Abstract :
In the present study, the effect of thermal treatment on the corrosion behavior and microstructure changes of two-layer stainless-304-Cu sheet steel sheets after the explosive welding process has been investigated. Explosive welding has been done in parallel with an explosive layer of 46 and 63 µm and a stop distance of 2-3 mm. After explosive welding, the heat treatment process was carried out at 350 and 450 ° C for 8 and 16 hours. Explosive welding with an explosive load and variable stop distance. From the results of the electrochemical impedance test, it can be seen that the n number in the heat treatment sample at 350 ° C and 8 hours is less than the heat treatment sample at 450 ° C and 8 hours, and as a result, the corrosion current in the heat treatment sample The temperature is 350 ° C and the time is 8 hours, which reduces the load transfer resistance. By comparing the heat treatment samples at 350 ° C and 8 hours and the heat treatment at 450 ° C and the time of 8 hours with varying aniline temperature, the annealing time is constant and the heat treatment sample at 450 ° C and time 8 The hour with more annealing temperature has a value of n (0.80), followed by heat treatment at 350 ° C and 8 hours (n = 0.66), due to annealing temperature and reduced energy storage In the chapter.
