Si3N4 ceramic matrix composites (SN‐CMCs) have been designed and widely used in many engineering fields under externally loading conditions. It is well known that the wear of materials is closely related to components’ mechanical reliability and service life. Understanding of the friction and wear performances is very important to provide insights into how to improve the wear resistance of materials. Coefficient of friction and wear rate, in general, are the most critical parameters of tribological behavior of materials. In this paper, friction and wear performances of SN‐CMCs are reviewed from the perspectives of doped phase, layered structure design, and laser surface texturing. The article describes the change of friction and wear performances of SN‐CMCs sintered with different additive phases. Tribological behavior of SN‐CMCs with engineering designed layered structure is also analyzed from the aspects of surface coating and gradient structure. In addition, friction and wear performances of SN‐CMCs under different lubrication conditions are also discussed. As an ideal processing method for hard and brittle ceramic materials, laser surface texturing has been proved to be an effective way to improve the wear resistance of SN‐CMCs. Researches have shown that the better wear resistance can be obtained by combining laser surface texture with layered structure. At the end of paper, studies on friction and wear performances of SN‐CMCs are summarized and prospected.

“…Currently, the knee joint is deteriorating, and artificial total knee replacement has become the main way to correct deformation and improve joint function 1 . However, artificial joints suffer from severe corrosion and wear in application, so ceramic materials with high hardness, 2 high wear resistance 3 and good biocompatibility 4 are widely used in the field of artificial joints.…”

Discrete element simulation model and cutting tests are conducted to investigate the surface damage during the machining of green ZrO 2 ceramics.The discrete element simulation model (DEM) is developed based on the macroscopic physical and mechanical properties of the isostatically pressed green ZrO 2 ceramics. The validity of the simulation model is verified by cutting tests on green ZrO 2 ceramics. The results show that the physical and mechanical properties of the DEM model established by the PFC2D software are consistent with the macroscopic physical and mechanical properties of the green ZrO 2 ceramics. The depth of cut, the cutting speed, and the tool rake angles have a large effect on surface/subsurface cracks. The tool rear angle has large effect on the distribution of the peak residual stresses. When the cutting force increases suddenly, the number of cracks produced increases sharply. Smaller cutting force can reduce the number of cracks and surface damage.

“…Many research results show that the surface texture of non-smooth units such as pits, bulges, grooves and other microarray structures can effectively reduce friction and resistance [11,12], while at the same time having hydrophobic or superhydrophobic properties [13]. Inspired by the functional surfaces such as lotus leaves, sharks and pitcher plants in nature [14][15][16], the surface texture treatment of titanium alloy can improve its wettability, increase surface contact angle and improve hydrophobicity. Compared with mechanical, laser, electrical/electrochemical discharge machining [17] and other surface texture methods, through-mask electrochemical micromachining (TMEMM) have many advantages, such as no thermal stress and recast layer on the prepared surface and no limitation in the mechanical properties of the workpiece material.…”

TIn order to obtain higher contact angles and improve the hydrophobicity of titanium alloy, the micro pit arrays were fabricated by the through-mask electrochemical micromachining (TMEMM). The theoretical model of surface hydrophobicity between the contact angle and the geometry size of micro pit arrays was developed. Moreover, the multi physical field coupling simulation of TMEMM was carried out. Thus, the direct mapping relationship between the contact angle and the process parameters was obtained by combining the theoretical model with the simulation results. The effect of process prameters, such as electrolyte mass fraction, mask size and processing voltage, was investigated. The optimal combination of process parameters was predicted and verified by experiments. The results show that the errors of the measured values of diameter, spacing, depth and surface contact angle of the micro pit arrays are 2.49%, 6.87%, 7.40% and 6.01% respectively, which indicates that the hydrophobic textured surface with a contact angle of about 141° is successfully fabricated without the modification of low surface energy materials.
