High Velocity Arc Spraying for Automotive Industry
A diesel engine crankshaft is failed in journal and the dominant failure mechanism is wear. A 6R robotbased 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 two spraying way planning were designed. The results of industrial application in miniature show that, both of the main shaft journal and the crank journal of the crankshaft can be deposited of coating in only one procedure using the developed automatic spraying technology, and a reliable quality remanufactured part was obtained. A comparative evaluation shows that the improvement process offers several benefits. Such as, the coating bond strength and spray rates are all highly increased; the remanufactured cost and time are decreased. Furthermore, this technology has several advantages such as energy and material saving, and environmental protecting, a wide application foreground for this technology is therefore performed.
