Limitations and constraints of traditional electroplating
(1) environmental requirements: Cr6+ carcinogenic, electroplating wastewater pollution of the environment.
(2) performance requirements: it cannot meet the working condition of high temperature and wear resistance,
and hydrogen embrittlement exists.
(3) slow deposition rate of electroplating process;The dimension of electroplated workpiece is limited by the
dimension of plating groove.
