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

    Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Mats Eriksson; [2014]
    Nyckelord :Tribology; sliding wear; hard chrome; electroless nickel;

    Sammanfattning : 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. LÄS MER

    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
