Abstract

The invention discloses high-resistance electrothermal alloy which is subjected to passivation treatment. Passivation treatment comprises the following steps that (1) 1-2 parts by weight of organic amine alkali, 1.5 parts by weight of barium metaborate, 1.1 parts by weight of boric anhydride, 0.7 part by weight of sodium bromite and 1.6 parts by weight of ethylene glycol monostearate are sequentially put into 25 parts by weight of deionized water and uniformly stirred; (2) 1.2 parts by weight of dioscorea cirrhosa lour residue extractive, 0.8 part by weight of sodium hexametaphosphate, 1.2 parts by weight of sec-alkyl sodium sulfate, 2.3 parts by weight of carbamide and 1.7 parts by weight of benzotriazole are added into the mixture obtained in the step (1), and stirring continues till theadded components are uniformly mixed, and passivation treating fluid is obtained; and (3) the high-resistance electrothermal alloy is put in the passivation treating fluid to be subjected to passivation treatment at the temperature of 50 DEG C for 30 s, and then the high-resistance electrothermal alloy is taken out, cleaned with pure water and dried. The high-resistance electrothermal alloy is good in performance and surface smoothness after being subjected to passivation treatment.

Description
