Abstract:
     The present invention uses benzotrichloroazole (BTA) as corrosion inhibitor for iron-ware cultural relic and has obtained unexpected result. The experiment verified that the lower concentrated BTA has higher efficacy of corrosion inhibition and does not change the color of iron ware as tannic acid does which is the popular corrosion inhibitor used at present. Besides, it also has the advantages of low toxicity and low cost.
