| Abstract (English): |
In the paper, the quality of the hard chrome plating on standard steel plates and shroud-fuel nozzle used in the aviation industry was examined, where the thickness of the coating, hardness, microscopic structure and resistance to bending were determined. The entire galvanization process involved chemical, electrochemical and mechanical preparation of the examined parts prior to chromating, while the chromating itself took place in a solution of chromic acid. The aim of the work is to obtain high-quality hard chrome coatings through the process of reparation of worn shroud-fuel nozzle, which will be able to replace commercial new parts in terms of quality and characteristics. Also, taking into account that some parts are no longer even commercially available, the reparation procedure should enable extended use of the same parts. [ABSTRACT FROM AUTHOR] |
| Abstract (Bosnian): |
U radu je ispitan kvalitet prevlake tvdog hroma na etalonskim čeličnim pločicama i plaštu brizgača goriva koji je korišten u avioindustriji, pri čemu je određena debljina prevlake, tvrdoća, mikroskopska struktura i otpornost na savijanje. Ukupan proces prevlačenja podrazumjevao je proces mehaničke, hemijske i elektrohemijske pripreme ispitivanih dijelova prije procesa hromiranja, a proces hromiranja proveden je u rastvoru hromne kiseline. Cilj rada je dobiti kvalitetne prevlake tvrdog hroma postupkom reparacije istrošenog plašta brizgača goriva koji će kvalitetom i karakteristikama moći zamjeniti komercijalne nove dijelove. Također, uzimajući u obzir da pojedini dijelovi nisu više ni komercijalno dostupni uvođenje postupka reparacije treba omogućiti produženo korištenje istih dijelova. [ABSTRACT FROM AUTHOR] |
