- Abstract
High concentration hydrogen peroxide(H\small 2O\small 2) has characteristics of heavy density, high specific impulse, storable and non-toxic, the compatibility of H\small 2O\small 2 is an important index in hydrogen peroxide propellant tanks design. Aluminium alloy contained scandium possesses high strength, plasticity and very good welding property, corrosion resistance property and so on. The compatibility of medium strength 5B70 aluminium alloy contained Scandium with 90\% H2O2 was investigated. The results show active oxygen loss ratio of H\small 2O\small 2 with 5B70 alloy is less than 5\%, strength loss less than 5\%, pitting corrosion is the typical characteristic of the 5B70 alloy. The 5B70 alloy is an ideal performance high concentration H\small 2O\small 2 tank’s material.
