Researchers at Agricultural University Report New Data on Ceramics (Effect of heat treatment on structures and corrosion characteristics of electroless Ni-P-SiC nanocomposite coatings)

By a News Reporter-Staff News Editor at Journal of Technology -- New research on Ceramics is the subject of a report. According to news reporting from Baoding, People's Republic of China, by VerticalNews journalists, research stated, "Ni-P-SiC nanocomposite coatings were successfully deposited onto mild steel substrates. The coating process was performed by sealing the specimens in an evacuated tempered glass tube and heated at various temperatures of 200 degrees C for 2 h, 400 degrees C for 1 h, and 600 degrees C for 10 min."

The news correspondents obtained a quote from the research from Agricultural University, "The effect of heat treatment on the structures and corrosion characteristics of the electroless Ni-P-SiC nanocomposite coatings was investigated by atomic force microscopy (AFM), X-ray diffraction (XRD), Vickers hardness, cyclic polarization, and electrochemical impedance spectroscopy (EIS) analyses. AFM and XRD results indicate that the optimum grain diameters of Ni and SiC in the as-plated Ni-P-SiC nanocomposite coatings are approximately 96.8 and 49.1 nm, respectively. The maximum microhardness for the as-plated Ni-P-SiC nanocomposite coatings is 968.3 HV. The highest microhardness is achieved for the samples heat treated at 600 degrees C for 10 min because of the precipitation of NixPy phases and the formation of an inter-diffusional layer at the substrate-coating interface."

According to the news reporters, the research concluded: "The lowest corrosion current density value is obtained for the coatings heat treated at 400 degrees C for 1 h. EIS data confirm these results."
