Iron-based coatings arc-sprayed with cored wires for applications at elevated temperatures

New Technological Concept for Thermal Spray Protective Coatings

“…The choice of materials and coatings for use in specific conditions should include [1][2][3][4]: -identifying the types and factors causing wear; -defining the requirements of the substrate material (chemical composition, temperature applications, the surface condition and so on); -definition of tasks and technical requirements for the coating (cost, maximum wear, and the like). In turn, the factors determining the choice of technology applying surface layers are, e.g.…”

“…In turn, the factors determining the choice of technology applying surface layers are, e.g. [1][2][3][4]: -the possibility of given type material application and produce the desired structure of the chosen technology; -type of the element and protected area as well as the shape of protected elements; -the efficiency and economy of the process -the production time of coatings and material, energy consumption, real cost; -qualifications and experience of persons performing protection.…”

“…Influence of the spraying technology on the protective properties of the coatings has been the subject of many studies [1][2][3][4][5][6]. Generally we can say, that the resistance of coatings to complex corrosion-erosion wear conditions resulted primarily from the chemical composition of the coating and its structure (Fig.…”

“…1). The structure was determined by the type of technology used spraying [1][2][3][4][5][6]. The coatings with a homogeneous fine dispersive morphology structure and low porosity have got improved protective properties.…”

“…The presented idea of new hybrid spraying method is part of this trend. In this paper, the presented method and selected results are only reconnaissance research and be continued in research project [1][2][3][4][5][6][7].…”
