“…Cold spray (CS) belongs to a wide family of thermal spray technology with the difference that CS is a solid state process in which spray particles are deposited via supersonic velocity impact at a temperature much below the melting point of the spray material [1]. Cold spray has been applied for deposition of a wide range of materials for industrial protective wear coatings of components such as those used in automobile, power plant, and aerospace.…”

Carbon nanotube reinforced alumina matrix nanocomposite was fabricated by cold spray process on Al-Si alloys surfaces. The effects of various amounts of CNTs from 0, 2 and 4 wt % on alumina powders were investigated. Results show that the improvement in both wear resistance and hardness was provided by 2 wt. % CNTs reinforcement. The hardness of carbon nanotube reinforced alumina matrix nanocomposite was increased due to an enhanced load sharing of homogeneously distributed carbon nanotubes. Homogeneous distribution of CNTs within the Al 2 O 3 matrix and strong interfacial connection between CNTs-Al 2 O 3 give nanocomposites with superior wear properties.

“…This is basically due to their low density, excellent oxidation resistance, hot corrosion resistance, high specific strength and low ductile to brittle transition temperature [1,2]. Their application is, however, limited by their low ductility, poor creep resistance [3] and low wear resistance [4]. It has been shown that the incorporation of ceramic particles into iron aluminide matrix improves its tribological properties [5,6].…”

Adding TiC particles into iron aluminide coatings has been found to improve its wear resistance, but its corrosion behavior is less known. In this study, the corrosion behavior of Fe3Al/TiC and Fe3Al-Cr/TiC composite coatings, prepared by high velocity oxy fuel (HVOF) spraying, was studied in 3.5 wt. % NaCl solution by means of electrochemical techniques and surface analysis. Results revealed that adding TiC particles into Fe3Al matrix to improve the wear resistance does not deteriorate the corrosion behavior of Fe3Al coating. It was also showed that addition of chromium to Fe3Al/TiC composite provides a more protective layer.

“…A basic procedure was conducted to apply the metal spray to a concrete structure for water treatment. Figure 1 shows that the arc thermal spraying process using the coating was applied on the concrete surface with a circular slit of hot and compressed air [20,21]. Four kinds of metal sprays were selected, and their ozone resistance was evaluated.…”

Abstract:We evaluated the applicability of metal spray coating as a waterproofing/corrosion protection method for a concrete structure used for water purification. We carried out an ozone resistance test on four metal sprays and evaluated the water permeability and bond strength of the metals with superior ozone resistance, depending on the surface treatment method. In the ozone resistance test, four metal sprays and an existing ozone-proof paint were considered. In the experiment on the water permeability and bond strength depending on the surface treatment method, the methods of no treatment, surface polishing, and two types of pore sealing agents were considered. The results showed that the sprayed titanium had the best ozone resistance. Applying a pore sealing agent provided the best adhesion performance, of about 3.2 MPa. Applying a pore sealing agent also provided the best waterproofing performance. Scanning electron microscope analysis showed that applying a pore sealing agent resulted in an excellent waterproofing performance because a coating film formed on top of the metal spray coating. Thus, when using a metal spray as waterproofing/corrosion protection for a water treatment concrete structure, applying a pore sealing agent on top of a film formed by spraying titanium was concluded to be the most appropriate method.
