Research of micro-abrasive suspension jet erosion morphology and material removal mechanism
This paper introduces the micro-abrasive suspension jet polishing technology in precision machining technology.In order to understand the micro-abrasive suspension jet erosion morphology and material removal mechanism,the erosion experiments of micro-abrasive suspension jet on 40CrMnMo7 special steel work-piece were taken.We found that when the incident angles are 90°,60°,30°,the polishing area is respectively annular shape,horseshoe shape and blade shape.During the erosion process,as the incident angle becomes smaller,most amounts of abrasive particles impact angles will also be small,and these cause more material removal.When the particles impact the work-piece with small angles,most particles play sheafing action on the work-piece and leave the work-piece nano-scale scratches; while the particles impact the work-piece at large angles,extrusion and blow are formed by the majority of the particles on the work-piece,leaving different small size pits.
