1. 1. Wear characterization and wear mapping of a coated cutting tool : Development of cutting tool test fixture and wear testing

   University essay from Karlstads universitet/Science, Mathematics and Engineering Education Research (SMEER)

   Author : Abdulbaset Mussa; [2015]
   Keywords : tribology; friction; sliding wear; coating;

   Abstract : Wear mechanisms of the cutting tools are well investigated worldwide. Usually researchers use the cutting process itself, turning by single point cutting, as their investigation method, which includes turning a metal cylinder with a pre-selected work-material and predetermined cutting conditions.

3. 2. Influence of tool steel carbide orientation on sliding wear

   University essay from Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Johanna Meseret Berhe Larsson; [2013]
   Keywords : ;

   Abstract : For SMF industry, galling of tool in SMF operation during forming of stainless steel is a major concern, this increase the interest to study influence of tool microstructure on galling. In the present work, ingot cast AISI D2 were evaluated concerning wear mechanisms and critical sliding distance against austenitic stainless steel sheet in lubricated sliding condition at different contact pressures using a slider-on-flat-surface (SOFS) tribometer for carbide phases oriented in three different directions.

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
