Naval ships are constructed with mild steel. Corrosion is a major concern in a marine environment. This particular type of material degradation has recently received more attention by the marine industry. Effort is make my researchers to combat this problem. In this work, co-deposition of Zn-ZnO-Ant hill powder composite coating on mild steel was reported with the view to combat this problem. The Ant hill powder was varied from 0 to 25 g. A 10 mL of orange juice was used as an organic additive. The coating thickness, surface roughness, microstructure, hardness values, wear rate and potentiodynamic polarization in simulated sea water were determined. The addition of orange juice as an additive changed the morphological and texture of the coating, and the hardness values, wear and corrosion rate were enhanced. Maximum corrosion protection efficiency of 92.86% and 94.41% was obtained at Zn-ZnO-25gAnt hill and Zn-ZnO-25gAnt hill + orange juice, respectively. The work has established that Zn-ZnO-Ant hill powder composite coating on mild steel is promising.

This paper presents the anti-wear and hardness values of electrodeposited Zn-ZnO- XRHA composite coating. Chloride-based bath was employed for the deposition bath. The deposition parameters were 0g, 10g and 20g rice husk ash (RHA) particulate loading, 15 minutes deposition, 1.4A current, 400 rpm stirring rate and 75℃ bath temperature. The composition, morphology, occurred phases, hardness and wear resistance for the RHA, mild steel substrate and developed coatings were studied. Equipment used for analyzing the coatings properties were x-ray fluorescence spectrometer, scanning electron microscope (SEM) with attached energy dispersive spectrometer (EDS), X-ray diffractometer (XRD), EMCO Test Dura-scan microhardness tester and CERT UMT-2 tribological tester. Results showed that the Zn-ZnO-20RHA coated substrate had the highest hardness result toping the bare substrate by about 170% increment value. The trend of the wear loss for the developed Zn-ZnO-XRHA descended relative to increased particulate loading.

Hardness Values

Ni–Co–P/Si3N4 composite coatings were fabricated over an aluminum–silicon (Al–Si) substrate using a pulse-current electroplating process, in which the rapid deposition of an intermediate nickel–cobalt layer was used to improve coating adhesion. The microstructure, mechanical, and tribological behaviors of the electroplated Ni–Co–P/Si3N4 composite coating were characterized and evaluated. The results revealed that the electroplated Ni–Co–P/Si3N4 composite coating primarily consisted of highly crystalline Ni–Co sosoloid and P, and a volumetric concentration of 7.65% Si3N4. The electroplated Ni–Co–P/Si3N4 composite coating exhibited hardness values almost two times higher than the uncoated Al–Si substrate, which was comparable to hard chrome coatings. Under lubricated and dry sliding conditions, the electroplated Ni–Co–P/Si3N4 composite coating showed excellent anti-wear performance. Whether dry or lubricated with PAO and engine oil, the composite coating showed minimum abrasive wear compared to the severe adhesive wear and abrasive wear observed in the Al–Si substrate.
