16. Tribology for Greener Combustion Engines : Scuffing in Marine Engines and a Lubricating Boric Acid Fuel Additive
Sammanfattning : This thesis aims at increased knowledge in two fields of tribological research; both related to making currently used combustion engines greener. The first field regards the possibilities of using a boric acid fuel additive to increase fuel efficiency. LÄS MER
17. Formation and Function of Low-Friction Tribofilms
Sammanfattning : The use of low-friction coatings on machine elements is steadily increasing, and they are expected to play an important role in the reduction of fuel consumption of future motorized vehicles. Many low-friction coatings function by transformation of the outermost coating layer into tribofilms, which then cover the coating surface and its counter surface. LÄS MER
18. Development of New Multiscale Polymer Composites for Water Lubricated Tribological Contacts
Sammanfattning : Moving towards a Green Economy, there is a growing demand to use environmentally friendly tribological systems that has resulted in industries turning towards new mate-rials and water-based lubrication to satisfy their needs. Considering the low viscosity of water, tribological contacts lubricated with it are likely to operate in boundary/mixed lubrication regime for relatively long periods. LÄS MER
19. Simulation of tribology in hydraulic motors
Sammanfattning : Tribology is the science of friction, lubrication and wear. A tribological interface is composed of two contacting surfaces in relative motion. The radial piston hydraulic motor includes a lot of tribological interfaces. LÄS MER
20. Tribology of Rolling-Sliding Contacts under Mixed Lubrication : With focus on a Crankshaft Roller Bearing Application
Sammanfattning : A continuous increase in environmental legislation to reduce CO2 emissions is forcing engineers and scientists to develop more efficient and durable mechanical components, i.e. bearings, crankshafts, gears, etc. LÄS MER
