“…Measurements showed that the coated films before and after the photocatalytic experiment (under optimum condition) have an actual adhesion of 3.2 and 2.74 MPa, respectively. These values are essentially high considering the thickness of the coatings . A decrease in this property may be related to centrifugal force created by the spinning action which weakens the interface adhesion.…”

A spinning disc photoreactor using immobilized TiO 2 on a stainless steel disc is employed to study the degradation of phenol in aqueous solutions. The characterizations of the immobilized TiO 2 film are carried out by scanning electron microscopy, field emission scanning electron microscopy, X-ray diffraction, Brunauer−Emmett−Teller analysis, and tensile adhesion test. The Box−Behnken design method is employed to identify the effects of three key operational parameters. The maximum predicted nanophotocatalytic degradation percent of phenol was 100% at the optimum processing condition (rotational speed, 290 rpm; flow rate, 2000 mL/min; and disc diameter, 22 cm). For a description of the flow pattern, the residence time distribution analysis is performed. By using a tanks-in-series model the equivalent number of continuous stirred tanks reactors at the obtained optimum condition was four. Hydrodynamic and kinetic models were combined to predict the degradation of phenol. Good agreement between the experimental and predicted results is shown.

“…Donadei et al [22] have noticed that lower process temperature by using high transverse speed and higher working distance will cause less polymer degradation during spraying, which is beneficial for icephobic behavior of the coatings. The advantages of thermally sprayed polymer coatings are related to the low cost and high performance of the coatings [3,25]. Flame-sprayed polyethylene (PE) coatings have previously been studied by Vuoristo et al [26], where the research focused on the use of flame-sprayed PE coatings as natural gas pipeline coatings.…”

Thermally Sprayed Coatings: Novel Surface Engineering Strategy Towards Icephobic Solutions

Surface engineering promotes possibilities to develop sustainable solutions to icing challenges. Durable icephobic solutions are under high interest because the functionality of many surfaces can be limited both over time and in icing conditions. To solve this, one potential approach is to use thermally sprayed polymer or composite coatings with multifunctional properties as a novel surface design method. In thermal spraying, coating materials and structures can be tailored in order to achieve different surface properties, e.g., wetting performance, roughness and protection against several weathering and wearing conditions. These, in turn, are beneficial for excellent icephobic performance and surface durability. The icephobicity of several different surfaces are tested in our icing wind tunnel (IWiT). Here, mixed-glaze ice is accreted from supercooled water droplets and the ice adhesion is measured using a centrifugal adhesion tester (CAT). The present study focuses on the icephobicity of thermally sprayed coatings. In addition, surface-related properties are evaluated in order to illustrate the correlation between the icephobic performance and the surface properties of differently tailored thermally sprayed coatings as well as compared those to other coatings and surfaces.

“…The flame spray polymer coatings can be applied in several industrial fields as aviation, marine, metal manufacturing, pump, chemical, petrochemical, energy and automotive industries. Successful deposition of polymer coatings by flame spraying involves careful consideration of polymeric material limitations and the capabilities of individual spraying process [6][7][8][9][10][11][12][13][14][15][16][17].…”

Flame spraying of polymers allows obtaining functional coatings for protecting against wear and corrosion. Among many engineering polymers, the Ethylene-Vinyl Acetate (EVA) copolymer attracts attention with its superior mechanical and chemical properties. EVA, which has high chemical resistance, high impact resistance and mechanical flexibility, high friction coefficient, is among the candidate coating material that can be used in aerospace, automotive, marine, chemical and manufacturing industries to protect metallic surfaces. The use of polymeric coatings in applications is often restricted when large surfaces need to be coated or if the coating needs to be applied in the openair field. Flame spraying is one of the most cost-effective methods in the production of polymeric coatings. The curing process and solvent use required in conventional polymeric coating applications are not required in thermal spray coating applications. Contact of polymeric surfaces with solid surfaces and abrasive solid particles reduces polymer life and performance. In this study, solid particle wear behaviors of EVA coatings on stainless steel produced by flame spraying is investigated and then tested in different erosive wear test conditions. The erosive wear rates were compared with stainless steel. The main wear mechanism in the polymeric coatings is associated with micro-deformation, micro-cratering and micro-crack formation.
