| An Automatic High Velocity Arc Spraying Technology Applied to Remanufacture Engine Crankshaft |
|
|
| Abstract: |
| A 6R robot–based automatic high velocity arc spraying system was developed in this study. The remanufacturing process of engine crankshaft was designed based on the newly developed automatic spraying system and the FeAlNbB cored wire. The microstructure and properties of the coating prepared were investigated in lab. The results of industrial application in engine cylinder bodies shows that, both of the main shaft manetons and the crank manetons of the crankshaft can be deposited of coating in only one procedure using the developed automatic spraying technology, and a reliable quality of the remanufactured part was obtained. Furthermore, this technology has several advantages such as energy and material saving, and environmental protection, a wide application foreground for this technology is therefore performed. |
