    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Sofie Wallin; [2015]
    Keywords : ;

    Abstract : This report presents a method for transport simulation of infusion bags. A cardboard box filled with infusion bags have been vibrated with an in house developed shake rig, using fixed frequency and horizontal direction. READ MORE

  3. 32. Tool wear in turning titanium alloys

    University essay from Uppsala universitet/Institutionen för kemi - Ångström

    Author : Magnus Johansson; [2015]
    Keywords : Titanium machining; Tool wear; Crater wear; Turning; WC Co cutting tool;

    Abstract : In this master thesis, performed at AB Sandvik Coromant, wear and tool life of uncoated WC/Co grades have been investigated during longitudinal turning of the titanium alloy Ti-6Al-4V. Due to titanium’s poor thermal conductivity and high chemical reactivity towards most metals, high temperature is achieved between the tool and workpiece material, resulting in high tool wear rates.

  4. 33. Effect of tungsten carbides properties of overlay welded WC/NiSiB composite coatings

    University essay from KTH/Industriell produktion

    Author : Richard Seger; [2014]
    Keywords : ;

    Abstract : To get a long life of a product which is subjected to heavy mechanical wear, materials with particularly good properties such as high hardness and the ability to resist high temperature is required. Tungsten carbide is a material which has these properties, but to manufacture large products for mining industry or agriculture entirely of this material is neither practical nor quite beneficial when the disadvantages of the materials such as brittleness, high weight and high price will have a major affect.

  5. 34. Protective coatings for Al press tools used in automotive industry

    University essay from Högskolan Väst/Avd för tillverkningsprocesser

    Author : Ruoyo Tan; [2014]
    Keywords : Protective coating; HVAF; APS; Aluminium substrate; Wear resistance;

    Abstract : The application of the thermally sprayed WC-Co and Cr 3C2-NiCr coatings have been widely used in industry for its superior sliding, abrasive and erosive wear properties. The Al2O3 coating possessing high hardness can be utilized to improve the wear resistance of the metallic surface. READ MORE

  6. 35. Wear testing of high-alloy carbon steel used in mining tools

    University essay from KTH/Materialvetenskap

    Author : Sara Olsson; Linn Efsing; [2013]
    Keywords : Wear; Wear-testing methods; Adhesive wear; Abrasive wear; Nötning; Nötningstester; Adhesiv nötning; Abrasiv nötning;

    Abstract : Wear is a commonly occurring degradation mechanism for materials and components in the rock drilling industry. The wear can occur by either abrasion or adhesive wear. Further corrosion and presence of water or other lubricating fluids with or without particles may influence the behavior. READ MORE
