Tribological investigation of Si3N4-hBN on HXLPE bearing couple: Effects of sliding velocity and contact load

Basic Bio-Tribological Performance of Insulating Si3N4-Based Ceramic as Human Body Replacement Joints

“…In recent years, our team also focused on the bio-tribological properties, and found that addition of hBN significantly reduced the friction coefficient of Si 3 N 4 /TC4 bearing couple under simulated body fluid due to the formation of tribofilm [21]. It was also demonstrated that sliding velocity and contact load have obvious influence on the tribological behaviors of Si 3 N 4 -20%hBN/HXLPE bearing couple under simulated body fluid [22]. However, the influence of hBN content on the bio-tribological performance of Si 3 N 4 /HXLPE bearing couple under simulated body fluid has not been systematically studied.…”

Identification and visualization of cell subgroups in uncompensated flow cytometry data

“…These unique surface characteristics make the silicon nitride antibacterial [16]. Related studies showed that a polished silicon nitride surface promotes cell yield, proliferation of osteoblast cells and greater osteocalcin production [3,17,18]. Among the shaping techniques of ceramics, tape casting enables the production of a surface, which is extremely smooth and flat and may eliminate the necessity of extra polishing step.…”

Investigation of the tribological behaviour of cermets sliding against Si3N4 for seawater hydraulic components applications

“…The results show that the wear rates and friction coefficient were lower during the sliding process and were approximately 10 −7 mm 3 N −1 •m −1 and 0.1<μ<0.2, respectively. Chen et al [17][18][19][20] comparatively investigated the tribological characteristics of Si 3 N 4 -hBN composites sliding against different materials under different lubrication conditions in seawater. The results show that the wear surfaces could be polished and tribopairs entered to the status of liquid lubrication when hBN content was appropriate.…”
