“…The two most frequent current profiles at PCP are the periodically interrupted current (PIC), in which the current is a unidirectional square-wave, and the periodic reverse current (PRC), where a bidirectional square waves is used. Compared with the CCP technique, the PCP technique has more advantages [4]. Grounded on above analyses and considerations, the paper adopted the electrodeposition methods (CCP and PIC) to synthesize the TiB 2 coating on the graphite substrate, for the thermal expansion coefficient (4.3 Am/m/-C)of graphite is close to that (4.6 Am/m/-C) of titanium diboride [5].…”
