Description: High Temperature Coatings demonstrates how to counteract the thermal effects of the rapid corrosion and degradation of exposed materials and equipment that can occur under high operating temperatures. This is the first true practical guide on the use of thermally-protective coatings for high-temperature applications, including the latest developments in materials used for protective coatings. It covers the make-up and behavior of such materials under thermal stress and the methods used for applying them to specific types of substrates, as well as invaluable advice on inspection and repair of existing thermal coatings. With his long experience in the aerospace gas turbine industry, the author has compiled the very latest in coating materials and coating technologies, as well as hard-to-find guidance on maintaining and repairing thermal coatings, including appropriate inspection protocols. The book will be supplemented with the latest reference information and additional support for finding more application-type and industry-type coatings specifications and uses, with help for the reader in finding more detailed information on a specific type of coating or a specific type of use. Offers overview of the underlying fundamental concepts of thermally-protective coatings, including thermodynamics, energy kinetics, crystallography, and equilibrium phases Covers essential chemistry and physics of underlying substrates, including steels, nickel-iron alloys, nickel-cobalt alloys, and titanium alloys Provides detailed guidance on wide variety of coating types, including those used against high temperature corrosion and oxidative degradation, as well as thermal barrier coatings

High Temperature Coatings

Organisations and marketers have long debated the consumer–brand relationship. Theorising related to this debate led to self-service technologies, which were implemented to both reduce costs and increase productivity by turning customers into co-producers of services or merely to keep up with technological developments. With the emergence of disruptive technologies, it is imperative to discuss the potential shift from a customer co-created value to a customer–technology relationship that could disrupt the value-based relationship model. In line with advancements in service-delivery drones, and based on the theory of planned behaviour framework, this paper pioneers the discussion on consumers’ intention to accept their use based on their related perceived risks, potential functional benefits, and relational attributes, leading to a new type of relationship with the brand – namely, the customer–drone relationship. This discussion opens a new direction for retailers and academics alike to reflect on ...

In the present study, hydroxyapatite (HAp) and magnetic nanocomposite of HAp were used to recover and remove lead ions from an aqueous solution. For this purpose, chicken thighbone was used as the starting material. Lead ion adsorption was performed discontinuously within the temperature range 25–55℃, contact time 5–120 min, adsorbent dose 0.25–5 g/L, and pH 2–9. Under optimum conditions, the maximum lead ion adsorption efficiency was determined to be 93.75% and 96.11% by HAp and HAp/Fe3O4, respectively. FTIR, SEM, and EDS analyses were applied to characterize the adsorbents. Equilibrium data were studied using Langmuir, Freundlich, and D-R isotherm models. From the Freundlich constant and the determined isolation factor, it can be concluded that the adsorption process using both mentioned adsorbents is desirable and physical. Maximum lead adsorption capacity using HAp and HAp/Fe3O4 adsorbents was determined to be 105.26 mg/g and 109.89 mg/g, respectively, suggesting that these adsorbents have a satisfactory potential to adsorb lead ions. Thermodynamic investigation showed that the lead ion adsorption process is exothermic and spontaneous in both adsorbents, the degree of spontaneous adsorption process in the magnetic composite of HAp/Fe3O4 is higher, and the energy required for the adsorption process is less than that of HAp.
