Summary: Ni/WC-MoS2 composite coatings were fabricated using jet electrodeposition in electrolytes with different MoS2 doping levels. The surface characteristics, including composition, morphology, microhardness, and tribological behavior, were investigated. The results showed that Ni/WC-MoS2 coatings exhibited better surface quality, smaller grain size, and larger coating thickness compared to Ni/WC coatings. Doping of MoS2 promoted the deposition of WC, further enhancing the microhardness of the coatings. The Ni/WC-MoS2 composite coatings doped with 5 g/L MoS2 exhibited a maximal microhardness of 730 HV0.1 and minimized the coefficients of friction (CoFs) to 0.3. The wear mechanism of the coatings transformed adhesive wear into oxidative wear assisted by abrasive wear, improving the abrasion resistance and reducing the wear rate. The wear rate of the Ni/WC-5 g/L MoS2 composite coating decreased by 47.34% compared to coatings without MoS2 doping. Doping MoS2 effectively enhanced the surface wear resistance.

Summary: In this study, WC-Cr3C2-Ni and WC-Ni coatings were applied to steel surfaces using HVOF spray. The corrosion behaviors of these coatings in 3.5 wt% NaCl solution with varying Na2S concentrations were investigated. Electrochemical tests were conducted to measure the corrosion resistances of the coatings, while SEM and XPS analysis were used to study their morphologies and corrosion products. It was found that the passivation of the coatings played a key role in their corrosion resistances, with sulphide concentration negatively affecting the integrity of passive films. The WC-Cr3C2-Ni coating exhibited better corrosion resistance due to its stable structure and higher tendency for repassivation.

Summary: Metal matrix composites reinforced with WC particles and Co or Ni matrices are known for their unique combination of hardness, toughness, and superior wear performance. This study focused on Ni-WCNi composite coatings and found that coatings with higher WC fill ratios displayed better wear resistance due to the uniform distribution of WC particles and shorter mean free path reducing adhesive wear. However, at higher loads, subsurface crack propagation at WC particle interfaces led to a reduction in the protective role of mechanically mixed layers. Scratch tests were used to qualitatively compare coating cohesion strengths and correlate them to wear properties.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.
