  1. 21. Surface Treatment of Photocatalyst Metal Supports for VOCs Abatement Applications

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Don Chinungi; [2016]
    Nyckelord :;

    Sammanfattning : In this work, the preparation of photocatalysts’ metal support for applications in purification of industrial gas emissions has been studied. The supports normally used in literature are ceramics, but they are not suitable for industrial applications. LÄS MER

  3. 22. Adhesion of CVD coatings on new cemeted carbides

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Eric Bojestig; [2016]
    Nyckelord :cemented carbide; adhesion; alternative binder phase; CVD coating; hard metal;

    Sammanfattning : Steel turning inserts cemented carbides have a binder phase consisting of cobalt (Co). However, in recent years a study from the United States National Toxicity Program (NTP) found that cobalt powder is carcinogenic upon inhalation. The European Union's REACH have therefore also classified cobalt powder as carcinogenic upon inhalation. LÄS MER

  4. 23. Characterization of a newly developed martensitic stainless steel powder for Laser and PTA cladding

    Magister-uppsats, KTH/Materialvetenskap

    Författare :Fritjof Tibblin; [2015]
    Nyckelord :Martensitic stainless steel; steel powder; laser cladding; PTA cladding;

    Sammanfattning : A newly developed martensitic stainless steel powder, called “powder A”, designed for surface coating with laser cladding and PTA cladding was characterized. The purpose with powder A is to achieve both good corrosion resistance and wear resistance in a stainless steel grade. LÄS MER

  5. 24. Plasma sprayed cylinder lining coatings : Factors affecting the amount of ceramics in plasma sprayed cylinder lining coatings

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Hermina Antonsson Nilsson; Tova Jarnerud; [2015]
    Nyckelord :Scania; plasma; cylinder; foder; beläggning;

    Sammanfattning : Scania uses powder plasma spray technology to coat their cylinder linings. The powder used contains stainless steel and ceramics. In order for the properties of the coating to reach the quality demands, it has to have a certain amount of pores and ceramics in it. LÄS MER

  7. 25. Effect of tungsten carbides properties of overlay welded WC/NiSiB composite coatings

    Master-uppsats, KTH/Industriell produktion

    Författare :Richard Seger; [2014]
    Nyckelord :;

    Sammanfattning : To get a long life of a product which is subjected to heavy mechanical wear, materials with particularly good properties such as high hardness and the ability to resist high temperature is required. Tungsten carbide is a material which has these properties, but to manufacture large products for mining industry or agriculture entirely of this material is neither practical nor quite beneficial when the disadvantages of the materials such as brittleness, high weight and high price will have a major affect.
