Intermetallic compounds with special physical and chemical properties are considered to be advanced materials. However, the brittleness at room temperature of intermetallic compounds leads to poor performance, which limits its widespread application in engineering. The objective of this study is to investigate the strengthening mechanism of the copper (Cu) on the microstructure and material performance of WC/NiAl/TiC composite coatings by the laser cladding process. The results reveale that Cu element has a significant effect on the microstructure evolution of the coatings by inhibiting coarse crystal formation. The refined microstructure of the layer had been realized. X‐ray diffraction (XRD) analysis demonstrate a reduction in lattice spacing within the composite coating structure as the proper Cu is added. Furthermore, the addition of Cu contributed to an enhancement in microhardness (868.9 HV0.2) and wear resistance. With 3% copper been added, the wear loss of the coatings has been reduced by 81.13% and the average microhardness value has been increased by 1.4 times as well. Moreover, the chemical metallurgical bond is produced between the particles and bonding phase resulting in strengthened compactness within the layer acting as a physical barrier‐like film that increases polarization resistance.

Ni60-WC coatings with different WC contents on the bucket tooth substrates were pre- pared using laser cladding technology. Their abrasive wear properties were assessed using the dry sand rubber wheel test system. The substrate and the hard-facing layer were tested for comparison. The results showed that the hardness of the Ni60-WC coatings increased with the increase in WC content. The wear resistance of the bucket tooth substrate was greatly improved by hard-facing and laser cladding Ni60-WC coatings. The wear rate of the hard-facing layer was reduced to 1/6 of that of the tooth substrate. The wear rate of the laser cladding coatings with 20–40 wt.% WC was similar to that of the hard-facing layer. It is worth mentioning that the wear rate of the coatings with 60–80 wt.% WC was only 1/4 of that of the hard-facing layer. Micro-cutting with surface plastic deformation was the main wear mechanism of the substrate to form narrow and deep furrows. The wear mechanism of the hard-facing layer was mainly plastic deformation with a wide groove, and the surface cracks promoted the removal of the material. The removal of the binder phase caused by micro-cutting was the main wear mechanism of the laser cladding Ni60-WC coatings. However, the hard phase of WC hinders micro-cutting and plastic deformation, which improves the wear resistance of the coating.

[19,20] As a common failing of superhydrophobic surfaces, poor mechanical durability caused by consumable chemicals and fragile textures is a main engineering challenge that needs to be solved desiderately.

The development of materials that repel water, known as superhydrophobic materials, has been hindered by their vulnerability to mechanical abrasion. This issue is particularly pronounced for superhydrophobic nanocomposite coatings fabricated using a simple blend of resin and nanoparticles through uncomplicated methods such as spraying or brushing, where an excessive amount of nanoparticles can deteriorate the mechanical property. Moreover, the limitation of thickness put forward a request of a high retention rate of the coatings. In response to these challenges, this study presents an innovative approach aimed at enhancing the robustness of superhydrophobic nanocomposite coatings through the utilization of a straightforward dual spraying technique. The results demonstrated that the particles with hierarchical micro/nanostructures fabricated by the primary spraying process provided abundant roughness feedstocks for the secondary‐sprayed coatings, in which superhydrophobicity properties could be achieved with less nanoparticle content. Additionally, the mechanical durability of the coatings can be reinforced by the addition of appropriate amounts of aluminum oxide (Al2O3) nanoparticles and the continuous‐distributed particles fabricated by the primary‐spraying process, exhibiting a longer abrasion distance and a higher retention rate. Also, the prepared sample shows comprehensive robustness in adhesion, abrasion and dynamic impact tests. By offering insights into material selection and process optimization, this study paves the way for creating resilient superhydrophobic coatings using a streamlined and convenient approach.This article is protected by copyright.
