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

    University essay from KTH/Materialvetenskap

    Author : Vinayak Ramakrishnan Easwar; [2020]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from

    Author : Daniel Andersson; Mikael Ingvarsson; [2019-07-03T13:52:34Z 2019-07-03T13:52:34Z 2015]
    Keywords : Materialvetenskap; Produktion; Mekanisk tillverkningsteknik; Materials Science; Production; Mechanical manufacturing engineering;

    Abstract : 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. READ MORE

  6. 5. Material flows in the waterjet industry : an environmental perspective

    University essay from Linköpings universitet/Industriell miljöteknik; Linköpings universitet/Tekniska högskolan

    Author : Daniele Abbatelli; [2014]
    Keywords : waterjet; abrasive; LCA; Life Cycle Assessment; olivine; garnet;

    Abstract : Abrasive Waterjet cutting (AWJ) presents many advantages over competing machining techniques, but several issues are related to the high volume of materials (and in particular of abrasive) used in the process. In this study, the environmental impact of the material flows in the abrasive waterjet industry has been analyzed adopting a life cycle perspective in order to individuate which phases place the largest burden on the environment.
