨杆刀损值的46%。由此可证明改进型钨杆具备硬度低和显微组织均匀等特性,机加性能优异。
Two kinds of K-doped tungsten rods with different microstructures were prepared. The effects of microstructures on the machining performance of K-doped tungsten rods were studied systematically. The results show that the overall hardness of the tungsten rod with improved microstructure is lower, and the stability of its hardness is better than that of the tungsten rod with ordinary microstructure. After turning test, the surface of the tungsten rod with improved microstructure is smooth and bright, and the roughness Ra is 0.430μm, better than that of tungsten rod with ordinary microstructure; the tool loss value of the tungsten rod with improved microstructure is 46 % less than that of tungsten rod with ordinary microstructure.The tungsten rod with improved microstructure has characteristics of low hardness and homogeneous microstructure, with excellent machining performance.
