Friction and wear performances of Si3N4 ceramic matrix composites: A review from the perspectives of doped phase, layered structure design, and laser surface texturing

“…38 The friction performance of TC-SN-CMCs is closely dependent on temperature in similar to Si 3 N 4 . [39][40][41][42] Liu et al 43 synthesized TiC 0.3 N 0.7 reinforced TC-SN-CMCs and studied tribological behavior at a broad temperature range. In this study, Ti 3 SiC 2 was added in Si 3 N 4 as a precursor material of TiC x .…”

Intermediate temperature tribological behavior of carbon nanotube reinforced plasma sprayed aluminum oxide coating

“…Tribo-chemical reaction is considered to be an important factor that affects the wear behavior of ceramic materials at elevated temperature [20]. Formation of a smooth thin film or protective layer on the wear surface as result of tribo-chemical reaction can reduce damage to coating surface during sliding [18,20]. The formation of tribochemical layer is explained in Section 3.2.2.…”

“…Further, higher transfer of WO 3 containing film in case of ICP-1 coating is attributed to the higher hardness of ICP-1 coating which leads to more intense wear of WC ball. It is well known that transferred thin film to the wear track acts as a protective layer and can protect the surface effectively against further wear of the coating [18,20]. This phenomenon dominates in the ICP-1 coating which shows the higher area fraction of the transfer film at 873 K and hence least wear (Fig.…”

“…It was observed that, with the increasing temperature, the absorption tendency of moisture on the worn surface decreased and there was no more protective SiO 2 layer resulting in higher wear of the coating. Formation of the protective layer between the ball and the coating occurs due to tribo-chemical reaction which is caused by the moisture/oxygen absorption from the atmosphere [20].…”

Experimental study on the effect of load and rotation speed on dry sliding of silicon nitride

“…Zhang et al (2019) and Llorente et al (2019) studied the tribological behavior of Si 3 N 4 under the condition of graphene addition and found that graphene can attach to the surface of Si 3 N 4 to form a transfer film, which is beneficial to the lubrication and wear reduction of Si 3 N 4 friction pairs. Hibi and Enomoto (1989) studied the friction and wear of Si 3 N 4 in water, n-butanol and their mixtures and found that Si 3 N 4 can be oxidized and esterified in n-butanol to form soluble silicon esters which can reduce friction; Skopp et al (1995) and Kim et al (2001) studied the wear mechanism of Si 3 N 4 from room temperature to 1,000°C and found that only at higher temperatures and higher sliding velocities (above 0.3 m·s −1 at 1,000°C and above 1 m·s −1 at 400°C), a tribo-chemical reaction layer can appear on the wear surface, which lead to significant wear reduction. Zhao et al (2019) tested the tribological characteristics of Si 3 N 4 laser heated to 600°C under dry friction conditions.…”
