Abstract

Ovaj rad bavi se problematikom korozije u aeronautici i astronautici, odnosno, korozijskim oštećenjima letjelica tijekom njihovog rada u zračnom prostoru, ali i na tlu, gdje su izložene raznoraznim okolišnim uvjetima i korozivnim čimbenicima. Svrha kontrole korozije u aeronautici i astronautici je spriječiti pojavu korozijskih oštećenja prikladnim preventivnim metodama i dizajnom, vizualnim pregledom utvrditi potencijalnu pojavu jednog ili više korozijskih oblika na letjelicama te korozijski produkt ukloniti i mjesto na kojem je došlo do korozije zaštititi od daljnjih utjecaja agresivnog okoliša. U tu svrhu koriste se premazivanje, oblaganje, inhibitori i procesi površinske obrade. Vizualni opisi, mjesta na kojima se pojedini korozijski oblici najčešće mogu naći te načini prevencije i zaštite najvažnijih dijelova letjelice od korozije objašnjeni su u ovom radu. Prikazani su primjeri katastrofalnih nesreća koje su posljedica nedostatka pažnje pri rješavanju problema korozijskih oštećenja, što je dovelo do velikih gubitaka letjelica i, nažalost, ljudskih života. Upravo to je bio značajan poticaj za istraživanje korozije i njezinih mehanizama, klasifikacije, kontrole i prevencije.

Abstract (english)

This paper deals with the issue of corrosion in aeronautics and astronautics, more specifically, corrosion damage to aircraft during their operation in the airspace, but also on the ground, where they are exposed to various environmental conditions and corrosion factors. The purpose of corrosion control in aeronautics and astronautics is to prevent the occurrence of corrosion damage using suitable preventive methods and design, to determine the potential occurrence of one or more corrosion forms on aircraft by visual inspection and to remove the corrosion product and protect the place where the corrosion occured from further effects of an aggressive environment. Coating methods, inhibitors and surface treatment processes are used for this purpose. Visual descriptions, places where certain forms of corrosion are most often found and ways to prevent and protect the most important aircraft parts from corrosion are explained in this work. Examples of catastrophic accidents resulting from a lack of attention in solving the corrosion problems, which led to great loss of aircraft and, unfortunately, human lives, are also presented. This was precisely the meaningful incentive for corrosion mechanisms, classification, control and prevention research.
