1. 1. Modeling of carbon plasma discharges in high-power impulse magnetron sputtering

   Master-uppsats, Linköpings universitet/Plasma och ytbeläggningsfysik

   Författare :Henrik Eliasson; [2021]
   Nyckelord :;

   Sammanfattning : Diamond like carbon (DLC) is a metastable state of amorphous carbon that has very important and wide-ranging thin film applications. DLC has a strong resemblance to pure diamond and exhibits many traits of real diamond, like mechanical hardness and chemical inertness, but with a drastically lower deposition cost. LÄS MER

3. 2. SUSTAINABLE LUBRICATION FOR FUTURE TRANSMISSIONS : Micropitting performance of Glycerol-based lubricants

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Zapata Tamayo Juan Guillermo; [2021]
   Nyckelord :micropitting; mild sliding wear; surface coating; diamond-like carbon DLC; glycerol-based lubrication; green lubricant; rolling contact fatigue; rolling-sliding;

   Sammanfattning : Achieving sustainable lubrication by using environmentally friendly formulated lubricants has became an essential component of the transition process from fossil-powered vehicles to electrified transportation. Mixtures, or aqueous solutions of molecules such as polyhydroxy alcohols, and glycols usually known as green lubricants make it possible to achieve low friction coefficients under different lubrication conditions, which constitutes a potential alternative to improve the tribological performance of moving parts in automotive systems, at the same time that the environmental requirements are satisfied.

4. 3. Structural Investigations of HiPIMS-deposited Diamond-Like Carbon Thin Films using Raman Spectroscopy

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

   Författare :Andreas Eriksen Tell; [2017]
   Nyckelord :;

   Sammanfattning : Diamond-like carbon (DLC) is a versatile material which exhibits excellentmechanical, electrical and optical properties making it suitable for applications rangingfrom biomedical implants to engine components. The properties of DLC thin films aredetermined by the bonding configuration (sp3/sp2 fraction) of its carbon atoms. LÄS MER

5. 4. Tribological testing of DLC coatings for automotive applications

   Uppsats för yrkesexamina på avancerad nivå, Tillämpad materialvetenskap

   Författare :Viktor Renman; [2012]
   Nyckelord :DLC; wear; friction; tribology; diamond-like carbon; automotive; engine oils; fuels;

   Sammanfattning : In this work, the friction and wear behavior of three DLC coatings was evaluated in various conventional and alternative fuels as well as in commercially available formulated engine oils and additive-free synthetic oil. The first DLC has a thin top-coating of hydrogenated amorphous carbon (a-C:H), the second consists of Si-doped DLC (a-C:H:Si) and the third is a W-doped multilayered structure of a-C:H and a-C:H:W.
