“…With investigations about the influence of different surface morphologies on friction performance, significant decrease in COF and wear ratio has been found in the textured sample compared with smooth sample, especially in starved hydrodynamic lubrication [209][210][211][212][213][214]. The comparison of the variations in the friction coefficient among the three types of discs at different sliding speeds was shown in Fig.…”

To improve the tribological characteristics of the face seal, the squamous groove micro textures with different area proportion and the circular dimple micro texture were designed and manufactured. The disc-disc friction and wear experiments and numerical simulation were carried out in oil lubrication. The pressure distribution, friction coefficient, fluid temperature and wear morphology are investigated. The study show that the friction coefficients of the micro textured and untextured samples decline with the increase of load, but first increase and then decrease with the rise of rotational speed. Micro textured samples could decline the friction coefficient effectively, and the asymmetric structure in the lubricant inflow and outflow region of the squamous groove micro texture makes it have better tribological performance. In addition, the micro texture can increase heat dissipation area, reduce heat production and collect wear debris, which could modify the lubricant temperature and wear morphology effectively.

“…As for the groove, not many grooves shape was investigated. Most studies done were on the line groove [22][23][24][25][26][27][28] and some on grid [24,26,27,29,30], wavy [31] and sinusoidal [12,32] groove. In a study by Wang et al, circle dimple presented the best friction reduction and line groove help to stabilize friction [33].…”

The purpose of this paper is to investigate the effect of multi-shape photochemical textured (PCT) steel surfaces on tribological performance. The textured surface with specific arrangement was fabricated by photochemical texturing, a common technique implemented in the microelectronic mechanical systems (MEMS) industry. It involves photolithography and chemical etching processes. The multi-shape studied were circle with line (CL) and circle with wavy (CW). Fabricated samples’ surfaces were characterized by using a 3D optical profiler to check the produced texture’s dimension. The effect of six different etching times on the texture’s dimension was observed. Then, only two sizes of both multi-shape textures were considered for tribological characterization. It was conducted by using ball-on-disk tribo-tester under lubricated conditions. The results obtained are compared with the reference untextured (UT) surface. From the results, it is found that appropriate size and shape of texture could lead to good friction reduction and anti-wear behaviour. The smaller size, size A, of CL multi-shape presented a lower friction coefficient compared to size B. However, different size of CW multi-shape has no effect on the friction behaviour. This is believed due to higher area density of CW compared to CL resulting in detrimental effect on friction for both CW’s size. Additionally, CL(size A) textured surface shows improved tribological behaviour compared to UT surface as lower friction coefficient and better wear resistance is obtained. This is maybe due to effective lubricating layer formation, good debris trapping effect and lower contact stress of the CL(size A) textured surface. These beneficial effects were achieved under lubricating condition through an increase in applied load.
