  1. 1. Chromia-Alumina Thin Films from Alkoxide Precursors : From Precursor Synthesis to Deposition and Characterisation

    University essay from Uppsala universitet/Oorganisk kemi

    Author : Elina Elvelo; [2023]
    Keywords : alkoxide; synthesis; thin film; coating; alumina; chromia; spinodal decomposition;

    Abstract : A hetero-bimetallic alkoxide CrAl3(OiPr)12 was synthesised through metathesis of achromium(III)chloride THF complex (CrCl3 . 3 THF) and 3 KAl(OiPr)4.It was used as a single sourceprecursor to make oxide powders and films with 1:3 chromium/aluminium compositionthrough sol-gel synthesis.

  3. 2. A pre-study for functional coatings evaluated on light metals to be applied on a new HPDC Mg-alloy : Investigating tribological and thermophysical properties, as-cast and coated

    University essay from Jönköping University/JTH, Industriell produktutveckling, produktion och design

    Author : Louise Albo Zieme; Pontus Bergstedt; [2021]
    Keywords : reciprocating dry sliding wear test; thermophysical test; NiP-SiC; Ni-SiC; functional coatings; progressive scratch test; adhesion; magnesium alloy; aluminium alloy; hardness.;

    Abstract : Magnesium with two-thirds of the density compared to aluminium and one-quarter of steel, intrigues product developers and material scientists due to the light metal’s excellent combination of strength to weight ratio as well as their capability of being produced as a High Pressure Die Cast component compared to other ferrous or light metal alloys.   However, a magnesium alloy inherits some concerning drawbacks, limiting the exploitation in structural applications and mechanical design such as automotive, heavy machinery and aerospace components.

  4. 3. Modeling of carbon plasma discharges in high-power impulse magnetron sputtering

    University essay from Linköpings universitet/Plasma och ytbeläggningsfysik

    Author : Henrik Eliasson; [2021]
    Keywords : ;

    Abstract : Diamond like carbon (DLC) is a metastable state of amorphous carbon that has very important and wide-ranging thin film applications. DLC has a strong resemblance to pure diamond and exhibits many traits of real diamond, like mechanical hardness and chemical inertness, but with a drastically lower deposition cost. READ MORE

  5. 4. Aging of FeCrAl Surface Coatings

    University essay from KTH/Materialvetenskap

    Author : Fadi Alsaifi; [2019]

    Abstract : This Thesis is about the aging of FECRAL surface coatings. In this thesis various substrates have been investigated such as 16 Mo3, 304, 347, Sanicro 31, 800HT, Nikrothal 80 and Kanthal APMT. READ MORE

  6. 5. A Study of Various Parameters Affecting Adhesion of Coatings to Metal Substrates

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Worabhorn Pathanatecha; [2019]
    Keywords : adhesion; coatings; metal substrates; silanes; polyurethanes; surface energy; crosslinking agent; adhesion promoters; vidhäftning; beläggningar; metallunderlag; silaner; polyuretaner; ytenergi; tvärbindningsmedel; vidhäftningspromotor;

    Abstract : The adhesion of coatings is of high importance in the coating industry and a more thorough understanding of adhesion behavior is required. In this thesis work, seven parameters affecting adhesion of silane-modified poly(urethane urea) (PUSi) coatings on pretreated steel and aluminum substrates were studied. READ MORE
