1. Thermal Barrier Coatings : Durability Assessment and Life Prediction
Sammanfattning : Thermal barrier coating (TBC) systems are coating systems containing a metallic bond coat and a ceramic top coat. TBCs are used in gas turbines for thermal insulation and oxidation resistance. LÄS MER
2. Thermal Barrier Coatings : Failure Mechanisms and Life Prediction
Sammanfattning : Thermal barrier coatings (TBCs) use in the hot sections of gas turbine engine enables them to run at higher temperatures, and as a consequence, achieve higher thermal efficiency. For full operational exploitation of TBCs, understanding their failure and knowing the service life is essential. LÄS MER
3. Influence of paper properties and polymer coatings on barrier properties of greaseproof paper
Sammanfattning : Greaseproof paper has a dense structure and therefore provides a natural barrier against materials like fat and oils. The barrier is obtained by extensive refining of the pulp. LÄS MER
4. Design of Thermal Barrier Coatings : A modelling approach
Sammanfattning : Atmospheric plasma sprayed (APS) thermal barrier coatings (TBCs) are commonly used for thermal protection of components in modern gas turbine application such as power generation, marine and aero engines. TBC is a duplex material system consisting of an insulating ceramic topcoat layer and an intermetallic bondcoat layer. LÄS MER
5. Barrier Properties of greaseproof paper
Sammanfattning : The barrier properties of greaseproof paper are achieved by extensive beating of the fibres. This treatment results in high costs for energy, both as beating energy and drying energy. A full-scale trial has been performed to investigate the role of the pulp with respect to energy demand and the barrier properties of the final papers. LÄS MER
