Kev tsis

High-precision cov pob ceramic yog spherical cov khoom siv ua los ntawm zirconium oxide (sitostatic) los yog al₂o₃) los yog aluminium oxinging ({0 -199 0 degree) thiab ultra-precision sib tsoo cov txheej txheem. Silicon nitride cov khoom pob muaj cov zoo dua ntawm 3.20-3,30 G /MACE HARDENCE 6-16 Qhov chaw saum npoo av ra tsawg dua lossis sib npaug rau 0.01 μm, lub sphererity yuam kev tsawg dua los yog sib npaug ntawm qhov kub thiab txias (}} lossis sib npaug rau 3.2 × 10⁻⁶ / degree). Pob zeb diamond sib tsoo log yog siv nyob rau hauv cov qhabnias rau ntau hom machis-tshuab. Txuas sib tsoo thiab sib nqus cov kua hlau polishing tshuab 36], tawg, pits, pits thiab snowflake tsis meej (qhov xwm txheej<0.01%), combined with ultrasonic C-scan non-destructive testing with a resolution of 10μm to ensure a sub-surface crack detection rate of ≥99.9%; in high-speed bearing applications, the friction coefficient is as low as 0.001–0.005, the maximum speed reaches 3×10⁶dN value (d is the aperture mm, N is rpm), and the service life is increased by 5–8 times compared with steel balls. The global market size is expected to reach US$1.27 billion in 2025, mainly used in semiconductor wafer polishing (particle size 0.1–3mm tolerance ±0.05μm), aircraft engine spindle bearings (DN value ≥2.5×10⁶) and new energy vehicle electric drive systems (anti-electrolytic corrosion grade Class 5).
