Apparatus and method for accelerating gas infiltration into materials

A method for accelerating gas infiltration into materials, comprising the following steps:

• placement of to-be-tested material:
• placing a to-be-tested material in a reaction unit, and locking the reaction unit;
• introduction of inert gas and confirmation for leakage:
• continuously inputting an inert gas into the reaction unit while controlling a flow rate of the inert gas by a first pressure regulator until the reaction unit is filled with the inert gas, repeatedly introducing and discharging the inert gas to remove the original gas in the reaction unit, and detecting whether there is gas leakage in the reaction unit;
• if there is leakage, confirming a position of the inert gas leakage in the reaction unit, and relocking the reaction unit;
• discharge of inert gas and introduction of hydrogen:
• if there is no inert gas leakage, discharging the inert gas out of the reaction unit by an exhaust system, and introducing the hydrogen into the reaction unit;
• heating and pressurization:
• setting a temperature and inputting heat energy by a heater, and pressurizing the hydrogen and inputting the hydrogen to the reaction unit by a pressurization unit;
• infiltration of to-be-tested material:
• enabling the hydrogen to infiltrate into the to-be-tested material at a controlled temperature and a controlled pressure;
• discharge of gas mixture:
• discharging the hydrogen out of the reaction unit, inputting the inert gas by the storage unit, mixing the hydrogen and the inert gas to form a gas mixture, and discharging the gas mixture out of the exhaust system by the exhaust system;
• and
• removal of to-be-tested material:
• removing the to-be-tested material from the reaction unit after the temperature and the pressure drop to normal values.
