1. Additives in a steam engine to decrease friction : Friction testing of solid lubricants in powder form
Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Sammanfattning : This thesis aims to investigate the coefficient of friction between steel on steel contacts with the addition of solid lubricants such as h-BN, WS2, MoS2 in powder form, in dry conditions and wet conditions. More specifically, the purpose is to enhance the sliding between the piston rings and cylinder block in a modern high temperature steam engine developed by RANOTOR. LÄS MER
2. Standardization in additivemanufacturing : Recommended parameters and fixture solutions for hybrid printing
Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : This study analyses and examines the hybrid printing process at Uddeholms AB in Hagfors.The objective of this study is to present recommended parameters to achieve optimal printingresults in a newly developed steel as well as a steel powder material designed for additivemanufacturing.

3. Magnetic properties of a martensitic stainless steel powder : Investigation of magnetic properties for a metallic powder with different sizes and its possible correlation to flow properties
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : For metal powders, flow properties are important. If the powder does not move properly, it can result in problems with the final product in additive manufacturing. Some of the products created with this manufacturing method are complex and used for important purposes such as medical devices and aerospace. LÄS MER
4. Can iba detect the next compressor failure? : Condition-based monitoring applied to nitrogen compressor – a case study
Master-uppsats, Högskolan i Gävle/ElektronikSammanfattning : Production of steel powder is done by atomization of a molten steel stream. Atomization is done by feeding high pressure nitrogen gas through nozzles, creating jets of gas which scatter the molten steel stream into powder. The steel powder falls through the atomization tower whilst it cools and solidifies. LÄS MER
5. Simulation and Experimental Based Hardenability Evaluation of Chromium Alloyed Powder Metal Steels
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Powder metallurgy is a branch of metal forming technology where metal powders are used to manufacture parts and components. It is a flexible and economical technique for manufacturing complicated shapes. This present work focuses on press and sinter technology and forms a part of Höganäs’s efforts of modelling hardenability through quenching. LÄS MER
