Apstrakt

Otpornost na koroziju mekog čelika, koji se koristi za izradu ploča trupa u brodskoj tehnologiji, u morskoj vodi pre nanošenja boje [Nippon boja SUMO KSTRA izdržljivi spoljašnji emulzioni premaz (emulzioni premaz)] i nakon nanošenja boje je izmerena elektrohemijskim studijama kao što je studija polarizacije i spektri impedanse naizmenične struje. Primećeno je da se nakon nanošenja boje povećava otpornost na koroziju ploča trupa od mekog čelika. Studija polarizacije otkriva da se nakon nanošenja boje raste otpor linearne polarizacije i smanjuje struja korozije. Spektri impedanse naizmenične struje otkrivaju da se u prisustvu bojenog premaza vrednost otpora prenosa naelektrisanja povećava, vrednost impedanse povećava, fazni ugao raste i vrednost dvoslojnog kapacitivnosti opada. Efikasnost inhibicije korozije bila je veća od 99%. Ploče trupa od mekog čelika mogu biti premazane izdržljivim spoljašnjim emulzionim premazom (emulzioni premaz). Ovo će kontrolisati koroziju ploča trupa u morskoj vodi. Doći će do povećanja veka trajanja ploča trupa.
