摘要
基于阀芯端帽的外形特征及磨损状况,对阀芯端帽工作面激光合金化的扫描路径进行规划。根据实际使用中阀芯端帽工作面上不同的磨损状况将其划分为三个区域,设计双向螺旋式扫描路径,实现阀芯端帽工作面上不同区域的合金化面积比不同。使用NdYAG激光器进行编程加工,将采用双向螺旋式扫描路径的试件与采用直纹式扫描路径的试件分别进行磨擦实验。研究发现,采用双向螺旋式扫描路径时,阀芯端帽工作面的耐磨性能是直纹式扫描路径的2.5倍,而变形量约为直纹式扫描路径的1/3。
Abstract
The scanning path of laser alloying on the working surface of valve core end caps is programmed based on its shape characteristics and wear conditions. According to the different wear statuses in actual working surface, the working face of valve core end caps is divided into three alloying areas. And a bi-directional spiral path is designed in order to achieve those different areas with different alloying area ratios on the working surface. Subsequently, NdYAG laser device is utilized to achieve programming machining, and the fabricated samples are tested in wear test separately with bi-directional spiral scanning path and straight scanning path. It is observed that the wear-resisting property of the working surface of the valve core end caps scanned through bi-directional spiral path is 2.5 times different when scanned by straight scanning path, and its deformation is just about one third of the samples which are scanned by straight scanning path.
