11. Low-friction and wear-resistant carbon nitride coatings for bearing components grown by magnetron sputtering
Sammanfattning : The scope of this thesis is the investigation of magnetron sputtered carbon nitride coatings suitable for roller bearing components. The research field of tribology of bearings focuses on minimizing friction between components by improving the lubricants. LÄS MER
12. Determination of Coefficient of Friction and Anisotropy in Metalworking
Sammanfattning : .... LÄS MER
13. Friction in metal powder pressing : measurement and characterisation
Sammanfattning : The present work describes different methods for measuring and characterisation of friction in powder compaction process. A new test apparatus has been developed and presented which gives possibility of directly measurement of coefficient of friction during pressing from low to relative high density. LÄS MER
14. Mechanisms and Phenomena in Braking and Gripping
Sammanfattning : Applications relying on a high static friction include various types of fixtures, couplings, bolted joints, torsion joints, etc. The common characteristic of these applications is that they rely on the friction force to maintain the relative position of two mating surfaces. LÄS MER
15. Force measurements using scanning probe microscopy : Applications to advanced powder processing
Sammanfattning : The object of this thesis is to apply scanning probemicroscopy (SPM) to the field of advanced powder processing.Measurement of interparticle surface forces at conditionsrelevant to ceramic processing has been performed together withthorough studies of powder friction. LÄS MER
