  4. 4. Growth and characterization of TiN/SiNx multilayer thin films

    Detta är en avhandling från Luleå tekniska universitet

    Författare :Hans Söderberg; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Materials; Materialteknik;

    Sammanfattning : The demands from industry for higher cutting speeds, feeding rates, and reduction of the use of cooling agents during turning and milling operations are increasing. Consequently the requirements on the cutting inserts are increasing and new advanced coatings that can withstand the higher temperatures and larger loads are highly sought after. LÄS MER
