The book delves into the critical issue of high-temperature corrosion in coal-fired thermal power plants, focusing on water wall and super-heater corrosion at specific temperature ranges. It highlights the detrimental effects of prolonged exposure on boiler tubes, including loss of load-bearing capacity and reduced wall thickness due to corrosion. A detailed investigation of failed water tubes from a fluidized bed combustion boiler reveals that corrosion, primarily involving Fe2O3, is the main failure cause, alongside factors like overheating and erosion.

Focusing on its biomedical applications, hydroxyapatite (HA) is a key material for joint replacements and bone substitutes due to its structural and chemical resemblance to human bone. It promotes bone tissue growth and exhibits high bioactivity and biocompatibility. However, its mechanical properties limit its use to non-load bearing applications. HA coatings significantly enhance the bonding between implants and bone, facilitating a more natural integration with metallic substrates.

Die Studie untersucht die Verwendung von Naturfaserverbundwerkstoffen, insbesondere Reishülsen-Polypropylen-Verbundstoffen, zur Kostensenkung bei Kunststoffrohstoffen. Durch die Variation des Füllstoffvolumens und den Einsatz von Zusatzstoffen wie Talkum, Glimmer und Kalziumkarbonatpulver wurden neun unterschiedliche Proben erstellt. Mithilfe der Software Minitab 16 wurden verschiedene Entwürfe und Diagramme erstellt, um die mechanischen Eigenschaften, Biegefestigkeit und Schlagzähigkeit der Materialplatten zu analysieren und deren Verstärkung zu optimieren.
