“…Electro brush-plating, also known as selective plating or swab coating, is considered a very useful and portable surface modification method for gear steels [14]. Brush-plating has been successfully applied to the preparation of single or multiple phase coatings on materials due to its easy-to-adjust coating thickness and good deposition quality [15][16][17][18]. The coatings deposited by brush-plating have excellent wear resistance, corrosion resistance, and high hardness [19][20][21].…”

Cr-coating was deposited on AISI 5140 steel by electro brush-plating, followed by annealing treatment at different temperatures, from 300 to 1100 • C. The microstructure evolution of the Cr-coating was characterized by backscattered electron imaging (BSEI) and energy dispersive spectrometry (EDS). The results show that the brush-plated sample has a nodular shaped microstructure, which is very stable at 300 • C of annealing. At 500 • C of annealing, the constitution of the microstructure changes from nodules to grains. As the annealing temperature further increases, the grains grow significantly. When the temperature reaches 1100 • C, a Cr-Fe solid-solution layer is formed within the original pure Cr-coatings. With increasing annealing temperature, the number of micro-cracks in the coating increases first and then decreases, reaching a maximum at 500 • C. The hardness and wear-resistance of the coating are improved when the annealing temperature increases to 1100 • C, owing to the decrease of micro-cracks that formed during brush-plating.

“…The coating deposited by brush-plating has unique corrosion resistance, abrasion resistance and hardness advantages [21][22][23]. The brush-plating has been applied in many fields such as the study of superhydrophobic surfaces [24,25]. It has been pointed out that like electroless or electroplated palladium films, it is possible to deposit stainless steel palladium films with good corrosion resistance and adhesion strength by brush-plating [26].…”

Cr-Fe2B composite coatings were prepared on carbon steels by pack-boronizing followed by electro brush-plating. The microstructure and properties of the coatings annealed at different temperatures were studied. The coatings show a gradient structure composed of a Cr-layer and a Fe2B-layer and have excellent thermal stability, and no new layers and/or transition layers are formed in the coating during annealing up to 1000 °C. The Cr-layer has an amorphous structure and is transformed into nanosized grains when the annealing temperature increases to 700 °C. As the annealing temperature is further increased, the nanograins grow rapidly. The microcracks in the Cr-layer increase sharply after annealing at 550 °C and then decrease significantly with any further increase of the annealing temperature. The pre-deposited Fe2B-layer prevents the formation of carbon-poor zones in the steel substrate during annealing. It is considered that high-temperature (>700 °C) annealing helps to eliminate coating defects, increase the coating density and obtain better wear resistance and corrosion resistance. Surprisingly, the as-plated and low temperature annealed samples also show good wear resistance and corrosion resistance, which may be related to their amorphous structure and nanocrystalline structure.

“…In order to improve the hardness and wear resistance of superhydrophobic surfaces, a composite electrodeposition method has been developed in the current literature [ 18 ]. Many particles with different properties can be employed in this approach, resulting in the enhancement of abrasion resistance, tribology, and corrosion resistance.…”

Fabrication of a Low Adhesive Superhydrophobic Surface on Ti6Al4V Alloys Using TiO2/Ni Composite Electrodeposition

et al. 2019

A superhydrophobic surface with low adhesion and good wear resistance was fabricated on Ti6Al4V substrates via TiO2/Ni composite electrodeposition, and subsequently modified with a fluoroalkylsilane (FAS) film. Scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and optical contact angle measurements were used to characterize the surface morphologies, chemical compositions, and surface wettability. The superhydrophobicity of the as-prepared surface results from the fabrication of a hierarchical structure and the assembly of low-surface energy fluorinated components. The as-prepared surface had a water contact angle as high as 162.6° and a sliding angle close to 1.8°. Scratch and abrasion tests showed that the superhydrophobic coating provided a superior wear resistance and stable mechanical abrasion protection. In addition, the influence of processing conditions, such as working voltage, deposited time, pH value, and TiO2 concentration, was also investigated.
