Structure, morphology and mechanical properties of electrodeposited composite coatings Ni–P/SiC [PDF]
, 2010 Physical properties of the NiP/SiC deposits are discussed according to the electroplating parameters and heat treatments. The insertion of silicon carbide in the coatings does not modify their rigidity (E = 230 GPa), increases their hardness slightly (50
