Improved acrylonitrile-butadiene-styrene surface properties via electroless (NiP-SiC) nanocomposite coating

Abstract

By using electroless nickel-phosphor plating techniques, several (NiP-SiC) nanocomposite coatings were applied to acrylonitrile-butadiene-styrene (ABS) substrates at different temperatures and deposition times. Field emission scanning electron microscope (FESEM) images show that different coating morphologies have been produced. The energy-dispersive x-ray spectroscopy (EDX) data demonstrate that the (NPs) were successfully integrated and nickel and phosphorus are the principal components of the coating. The nickel peaks have been noticed at an angle around (43.29⁰) which belongs to Ni (111) using an X-ray diffraction analysis (XRD) pattern for (NiP-SiC NCCs) produced under different immersion times and temperatures. The nanocomposite coating that was made at 95 °C for 30 min showed the best hydrophobic properties, with a maximum contact angle value of (119.68°), according to the contact angle data. The corrosion behavior was studied via the electrochemical method in (3.5 wt.%) NaCl at (25 °C), and the results showed that the best polarization resistance for the (NiP-SiC) coating is obtained at (90 min at 75 °C) deposition conditions and is (45.14222 kΩ. cm) which produce complete coverage compact coating with growth globular. The best hardness value recorded for a coating that has the most nucleation sites came from a high incorporation nanoparticles level with a small nodule structure which formed at (30 min and 75 °C) and is (3.15 GPa). Finally, the lower wear rate value was collected for the coating having the lower coefficient of friction which was produced at (30 min at 75 °C) deposition conditions and is (0.023 mg/m)).
