电解磁力复合加工对磁性磨粒性能的影响
Effect of electrolytic magnetic composite machining on properties of magnetic abrasive particles
摘要
Abstract
When the nickel base superalloy and other materials are machined by simple magnetic grinding process,the failure of magnetic abrasive particles seriously affect the grinding effect of the magnetic grinding process.In order to solve this technical problem,electrochemistry is combined with the abrasive finishing technology.Eelctrolytic processing is used to form a softer passivation film on the workpiece,and then the surface is machined by magnetic abrasive finishing.The compositions of the magnetic abrasive particles after the composite processing are analyzed by electron microscopy,the relative mass fraction of aluminum decreases from 27.60 ％ to 23.48 ％.It effectively reduced the loss of abrasive phase components in magnetic abrasive grains,delags the failure time and improves the utilization and service life of magnetic abrasive grains,thus ensures the machining quality of workpieces.关键词
