  1. 1. An Investigation into 'Squeezing'or Three-Body Wear caused by Abrasive Particles

    Master-uppsats, KTH/Materialvetenskap

    Författare :Vinayak Ramakrishnan Easwar; [2020]
    Nyckelord :;

    Sammanfattning : Material wear is an ever present phenomenon and can never be completely removed in systems of moving parts. There will always be friction between materials, causing degradation of these materials and eventually the material will be worn out and have to be replaced. LÄS MER

  3. 2. Design of Experiment and Evaluation of Abrasive Waterjet Cutting in Titanium Alloy Sheet

    H-uppsats,

    Författare :Daniel Andersson; Mikael Ingvarsson; [2019-07-03]
    Nyckelord :Materialvetenskap; Produktion; Mekanisk tillverkningsteknik; Materials Science; Production; Mechanical manufacturing engineering;

    Sammanfattning : High demands on components in the aerospace industry empower the use of advanced manufacturing processes in order to increase quality and reduce costly processing steps. This includes non-conventional machining such as Abrasive Waterjet where the components are cut through abrasive impingement by means of abrasives accelerated by pressurized water. LÄS MER
