Adaptation and self-healing effect of tribo-oxidizing in high-speed sliding friction on ZrB2-SiС ceramic composite

Self-Lubricating Effect of WC/Y–TZP–Al2O3 Hybrid Ceramic–Matrix Composites with Dispersed Hadfield Steel Particles during High-Speed Sliding against an HSS Disk

“…High-speed (high-temperature) sliding is gaining more and more interest in tribology in connection with studying tribological characteristics and behavior of new composite materials, especially if prospecting for those capable of demonstrating adaptation mechanisms [1][2][3][4][5][6][7][8][9]. These adaptation mechanisms are usually related to the generation of anti-friction or/and anti-wear films on the worn surfaces from the components of materials used in the tribological testing as well as active environmental elements such as oxygen [1][2][3][4][5][6][7][8][9].…”

The first stage of such an adaptation mechanism can be intense deformation or grain refining, generation of wear debris, adhesive transfer, and high-temperature tribo-oxidation of them with the mechanochemical formation of low-friction and self-lubricating products such as solid or liquid mixed oxides, etc.…”

“…High-speed sliding usually means unlubricated sliding at speeds in the range of 5-90 m/s and only a limited number of materials can be capable of sustaining that harsh condition [7][8][9][10][11][12][13][14][15][16][17][18][19]. Those may be hybrid sliding pairs with ceramics, ceramic matrix (CMCs), or metallic matrix (MMCs) composites rubbed against hardened alloyed steel counterbodies [7][8][9][10][11][12][13][14][15][16][17][18][19]. It is worthwhile noting that despite temperatures as high as 1500-3000 • C that the melted Hadfield steel.…”

Analysis of surface structure of zirconia crystals in case of friction against steel

“…Much attention is paid to the study of the nature of friction of zirconium ceramics. In paper [1], the high-speed friction of zirconium ceramics against high-carbon steel was studied. The friction surfaces were studied in terms of chemical composition and mechanical properties.…”
