31. High Temperature Corrosion of Cast Irons and Steels
Sammanfattning : During the last decades, tougher competition and stiffer government policies have forced the automotive industry into a race for safer, cleaner and more fuel-efficient vehicles at low cost. As a consequence, exhaust systems should resist to increased working temperatures. LÄS MER
32. Corrosion of Ferritic Stainless Steel Interconnects for Solid Oxide Cells – Challenging Operating Conditions
Sammanfattning : Solid oxide cells (SOC) have the potential to revolutionize electricity production by being able to both produce electricity with very high efficiency from a variety of fuels or to produce fuels from electricity and abundant raw materials such as water or carbon dioxide. Some material challenges remain to be solved before large-scale commercialization can be achieved. LÄS MER
33. Metal release from stainless steel and CoCrMo alloys in protein-rich environments – effects of protein aggregation, friction, and irradiation
Sammanfattning : Highly corrosion-resistant alloys are used in sensitive environments such as the human body and food environments. However, even tiny amounts of released metals from these surfaces could potentially cause adverse effects. It is hence important to study the biointerface between corrosion-resistant alloys and protein-rich environments. LÄS MER
34. Steel fibre corrosion in cracks : durability of sprayed concrete
Sammanfattning : Steel fibre reinforced sprayed concrete is common practice for permanent linings in underground construction. Today there is a demand on "expected technical service life" of 120 years. Thin steel fibres could be expected to discontinue carrying load fast with a decrease of fibre diameter caused by corrosion, especially in cracks. LÄS MER
35. Corrosion Fatigue of Stainless Steels
Sammanfattning : The aim of this work was to investigate the effect ofchloride-containing environments on corrosion fatigueproperties for different stainless steels grades. The steelsinvestigated ranged from the standard 304 grade to thesuperaustenitic 654SMO and the superduplex SAF2507. LÄS MER
