چکیده مقاله
In this research, the effect of explosive welding variables on the behavior and corrosion properties of dissilar joining of copper to St52 steel in NaCl environment was investigated The explosive welding process was carried out with different combinations of explosive materials that lead to different collision velocities For this purpose, samples A, B and C were welded with explosives of 80% ANFO 20% TNT, 90% ANFO 10% TNT, and 95% ANFO 5% TNT, respectively Examination of the bonding surfaces was carried out with the help of optical and scanning electron microscopes The results showed that with the increase of the explosive with higher explosive velocity TNT , the interface changed from a smooth state to a wavy state Moreover, the microhardness measurement results showed that the hardness of the samples around the interface increased with the increase of the high explosive substance Examining the results of electrochemical impedance spectroscopy, it was found that with the corrugation of the joint interface, the value of n non uniformity coefficient of the surface decreased so that the highest corrosion was recorded in the sample with the combination of 80% Anfo 20% TNT The results of toefl polarization curves showed that the lowest corrosion rate was related to the sample with the explosive charge combination of 95% ANFO 5% TNT and the highest corrosion rate was related to the sample with the explosive charge combination of 80% ANFO 20% TNT
