Abstract

Zrakoplovi, kao niti ostala tehnička sredstva u čijim se konstrukcijama mahom primjenjuju
metalni materijali, nisu pošteđeni štetnih utjecaja korozije. Korozija se manifestira kroz brojne
pojavne oblike, svaki od kojih predstavlja posebnu vrstu rizika za integritet i uporabljivost
zrakoplovnih konstrukcija. Korozija pogađa gotovo sve dijelove zrakoplova, ponajprije oplatu
i elemente strukture, ali i pogonske uređaje (bili to klipni motori ili plinske turbine) te
elektroopremu i uređaje. U ovome radu prikazani su svi pojavni oblici korozije na zrakoplovnim
konstrukcijama, identificirana kritična mjesta zrakoplova u odnosu na pojavu korozije,
korišteni materijali i njihova suspektnost te su obrađene i metode zaštite od tih štetnih utjecaja.
Osim teoretskog dijela, ovaj rad obuhvaća i praktični (eksperimentalni) dio koji za cilj ima
laboratorijsku analizu komponenti eksploatiranih na protupožarnim zrakoplovima, a na kojima
je došlo do znatnih oštećenja uslijed pojave različitih pojavnih oblika korozije.

Abstract (english)

As with the other technical means involving substantial use of metallic components, aircraft
aren't exempt from many adverse effects imposed by corrosion. Corrosion manifests itself
through various types, each of whom poses a specific risk in terms of structural integrity and
overall aircraft airworthiness. Corrosion impacts all the key areas of an aircraft, primarly its
skin and structure, but it also affects aircraft propulsion (which includes gas turbine engines as
well as piston engines) and to a certain degree its electrical equipment and systems. This thesis
aims to include all types of corrosion that affect aircraft, identify critical areas that facilitate the
corrosion process, materials used and their suspectability towards corrosion, as well as
determining the means of protection. The thesis also includes a practical (experimental) section,
which aims to provide a laboratory analasys of specific components used on firefighting
aircrafts that suffered from damage attributed to corrosion.
