  1. 41. An Investigation in Binder Jetting of Copper Graphene Composites

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Rajat Gulabrao Kawalkar; [2022]
    Keywords : inder Jetting; Sintering; Copper Composite; Copper Reference; Density; Graphene;

    Abstract : The purpose of this work is to explore the feasibility of using binder jetting to print copper-graphene composites. This work discusses in detail the approach used to print the composite samples which are optimised through various processes to generate denser parts than a copper reference print and finally discussing various opportunities to enhance development of the process.

  3. 42. Effect of post-treatment of cemented carbide : Microstructural investigation and evaluation of mechanical properties of cemented carbide inserts for rock tool applications

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Jessica Jacobs; [2021]
    Keywords : ;

    Abstract : Cemented carbides are used in rock tool applications by reason of their beneficial mechanical properties, i.e. a combination of high toughness, wear resistance and hardness. The cemented carbides commonly receive their hardness from tungsten carbides (WC) whereas cobalt (Co) is the dominating binder material. READ MORE

  4. 43. Correlation Between Microstructural And Mechanical Properties In Niobium Carbide Reinforced Hadfield Steel Composites

    University essay from Lunds universitet/Industriell Produktion

    Author : Lakshmi Manogna Dama; [2021]
    Keywords : Metal Matrix Composites MMCs ; Hadfield steels; Reinforcement; Technology and Engineering;

    Abstract : Degradation of tools is a prevalent aspect in the mechanical world; due to the advancement of technologies and intense research and development, there are new ways and ideas to curb or delay the tool failures; one such idea is to implement Metal Matrix Composites (MMCs) with various reinforcement materials. This thesis focuses on improving the hardness and wear resistance of Hadfield steel by reinforcing it with Niobium Carbide (NbC). READ MORE

  5. 44. Tribological Performance of Ferritic Nitrocarburizing (FNC) Treated Automotive Brake Discs

    University essay from Lunds universitet/Industriell Produktion

    Author : Chandan Kumar Ravindra Reddy; Shanmukharaj Jayasankar; [2021]
    Keywords : Tribology; Gray Cast Iron; Ferritic NitroCarburized; Coefficient of Friction; Wear.; Technology and Engineering;

    Abstract : The increase of electric vehicles in the market demands the automotive industries to search for better brake disc material with high wear resistance, corrosion resistance, and longer service life. The GCI brake discs, a traditionally used material that has less wear and corrosion resistance. READ MORE

  6. 45. 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
