Analysis of laser cladding of used brake discs (English)
Abstract [sv]

Detta arbete undersöker om metoden ’laser cladding’ skulle kunna användas för att möjliggöra återanvändandet av bromsskivor som annars skulle deponeras. Olika material undersöks ur ett miljöperspektiv, det vill säga energiåtgång och CO2-utsläpp jämförs mot en vanlig gjutjärnsskiva. För att göra detta användes programmet CES EduPack samt ytterligare beräkningar med formler som komplement då programmets databas inte är heltäckande gällande specifika materialvarianter. För att lättare kunna beräkna massor användes CAD-programmet Solid Edge för att modellera en typisk bromsskiva. Resultatet blev att laserbeläggning på utslitna bromsskivor sparar på både energi och avger mindre CO2-avtryck, förutsatt att rätt tillsatsmaterial väljs. Som mest kunde en minskning med 80,5% uppnås i energiåtgång respektive 88% för CO2-utsläpp under materialframställning och tillverkning. Metoden medför alltså tydliga positiva miljömässiga effekter.

Abstract [en]

This report investigates Laser Cladding and especially the possibility to coat worn brake discs. A selection of materials are studied with an environmental point of view in focus, the life cycle of the coated brake discs are compared to a standard new gray cast iron brake disc. The program CES Edupack is used for the life cycle analysis and it is completed by formulas of energy consumption and CO2 footprint because not all processes and materials are included in the software. Solid Edge is used to create a CAD model of a typical brake disc to easily exam the volume and weight of the disc as a function of the thickness. The result is laser cladding on worn brake discs saves energy and produces a smaller carbon footprint if the right powders used for cladding are chosen. Laser cladding with stainless steel powders provided the best results with 80.5% savings in energy consumption and 88% in CO2-footprint savings. The laser cladding technique shows clear positive environmental effects.
