2. 1. Wear mechanisms in sheet metal forming : Effects of tool microstructure, adhesion and temperature

   Author : Anders Gåård; Pavel Krakhmalev; Jens Bergström; Ulf Olofsson; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Galling; sheet metal forming; wear; friction; adhesion; temperature; Materialteknik; Materials Engineering;

   Abstract : The general trend in the car body manufacturing industry is towards low-series production and reduction of press lubricants and car weight. The limited use of lubricants, in combination with the introduction of high and ultrahigh-strength sheet materials, continuously increases the demands on the forming tools. READ MORE

6. 4. Surface Engineering in Sheet Metal Forming

   Author : Per Carlsson; Mikael Olsson; Niklas Axén; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Friction; wear; metal coated steel sheet; dry lubricants; galling; PVD coatings; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

   Abstract : In recent years, surface engineering techniques have been developed in order to improve the tribological performance in many industrial applications. In sheet metal forming processes, the usage of liquid lubricants can be decreased by using self lubricated tribo surfaces which will result in more environmentally friendly workshops. READ MORE

7. 5. A study on wear characteristics of high strength steels under sliding contact

   Author : Abdulbaset Mussa; Pavel Krakhmalev; Jens Bergström; Jens Hardell; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High strength steels; thread joint wear; punch wear; sliding wear; surface cracking; reciprocal sliding; fatigue; surface delamination; white etching layer; nano-structured layer; friction; Materialteknik; Materials Engineering;

   Abstract : In the last decades, significant improvements regarding the design, materials and technology of rock drills have been made. Likewise, in sheet metal forming, forming tools experience very high contact pressures when processing high strength steel sheets. READ MORE
