【摘要】 电火花沉积可制备硬度高、耐磨性和耐腐蚀性优异的强化涂层,能显著提高机械零部件的性能和使用寿命,传统电火花沉积主要依靠人工操作。基于Labview开发平台设计了一套电火花自动沉积监控系统,其硬件主要由PC机、Arduino控制卡、步进电机等组成,该系统具有运动控制、运动反馈、数据采集、沉积轨迹设置和显示等功能,并在沉积路径规划中加入了Bresenham算法,实现了电火花沉积过程的自动控制。更多还原

【Abstract】 Electrospark deposition(ESD)can be used for preparing strengthened coatings with high hardness,excellent wear resistance and excellent corrosion resistance,which can significantly improve the performance and service life of mechanical parts. However,traditional ESD mainly relies on manual operation. In this paper,a set of ESD automatic deposition monitoring system is designed based on Labview as a development platform,and the hardware of the system is mainly composed of a PC,an Arduino control card,a stepper motor and the like. The system has the functions of motion control,motion feedback, data collection,deposition track setting,display and the like. The Bresenham algorithm is added to a deposition path,and therefore the automatic control over an ESD process is realized.更多还原
