  1. 1. Mechanical and tribological characterization of additive manufactured Co-alloyed tool steels aimed for cutting tool bodies

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Jijesh Rajan; [2022]
    Keywords : Maraging steels; Selective laser melting; microstructure; wear; Modified 18Ni300; Osprey MAR;

    Abstract : A drill tool body operates under tough cutting conditions where it is subjected to severe rubbing at the drill flute margin by the sliding chips. The tool wear caused by the contact stresses of the high-speed sliding chips is one of the common damage mechanisms observed in drill tool bodies. READ MORE

  3. 2. Mechanical and tribological characterization of additivemanufactured Co-free tool steels aimed for cutting tool bodies

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Mayur Mane; [2021]
    Keywords : Co-free maraging steels; Co-free W360 AMPO alloy; hot-work tool steel; Selective laser melting; microstructure; wear;

    Abstract : Additive manufacturing (AM) is an emerging and interesting technology that enables some of theproduct development projects (PDPs) to produce products that have mechanical and tribologicalproperties comparable to products that are conventionally manufactured. Selective laser melting(SLM) is an additive manufacturing technology that is predominantly used for the production of metalbased components (i. READ MORE

  4. 3. Correlating the microstructure with wear properties of aluminium silicon carbides

    University essay from Högskolan i Jönköping/JTH, Industriell produktutveckling, produktion och design; Högskolan i Jönköping/JTH, Material och tillverkning

    Author : Chaitanya Krishna Jammula; [2019]
    Keywords : Aluminium silicon carbide; silicon carbide; wear test and scratch test;

    Abstract : Aluminium is one of the metals playing a prominent role in automobile industry after cast iron. Because of its light weight property and good mechanical properties. When aluminium reinforced with silicon carbide showing good tribological properties and improved strength. READ MORE

  5. 4. Microstructural, Mechanical and Tribological Studies of Ti-6Al-4V Thin Plates Produced by EBM Process

    University essay from Högskolan Dalarna/Materialteknik

    Author : Onimisi Calistus Sanni; [2019]
    Keywords : Additive manufacturing AM ; Electron beam melting EBM ; Mechanical properties; Tribological behaviour; Microhardness; Micro tensile; Thin sections; Ti-6Al-4V;

    Abstract : The titanium alloy, Ti-6Al-4V, is vastly studied and used in many applications because it has a transformation microstructure, which can be tailored for apt properties that are consistent up to 500°C. Compared to conventional steels, this alloy favours certain applications due to its high specific strength, hardenability, corrosion resistance, biocompatibility and weldability. READ MORE

  6. 5. Relations between the performance of a coated cutting tool and the composition and properties of the wear resistant coating : A study including first principles modeling, mechanical properties and technological testing

    University essay from Materialteori; Institutionen för kemi - Ångström

    Author : Maria Bryngelsson; [2013]
    Keywords : Thin film; coating; wear; density functional theory; first principles; ab initio; turning;

    Abstract : This thesis work was performed at AB Sandvik Coromant and aimed to enhance the knowledge about the relationships between the performance of TiN and TiAlN-coated cutting tools in metal turning and their mechanical and chemical properties. Measurements of coating material properties and turning wear tests in annealed tool steel Sverker 21, stainless steel 316L, grey cast iron V314 and nodular cast iron SS0727 were performed. READ MORE
