   Abstract : Out of the 17 Sustainable Development Goals (SDGs) adopted by the United Nations in 2015, chemicals and waste management are obtainable under six. Improper and unsafe disposal of toxic chemicals into the environment affects life below water (SDG 14), human health and well-being (SDG 7), and clean water and sanitation (SDG 6). READ MORE

4. 3. Tribological characterization of selected hard coatings

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

   Author : Patrik Karlsson; [2009]
   Keywords : Tribology;

   Abstract : Hard coatings are often used for protection of tool surfaces due to coating properties like low friction and high wear resistance. Even though many of the hard coatings have been tested for wear, it is important to try new wear test setups to fully understand tribological mechanisms and the potential of hard coatings. READ MORE

5. 4. 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
