研制了一种适合于铀及合金大气腐蚀加速试验的流动气体氧化研究仪。该仪器能满足高温湿空气试验(105℃,10％R.H.,空气),湿N_2试验(70℃,95％R.H.,N_2)大气腐蚀加速试验条件,也可作常规的湿热试验(按美国军事标准Mil-Std-810C-507:70℃,95％R.H.,空气),试验时空气或N_2气的流量在0～1L/min之间可以调节,当进行湿N_2试验时气氛中的氧含量可保持低于4ppm。当进行高、低温湿空气试验时,可用热天平在试验过程中直接测量试样重量。 Developed a suitable for uranium and alloy atmospheric corrosion accelerated test instrument of mobile gas oxidation. The instrument can meet the atmospheric corrosion accelerated test conditions of high temperature and humidity air test (105 ℃, 10% RH, air) and wet N_2 test (70 ℃, 95% RH, N_2), and can also be used for conventional damp heat test Mil-Std-810C-507: 70 ° C, 95% RH, air). The air or N 2 gas flow rate can be adjusted between 0 and 1 L / min. The oxygen content in the atmosphere can be maintained when the wet N 2 test Below 4ppm. When high and low temperature wet air test, the thermobalance can be used directly in the test process to measure the weight of the sample.
