  2. 2. Wear in sheet metal forming

    Author : Anders Gåård; Pavel Krakhmalev; Jens Bergström; Åsa Kassman; Karlstads universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Friction; Sheet metal forming; Galling; Materials science; Teknisk materialvetenskap; 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 press lubricants, in combination with the introduction of high and ultra-high strength sheet materials, continuously increases the demands of the forming tools. READ MORE

    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

  4. 4. The early stage of galling

    Author : Patrik Karlsson; Pavel Krakhmalev; Anders Gåård; Braham Prakash; Örebro universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Galling; Stainless steel; Tool steel; Friction; Sliding wear; SOFS; Tribology; Wear; Materialteknik; Materials Engineering;

    Abstract : In sheet metal forming (SMF) of materials such as stainless steels there is a major problem with transfer and accumulation of sheet material to the metal forming tool surface. The problem is known as galling; a kind of severe adhesive wear, which results in severe scratching of produced parts. READ MORE
