  1. 1. Sliding wear performance of electroplated hard chromium and autocatalytic nickel-phosphorus coatings at elevated temperatures

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

    Author : Mats Eriksson; [2014]
    Keywords : Tribology; sliding wear; hard chrome; electroless nickel;

    Abstract : This thesis was written for a Swedish valve manufacturer to find out in what temperature regimes it was possible to replace electroplated hard chromium with autocatalytic electroless nickel-phosphorus. In this work the dry sliding wear properties of electroplated hard chromium and autocatalytic electroless nickel-phosphorus(10% P) were compared. READ MORE

  3. 2. Development of PDI plates for Industrial Applications

    University essay from Högskolan i Halmstad; Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Author : Muhammad Saad Siddiqui; Tahseen Iqbal; [2010]
    Keywords : point diffraction interferometer; point diffraction interferometry; PDI; PDI plates; semi-transparent plates; nickel chromium coating; absorption coefficient of nickel chromium; surface roughness; surface roughness measurement;

    Abstract : The aim of this Master’s Degree thesis project is to design and develop point diffraction interferometer plates. In this project the PDI plates are re-designed, changing the design which was used in previous projects in Halmstad University. The transparency of PDI plates can be controlled by coating them with NiCr film. READ MORE
