Sammanfattning :
Reduction of heat loss from the combustion chamber in an engine has great potential to decrease fuel consumption and CO2 emissions. Research on thermal barrier coatings (TBC) has been performed since the early eighties to address this potential. LÄS MER

Författare :Per Bengtsson; R. Taylor; Linköpings universitet; []
Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;
Sammanfattning :
Thermal barrier coatings (TBCs), with a thickness of 0.4 mm, are today extensively used on the hot parts of both stationary and flying jet engines. The purpose of the TBC is to protect the underlying material from high temperatures and severe thennal shock. LÄS MER

Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Barrier Coatings; Suspension Plasma Spraying; Gadolinium Zirconate; Internal Combustion Engines; Engine Efficiency; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;
Sammanfattning :
The upward trend in internal combustion engine efficiency is likely driven by the depletion of fossil fuels. Since no replacement in sight can deliver energy comparable to the conventional oil, there is a need to use it more rationally and effectively. LÄS MER

Sammanfattning :
Soft matter, here, liquids and polymers, have adaptability to a surrounding geometry. They intrinsically have advantageous characteristics from a mechanical perspective, such as flowing and wetting on surrounding surfaces, giving compliant, conformal and deformable behavior. LÄS MER
