对比分析了3种经典公式计算的不同腐蚀周期下LY12CZ铝合金材料疲劳寿命分散系数Lf,研究了Lf随腐蚀周期以及应力的变化规律,并提出了疲劳分散系数的预腐蚀贡献因子的计算公式及与腐蚀影响系数的关系。
The fatigue life dispersion coefficient Lf of LY12CZ aluminum alloy under different corrosion cycles was compared and analyzed by three classical formulas. The variation law of Lf with corrosion cycle and stress was studied and the formula of pre-corrosion contribution factor of fatigue dispersion coefficient Relationship with Corrosion Impact Coefficient.
