description The invention discloses a test system and test method for accelerating metal corrosion by feeding oxygen gas under dry and wet conditions. The test system includes an oxygen gas feeding device, an oxygen gas feeding control device, a corrosion container, an exhaust control device and a corrosive liquid feeding device. The oxygen gas feeding device is connected to the oxygen gas feeding control device by means of a sealing member; the oxygen gas feeding control device is connected to the corrosion container by means of a sealing elbow; the corrosion container is connected to the exhaust control device by means of a sealing member and is connected to the corrosive liquid feeding device by means of a sealing elbow; a pressure reducing valve can control output pressure of gas by means of an adjusting knob, so as to ensure that oxygen gas in an oxygen gas bottle can be stably output; and a timing power supply controller has a setting function of timing power-on and power-off. The invention can be used for studying a corrosion rule of a metal in an alternating dry and wet corrosion environment under a condition of fully considering oxygen, so as to evaluate corrosion resistance of the metal.
