Abstract [en]

Nowadays naval units are participating in international missions, where new and in many cases tougher conditions will affect their propulsion.

 

This essay deals with some of the now developed nanostructure coatings and gives a presentation of how the coatings could function on some exposed parts of the naval powertrain. The essay investigates the possibility that the coatings can be used as a protective layer that will reduce or prevent wear on selected parts of the naval powertrains. As a basis for the essay, nanotechnology is described, as well as different reasons that wear occurs and application techniques for coatings

 

The conclusion is that nanostructured coatings can be applied and provide a much better result on hardness and wear resistance as of naval powertrains compared to micro-structural coatings, both for manufacturing and renovation.

 

The essay presents a few examples of the military utility of the nanostructure coatings as well as suggestions for further research.

Abstract [sv]

Då marina enheter numera deltar i internationella missioner, kommer den nya och i många fall tuffare miljön som enheterna opererar i att påverka bland annat deras framdrivning.

 

Den här studien avhandlar några av de nu framtagna nanostrukturella ytbeläggningarna och ger en presentation av hur de kan fungera på några marina drivlinors utsatta delar. Studien undersöker ytbeläggningarnas möjliga förmåga att utgöra ett skyddande lager som ska minska eller i bästa fall förhindra slitaget på valda delar av marina drivlinor. Som underlag till studien beskrivs i allmänna termer nanoteknik, olika anledningar till att slitaget uppstår samt något om hur ytbeläggningen kan appliceras.

 

Studiens slutsats är att det med all sannolikhet går att applicera nanostrukturella ytbeläggningar och få ett mycket bättre resultat avseende hårdhet samt nötnings- och reptålighet jämfört med mikrostrukturella ytbeläggningar. Detta gäller såväl vid nytillverkning som renovering av de studerade delarna av drivlinor.

 

Studien ger exempel på den militära nyttan med denna ytbeläggning samt ger förslag på fortsatt forskning.
