Study on Repairing Crankshaft With High Speed Nickel Brush Plating

The abradability of High Speed Nickel film was tested on MM200 wear test machine in this paper. Through single factor experiments and orthogonal experiments, the rules of effect of brush plating voltage and electrode relative velocity on film abradability were developed,the optimum parameters were obtained.The crankshaft brush plating procedure was formulated which was used for repairing a L195 diesel engine crankshaft.The durability of various operating mode was tested on a hydraulic dynamometer .The results showed that the abradability and unite strength of High Speed Nickel brushed crankshaft were improved, which can afford high speed heavy load. Repairing crankshaft with High Speed Nickel was reasonable in technique and economy, which provided basis for repairing crankshaft.
