2.3 铝及铝合金的吸气和氧化铝及铝合金具有强烈吸气和容易氧化的特点,这是由金属铝的本性决定的.防止铝及其合金的吸气和氧化,涉及方面广且比较复杂.2.3.1 铝及铝合金的吸气根据实际测定结果,铝及铝合金中所吸收的气体主要是氢,约占75～90%,其余气体占10～25%、所谓其他气体,是指N_2、CH_4、CO、CO_2等.由于铝及其合金中所吸收的气体主要是氢,所以有关吸气的研究,实际上就是对吸氢的研究.
2.3 Inhalation of aluminum and aluminum alloy and aluminum oxide and aluminum alloy with a strong inspiratory and easy oxidation, which is determined by the nature of aluminum. To prevent the absorption and oxidation of aluminum and its alloys, involving a wide range and comparison Complex .2.3.1 Inhalation of aluminum and aluminum alloy According to the actual measurement results, the absorption of aluminum and aluminum alloy gas is mainly hydrogen, accounting for about 75 to 90%, the remaining gas accounted for 10 to 25%, the so-called other gases, is Refers to N_2, CH_4, CO, CO_2, etc. Since the gas absorbed in aluminum and its alloys is mainly hydrogen, the study on gettering is actually the study of hydrogen absorption.
