Abstract
Ni-W-BN(h)-Si₃N₄ nanocomposite coatings were deposited on AISI 1045 steel using a traditional electrodeposition technique. The effects of BN(h) and Si₃N₄ nanoparticles on the performance of the coatings were investigated. Varying concentrations of Si₃N₄ nanoparticles were added to the bath of Ni-W-BN(h) nanocomposite coatings having an optimized concentration of BN(h) nanoparticles. The electrodeposited coatings were characterized using a laser scanning confocal microscope tester, scanning electron microscope, energy dispersive spectroscopy, x-ray diffraction, Vickers microhardness, and high-frequency reciprocating CFT-1 wear tester.
The results indicated that the peaks of the coatings were ascribed to (111) of FCC nickel-based solid solution. Ni, W, B, Si, and N elements were uniformly distributed in the coating. Ni-W-BN(h) coating fabricated with 6 g/L of BN(h) presented a hardness of 680.98 HV₀.₀₂₅ and a wear rate of 2.53 × 10⁻⁶ mm³·N⁻¹m⁻¹. Ni-W-BN(h) composite coating's microhardness and wear resistance were improved by maintaining the BN(h) concentration at 6 g/L and raising the Si₃N₄ concentration to 6 g/L. Ni-W-BN(h)-Si₃N₄ coating fabricated with 12 g/L of (BN(h) + Si₃N₄) presented the best microhardness (722.86 HV₀.₀₂₅) and wear rate (2.08 × 10⁻⁶ mm³·N⁻¹m⁻¹). The wear mechanisms of all coatings were studied.
