| titleOfInvention | A kind of corrosion resistant alloy macrostructure and defect show acid etching method |
| abstract | The present invention relates to a kind of corrosion resistant alloy macrostructures and defect to show acid etching method, it includes the following steps: that I cuts corrosion resistant alloy sample, specimen surface to be seen of polishing, and the roughness Ra on surface is not more than 1.6 μm；II sample is put into electric heater unit；III is added technical hydrochloric acid in electric heater unit, and technical hydrochloric acid liquid level is more than specimen surface 50mm to be seen；IV 85 DEG C of electric heater unit set temperature -90 DEG C, electrified regulation；V technical hydrochloric acid reaches 85 DEG C -90 DEG C, and keeps the temperature；VI takes out sample, bleeds off 0.5 ± 0.05 hydrochloric acid of volume, is put into sample；VII adds new technical hydrochloric acid, and technical hydrochloric acid liquid level is more than specimen surface 50mm to be seen；85 DEG C -90 DEG C of the heating temperature of VIII electric heater unit；Ⅸ heat preservation 90 ± 5 minutes；Acid solution in Ⅹ discharge electric heater unit, takes out sample.This corrosion resistant alloy macrostructure and defect show acid etching method, keep showing for corrosion resistant alloy macrostructure and defect clear. |
