吉峰陶磁器
主な利点
Extreme environmental resistance: Long-term working temperature 1300°C; thermal shock resistance ΔT ≥ 800°C.
Ultra-high strength & 靭性: Bending strength ≥ 800 MPa; fracture toughness 6–8 MPa·m¹ᐟ², better impact resistance than zirconia.
Self-lubricating & wear-resistant: Friction coefficient ≤ 0.15 (dry); hardness HV10 1400–1600; service life >10× metal parts.
Lightweight & energy-saving: 密度 3.2 g/cm3; 60% lighter than steel, reducing inertia and energy consumption.
