The effects of autocatalyst copper coating of SiCp on the microstructure of CuSiCp composites
(Universiti Malaysia Perlis, 2009-12-01)
In this paper, the autocatalyst copper coating (ACC) of silicon carbide particle
(SiCp) was performed after a sequence of surface treatment, sensitization and
surface activation processes. The ACC process was operated ...
