1. 1. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Ahsan Ali; [2023]
   Keywords : High temperature tribology; Early-stage adhesion; Adhesive wear; Friction; Wear resistant coatings; Physical vapour deposition PVD coatings; TiAlN; Tungsten carbide WC Co ; Difficult to machine super alloys; Inconel 718; Stainless steel 316L; High-performance materials; Abrasion; Oxidation; Chipping; Ploughing; Characterization;

   Abstract : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

4. 3. Evaluation of Refined Tribological Properties of Diamond Coated Cutting Tools Used in Machining of High-Strength Aluminum Alloys : Master thesis report regarding refined frictional & wear behavior of uncoated & CVD diamond coated WC-Co cemented carbide cutting tools used for machining of Al 7xxx alloys.

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Christian Hultman; [2022]
   Keywords : tribology; machining; metal cutting; turning; milling; friction; wear; material transfer; surface technology; tribologi; skärande bearbetning; svarvning; fräsning; friktion; förslitning; nötning; materialöverföring; ytteknologi;

   Abstract : High strength aluminum alloys have for a long time been a popular material utilized in the automotive and aerospace sector due to coveted mechanical properties in terms of weight, strength, fatigue, and corrosion. However, tribological mechanisms such as tribo-film formation and material transfer during the metal cutting manufacturing process of aluminum impose significant reduction of machining and tool-life performance.

5. 4. Atomic wear mechanisms of hard chrome against Al2O3

   University essay from Malmö universitet/Fakulteten för teknik och samhälle (TS)

   Author : Raul Fierro Tobar; Marius Yuku; [2021]
   Keywords : Wear mechanisms; DFT; MD; hard chrome; aluminium; RDF; adhesive; abrasive; Nötning; DFT; MD; hårdkrom; aluminium; RDF; adhesiv; abrasiv;

   Abstract : Hard chrome exhibit hardness of about 70 HRC and lubricity that prevents seizing and galling and is therefore the common first choice for engineers to reduce friction and minimize wear. These properties enable engineering applications such as cutting and drilling, especially in manufacturing, production and consumer good industries. READ MORE

6. 5. Mapping and characterisation of surface damage and wear mechanisms in gun barrels : Gun barrels exposed to cyclic thermo-mechanical loading

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Martin Perkovic; [2020]
   Keywords : Wear; erosion; sliding wear; gun barrel; characterisation;

   Abstract : Gun barrels are an important component in advanced defence systems. The gun barrels are used for direct and indirect fire and the material of the gun barrel is exposed to great strains and high temperatures. This sets high demands on the material of the gun barrel. During firing the gun barrel can be damaged. READ MORE
