Abstract

Maskirni premazi pripadaju skupini organskih završnih premaza koji se nanose na prethodno zaštićenu podlogu; metalnom prevlakom i/ili temeljnim i vezivnim premazom. Na karoseriji vojnih vozila pružaju zaštitu od korozije i trošenja i omogućuju dugotrajni kamuflažni efekt. U radu se ispituju svojstva, brončano-zelenog NATO premaza RAL 6031 F9, koji se primjenjuje samostalno ili kao dio trobojnog sustava. U teorijskom dijelu rada opisani su postupci nanošenja i svojstva zaštitnih prevlaka i premaza na karoseriji vozila, osnovni mehanizmi korozije i trošenja premaza karakterističnih za navedeni premaz te metode ispitivanja fizikalnih, mehaničkih, triboloških i korozijskih svojstava zaštitnih premaza. U eksperimentalnom dijelu rada provedena su laboratorijska ispitivanja mehaničkih, fizikalnih, korozijskih i triboloških svojstava premaza na limu izuzetom iz uporabe te na uzorcima pocinčanog i ne pocinčanog lima.

Abstract (english)

Camouflage coatings on the body of military vehicles have a significant protective role in the tribocorrosive environment, maintaining the camouflage effect. Namely, camouflage coatings belong to the group of organic cover coatings that are applied to a previously protected surface; metal coating and/or base coat and primer. Therefore, RAL 6031 F9, a bronze-green NATO coating, which is applied alone or as part of a tricolor system, is eminent for the military industry. The theoretical part of the work depicts the application procedures and properties of protective coatings and paint on the vehicle body, the basic mechanisms of corrosion and wear of coatings and the methods of testing the physical, mechanical, tribological and corrosion properties of camouflage coatings. In the experimental part of the work, the mechanical, physical, corrosion and tribological properties of the camouflage coating were tested on the existing sheet metal and on samples of galvanized and non-galvanized sheet metal. Laboratory testing of the coating on atmospheric corrosion and on the resistance of the coating to impact and abrasion erosion was carried out. Relevant ISO or EN standards and recommendations are listed for all tests performed.
