A METHOD TO TRACE CATHODIC SECOND-PHASE PARTICLES AT MG ALLOY SURFACE AND A METHOD TO MANUFACTURE USING THE METHOD TO TRACE

摘要

According to the present invention, a method for detecting a second-phase particle on a surface of a magnesium alloy comprises: a first step for preparing a magnesium alloy sample; a second step for depositing the magnesium alloy sample for a certain period of time in a container stored with an alkaline solution; and a third step for confirming presence of a second-phase particle from the surface of the magnesium alloy sample deposited in the alkaline solution, and confirming presence of the second-phase particle in the third step with a bubble generated from the surface of the magnesium alloy sample. In addition, the present invention is configured to process a surface of a magnesium alloy as removing the second-phase particle detected through brushing, etching or polishing methods, after detecting the second-phase particle present on the surface of the magnesium alloy sample using a method of detecting a second-phase particle on a surface of a magnesium alloy.
