“…Tsunekawa prepared a cast iron coating with a friction coefficient of only 0.1~0.11 on the aluminum alloy substrate [6,7]. This paper mainly studied the organic polymer-bearing bush coating with aluminum particles as the reinforcing phase, analyzed the experimental factors in the preparation process of the coating, and studied the effects of different curing temperatures, preheating temperatures, spraying thicknesses, and curing times on the adhesion and bonding strength of the coating [8][9][10]. The oxidation mechanism, wear resistance, and wear reduction behavior of aluminum particles were studied by orthogonal analysis of the prepared samples, and the optimum preparation conditions of the coating were determined.…”

In view of the upgrading of engine-bearing pad-coating materials, the preparation of functional coatings suitable for bearing pad surfaces sprayed with aluminum particles as the reinforcing phase has important application value. In this paper, the exploration of preparing composite coatings on the working surface of bearing pads with aluminum particles as the reinforcing phase was carried out through orthogonal experiments. The effects of different process parameters on the adhesion, bonding strength, and micro-hardness of the coatings during the preparation process were studied, which provided a theoretical basis for the preparation of functional coatings.

“…In recent years, transitionmetal diborides (TMB 2 ), such as TiB 2 , CrB 2 , and WB 2 , have attracted growing attention for hard coatings because of their excellent properties [1,2,3,4,5]. In the TMB 2 systems, AlB 2 -type WB 2 coating has widely followed with interest due to its high hardness (35)(36)(37)(38)(39)(40)(41)(42)(43)(44)(45), high melting point (2560 °C), and good wear resistance, which makes it an excellent candidate as a protective coating [6,7,8,9,10,11,12]. However, the low toughness of AlB 2 -type WB 2 coating and the poor adhesive strength induced by the huge difference in the hardness and thermal expansion coefficient between the coating and substrate, such as cemented carbide, limit its further application in industry.…”

Amorphous WB 2 /Ti multilayer coatings with different modulation ratios (1, 5, 15, and 30) and different bilayer numbers (10, 20, 30, 50, and 70) were deposited by direct-current magnetron sputtering. The effect of modulation ratio and bilayer number on the microstructure, mechanical, and tribological properties of WB 2 /Ti multilayer coatings was studied systematically. In the investigation for the influence of modulation ratio, the hardness of the multilayer coatings increases with the increment of modulation ratio. The indentation toughness shows a different changing tendency compared to that of the hardness with different modulation ratios. The wear rates of the multilayer coatings with different modulation ratios are at the same level with the influence of both hardness and indentation toughness. In the investigation for the influence of bilayer number, both hardness and indentation toughness increase first and then decrease with an increasing bilayer number. WB 2 /Ti multilayer coating with a modulation ratio of 5 and bilayer number of 50 exhibits the highest hardness of 20.4 GPa and lowest wear rate of 1.76 × 10 −16 m 3 /Nm. In addition, the hardness strengthening mechanism and wear mechanism of the multilayer coatings were discussed in detail.

“…As one of ultra-incompressibility 5d transition metals, tungsten is characterized by the existence of directional metallic bonds which results in the potential to be superhard materials for tungsten diborides [6][7][8]. Besides the excellent material availability of W, the most widely investigated AlB 2 -type WB 2 films possess high hardness, low friction coefficient and good chemical inertness that could play an important role in protective, wear resistance films and diffusion barriers [9][10][11][12][13][14][15]. Magnetron sputtering is one of the most effective methods to fabricate the metastable AlB 2 -type WB 2 films at relatively low temperature.…”

The influence of the bilayer number on the microstructure, mechanical properties, adhesion strength and tribological behaviors of the WB 2 /Cr multilayer films was systematically investigated in the present study. Five groups of WB 2 /Cr films with the same modulation ratio were synthesized by magnetron sputtering technique. The crystalline structure of the films was determined by X-ray diffraction. The morphologies and the microstructure of the films were observed by scanning electron microscopy, atomic force microscopy and transmission electron microscopy. Furthermore, Nano indenter, scratch tester and ball-on-disc tribometer were used to evaluate the mechanical and tribological properties. As bilayer numbers varied from 5 to 40, the hardness increased first and then decreased with the maximum hardness of 33.9 GPa when the bilayer number is 30. The H/E * and H 3 /E *2 values calculated to evaluate the fracture toughness showed the similar changing trend with hardness. The adhesion strength reached the maximum of 67 N when the bilayer number is 30. The surface roughness and friction coefficient decreased with increasing bilayer number. The wear mechanism was also investigated, and the results suggested that the multilayer film with bilayer number of 30 exhibited the best wear resistance (1.78 × 10 -7 mm 3 /Nm), benefiting from the contribution of high hardness, fracture toughness and adhesion strength.
