1. Influence of Surface Carbon Content on the Wear of Threaded Connections in Rock Drilling Steels
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : This thesis work was conducted at Luleå University of Technology in collaboration with Sandvik Rock Tools. The aim of the work was to determine the influence of carbon content on the wear performance in carburized steel in the dry contact interface of threaded connections between drill rods. LÄS MER
2. Development of a method for estimation of contact fatigue life in hypoid gears
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : Hypoid gears have been used extensively in automobiles, aerospace, marine and other applications for decades. The special advantages of hypoid gears come with inherent contact complexities of varying curvature and sliding in both profile and lengthwise direction. LÄS MER
3. EB-PBF additive manufacturing of Alloy 718 : Effect of shot peening on surface characteristics and high temperature corrosion performance
Magister-uppsats, Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och MaskinteknikSammanfattning : There is an upsurge of research interest on Alloy 718 additively manufactured (AM) by electron beam powder bed fusion (EB-PBF) technique in aero and land-based gas turbine engines. However, the surface quality of the manufactured components has always been a major challenge. LÄS MER
4. Modeling and Analysis of the Shot Peening Process : a Study of the Residual Stresses in an Insert using the Finite Element Method
Magister-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)Sammanfattning : Cutting tool inserts are often coated with thin layers either through chemical vapor deposition (CVD) or physical vapor deposition (PVD) processes. In order to have a better wear resistance cutting tools are mostly subjected to post-coating treatment processes. LÄS MER
5. Methods to create compressive stress in high strength steel components
Kandidat-uppsats,Sammanfattning : Residual compressive stresses can be used to increase the lifetime of parts under cyclic stress as they negate the applied tensile stresses that cause crack initiation and propagation in the material. The goal of this project was to investigate methods to induce stresses, their advantages and disadvantages as well as depth and magnitude of induced stresses, and also to find methods of analyzing the induced residual stresses.
