1. 1. On the friction and failure mechanisms of bearing and gear surfaces lubricated by a novel nanoadditive in highly stressed operating conditions

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Diego Manuel Chamorro Ruz; [2022]
   Keywords : micropitting; nanoadditive; gear; bearing; tribology; rolling contact fatigue;

   Abstract : Obtaining an enhanced lifespan for mechanical transmissions has become a challenge in diverse application sectors. Micropitting as a contact fatigue mechanism has seriously jeopardized the well-being of rolling-sliding elements present for instance in gearboxes. READ MORE

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

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

   Abstract : 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. Tribological evaluation of the contact between upper compression ring and cylinder liner with different surface coatings

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik

   Author : Pär Wassborg; [2016]
   Keywords : piston ring; cylinder liner; wear; friction; grey cast iron; titanium oxide; chromium oxide;

   Abstract : The constant pursuit in the automotive industry to increase the engines performance, new solutions are always developed and tested to reduce the friction and increase the efficiency in the engine. One component that contributes to friction losses is the piston ring pack where the top compression stands for up to 40 %. READ MORE

5. 4. Mild impact wear in a concrete mixer : An evaluation of wet abrasive wear

   University essay from KTH/Materialvetenskap

   Author : m Jungedal; [2012]
   Keywords : Wear; wet abrasive wear; mild impact wear; steel;

   Abstract : The concrete mixer industry is affected by abrasive wear under both dry and wet conditions. An upgrade of the material inside the drums to high abrasion resistant steel grades can improve the lifetime and offer the possibility to reduce the weight of the drum. READ MORE

6. 5. An investigation of friction graphs ranking ability regarding the galling phenomenon in dry SOFS contact : (Adhesive material transfere and friction)

   University essay from Karlstads universitet/Fakulteten för teknik- och naturvetenskap

   Author : Harald Wallin; [2008]
   Keywords : galling; friction; adhesive contact; mild adhesive; severe adhesive; abrasive; flattening; SOFS; TNO; slider on flat surface; tribology; dry; lubricated; frictional heating; acceleration; plastic zone; contact pressure; pressure; phase transformation; morphology; seizure; scoring; scuffing; cohesive forces; classification; characteristic patterns; lump; sheet damage; på kletning; friction; kontakt tryck; värme; plogning;

   Abstract : The main purpose of this project is to investigate different tool steels in terms of their ability to withstand material transfer buildup, so-called galling, occurring in SMF (sheet metal forming) operations. The ability to withstand galling is vital to optimize cost-effectiveness and increase the work tool’s effective operational time. READ MORE
