Abstract:

A novel electroforming technique with flexible squeeze of brush
 was proposed.During the electroforming process,the quality of deposits was improved by
squeeze and rob of the flexible brush.The morphology of the deposits was studied,
and the values of microhardness were also measured.The results show that,
the rub with flexible brush can remove the adhered bubbles effectively and eliminate the
surface nodules,and improve the surface quality of the deposits.Comparing with the
deposits prepared by traditional methods,SEM results show that the one prepared by
the novel technology is substantially refined with grain size,and XRD results show that
every diffraction peak's intensity of the deposit is reduced.The microhardness increases evidently from 180HV to about 400HV.
