Research on functional gradient mold coating optimized preparation by electroplating and arc spray


Functional gradient tool (FGM) is an important developing direction of modern precision mould, it can effectively improve the performance and reduce the cost of die mould. On the base of the previous experiments, using electroforming and arc spray characteristics, through interactive experiment and analysis methods, to optimize the combination of two processes, complete the Ni-Zn metal alloy system structure / function gradient mold coating preparation, and complete analysis of coating micro structure. Experimental results and analysis show that, by melting casting and machining technology of arc spraying rapid manufacturing function gradient material mould is feasible, and can greatly improve the performance, reduce the cost of gradient mould precision, which will provide new ideas and methods to provide good for the preparation of functional gradient die precision.
