| Zusammenfassung: | The invention relates to the technical field of metallographic structure analysis of high-temperature alloys, and specifically discloses an electrochemical corrosive agent showing intergranular precipitated phases of SLM forming IN 718 nickel-based high-temperature alloys. The electrochemical corrosive agent is composed of an oxide film electrolytic corrosive agent, a metallographic electrolytic corrosive agent and a surface cleaning agent, wherein the oxide film electrolytic corrosive agent is prepared from the following components in fraction by volume: 20-30ml of perchloric acid, 60-75ml ofethanol absolute and 5-10ml of glycerol, the metallographic electrolytic corrosive agent is prepared from the following components in fraction by volume: 10-20ml of perchloric acid and 80-90ml of ethanol absolute, and the surface cleaning agent is prepared from the following components in fraction by volume: 30-40ml of an ethanol absolute solution and 30-40ml of deionized water. The electrochemical corrosive agent is eas |
