6. 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
7. High Temperature Corrosion of FeCrAl Alloys: The influence of water vapour and alkali salt
Sammanfattning : The corrosive environment in biomass- and waste-fired boilers has been known for several years. The traditionally used FeCr and FeNiCr steels show limited performance in the aggressive environment that contains more H2O and alkali salts than traditional fuel. LÄS MER
8. High-temperature corrosion properties of chromia- and alumina-forming alloys
Sammanfattning : Electricity production, transportation, and manufacturing industry are some of the largest sources of greenhouse gas emissions. In many cases, these processes are carried out at high temperature and energy efficiency is limited by material degradation, so-called ‘high-temperature corrosion’. LÄS MER
9. Oxidation, Creep and Fatigue Synergies in Cast Materials for Exhaust Manifolds
Sammanfattning : The future development of engines of heavy-duty vehicles towards reduced CO2 emission will increase the exhaust gas temperature and render the exhaust atmosphere more corrosive. The current service material of exhaust gas components - a ferritic ductile cast iron called SiMo51 - will soon meet its upper-temperature limit. LÄS MER
