Abstract

U ovom radu dan je teorijski pregled stanja tehnike senzora atmosferske korozije. Atmosferska korozija bitan je problem industrijskog i infrastrukturnog inženjerstva pa su osmišljene brojne tehnike i senzori za njeno sprječavanje. Približna procjena atmosferske korozijske brzine može se napraviti uz pomoć normi ISO 9223 : 2012 i ISO 12944 – 2, a senzori omogućuju njezino izravno mjerenje. U radu su opisani primjeri senzora koji koriste elektrokemijske metode mjerenja brzine korozije. Opisane su tri različite vrste senzora na principu elektrokemijske impedancijske spektroskopije kojima je ispitivana atmosferska korozija pod različitim uvjetima vlage, atmosferska korozija u morskim uvjetima i brzina korozije metala pod tankim filmom elektrolita. Opisan je Fe-Ag tip senzora za praćenje brzine korozije u automobilskoj industriji koji radi na galvanskom principu. Senzori i tehnike praćenja korozije stalno se unaprjeđuju pa je tako u ovom radu opisan novi elektrokemijski senzor povezan s tehnikom elektrokemijskog šuma.

Abstract (english)

In this thesis a review of the state-of-the-art of the atmospheric corrosion sensor techniques has been given. Atmospheric corrosion is an important issue of industrial and infrastructure engineering therefore many techniques and sensors have been developed for its prevention. Approximate corrosion rate estimation can be made using standards ISO 9223: 2012 and ISO 12944-2 but sensors enable its direct measurement. This thesis describes atmospheric sensors based on electrochemical techniques. Three different sensors, based on electrochemical impedance spectroscopy, for monitoring atmospheric corrosion under various humidity conditions, marine atmospheric corrosion and the corrosion rate of metal under a thin electrolyte film, have been described. Fe-Ag sensor for use in automotive industry, based on galvanic principle, is presented. Corrosion monitoring sensors and techniques are constantly being improved so that a new electrochemical sensor related to electrochemical noise has also been described in this thesis.
