Abstract

Amorphous Ni-P films with pretreatments, different electroless plating times, and magnetic field assistance are deposited onto brass plates and micro-journal bearings. X-ray diffraction results show that Ni-P films have an amorphous structure. X-ray photoelectron spectroscopy is used to investigate the bond structure and chemical composition. The hardness (H), coefficient of friction (CoF), corrosion behavior (E_corr), micro-journal bearing working life, and fatigue life of the Ni-P coated samples are obtained. The micro-magnetohydrodynamics effect induced by a magnetic field further improves the mechanical properties of Ni-P coatings. In a comparison between as-deposited and rotating magnetic field assistance electroless plating, the H, E_corr, and fatigue test results respectively increase from 6.78 to 8.62 GPa, from –0.546 to –0.234 V_SCE, and from 112.8 to 133.3 times. The CoF, wear rate, and micro-journal bearing wear decrease from 0.72 to 0.41, from 1.81 × 10^–6 to 1.25 × 10^–6 g/m, and from 1.50 to 0.88 mg, respectively.

期刊介绍： Thin Solid Films is an international journal which serves scientists and engineers working in the fields of thin-film synthesis, characterization, and applications. The field of thin films, which can be defined as the confluence of materials science, surface science, and applied physics, has become an identifiable unified discipline of scientific endeavor.
