2 A method to trace cathodic second-phase particles at Mg alloy surface and A method to manufacture using the method to trace

摘要

A two-phase particle detection method of a magnesium alloy surface according to the present invention includes a first step of preparing a magnesium alloy sample, a second step of immersing the magnesium alloy sample in a vessel containing the alkaline aqueous solution for a predetermined time, And a third step of confirming the presence or absence of two-phase particles from the surface of the magnesium alloy sample. In the third step, whether or not the two-phase particle is present is determined from the surface of the magnesium alloy sample, . The present invention also relates to a method for detecting two-phase particles present on the surface of a magnesium alloy sample using a two-phase particle detection method on the surface of a magnesium alloy, and then removing the two-phase particles detected through brushing, And the surface of the magnesium alloy is processed.
