The influence of heat-input and pre-heat treatment on the structure, mechanical and corrosion behaviors of 2205 duplex stainless steel joint by means of GMAW process was the goal of this study. In this regards, the welding process was done using different heat input in the range of 0.6 to 1.4 kJ/mm and different pre-heating treatments in the range of 25 to 100 oC. The microstructural properties...
According to the statistics of China Electricity Council, about 97% China’s coal-fired power generating units adopted wet desulfurization process (WFGD), which limestone-gypsum is main process, accounting for 91% coal units. Without GGH, chimney exports can form white smoke plume. To solve problem environmental protection plume and boiler flue gas waste heat recovery, exchanger will be applied ...
In this study, the effect of molybdate on the electrochemical behavior and semi-conductive properties of duplex stainless steel 2205 passive film at NaCl solutions was investigated. Cyclic potentiodynamic polarization, impedance spectroscopy, mott-schottky plots and scanning electron microscopy (SEM) were used to study the passive behavior. Polarization curves showed that the corrosion current ...
