| Abstract |
Ni-P multilayer coatings were deposited on the surfaces of low-carbon steel by direct current electrodeposition through a stirring-time controlled technique (STT). The microstructure, hardness, friction coefficient and wear properties of the deposits were investigated. Scanning electron microscopy (SEM) in back-scattered electron mode revealed multilayer structures of Ni-P coatings fabricated by repeatedly turning the magnetic stirrer
in the bath on and off. Energy dispersive X-ray spectroscopy (EDS) was employed to quantitatively compare the P content in the alternating layers. The hardness of the Ni-P multilayer coatings was found to be significantly greater than that of monolithic Ni-P
coatings. A maximum hardness value of 580 ± 8.7 HV0.1 was found in the sample prepared using the on- and off-stirring periods of 8 and 15 min, respectively. This showed an increased hardness of 20.1% from that of sample prepared with the stirrer turned off. The
Ni-P multilayer coatings prepared by STT also had superior wear resistance to that of monolithic Ni-P coatings. |
