【Abstract】 The law of corroding effect of trona components on welding points of steels has been studied by way of simulating caustic trona liquid with various concentrations and making corrosiveness tests in both static and dynamic states for different lengths of time and at different temperatures.The transmission electron microscope has been used to observe and analyze the contour forms and products of welding points so as to reveal their corrosion mechanism.更多还原
