  • Patent number: 12473211
    Abstract: A method of decomposing a fluidic product (110) having a plurality of particles (112) is disclosed. The method includes inductively heating the fluidic product (110) at a first predetermined temperature while flowing through a temperature rising portion (138) having a first heating region formed of at least one metal pipe (124) by using a first heating induction coil (134) surrounding the first heating region; holding a temperature of the fluidic product (110) at approximately the first predetermined temperature for a predetermined reaction period while flowing through a temperature holding portion (140) having a second heating region formed of at least one metal pipe (124) by inductively heating the temperature holding portion (140) using a second heating induction coil (136) surrounding the second heating region; and decomposing the fluidic product (110) while flowing through the temperature rising portion (138) and the temperature holding portion (140) during the predetermined reaction period.

  • Patent number: 12404576
    Abstract: A method of fusing an alloy-based material with a coating layer using a thermal spray process. The method includes determining a predetermined energization frequency of a high-frequency power supply unit based on a diffused area thickness (T1) and a non-diffused area thickness (T2) of the alloy-based material, inductively heating the alloy-based material and the coating layer to reach a predetermined temperature at the predetermined energization frequency of the high-frequency power supply unit, selectively heating the alloy-based material at the predetermined energization frequency within a penetration depth range of a total thickness (D2) of the alloy-based material to suppress an austenite transformation of at least a portion of the alloy-based material, and fusing the selectively heated alloy-based material with the coating layer by suppressing the austenite transformation of at least the portion of the alloy-based material.
