Metal oxide etch usually happens on the thermal hydrodynamic test rig when its equipment, pipelines and valves are made of carbon steel. 在由碳钢制造的设备、管道和阀门等部件所组成的热工水力试验台架中,金属的氧化腐蚀是一个普遍存在的问题。
Because the role of oxide etch is aggravated by elevating temperature, the deforming resistance of titanium alloy falls down and creep occurs and the fatigue property of materials is worsening. 温度升高加剧了环境的氧化和腐蚀作用,出现高温塑性变形机制(如蠕变),并引起钛合金的变形抗力的下降,造成材料本身的疲劳性能恶化。
