Overview of cold spray coatings applications and comparisons: a critical review

Abstract

Purpose This paper aims to consolidate the results of various researchers focusing the different applications, so that this paper could become the torch bearer for the futuristic researchers working in the domain of cold gas dynamics spray coating. Design/methodology/approach A study on the cold spray coating is presented by summarizing the data present in literature. Important factors such as coating temperature, pressure, coating thickness, particle size, which affect the erosion-corrosion (E-C) resistance, physical and mechanical properties of boiler steel are stated. This paper also addresses the use of cold spray coating and compares it with other different thermal spray processes. Findings From the literature review, it was noticed that cold spray technology is best as compare to other thermal spray processes to reduce porosity, increase hardness, adhesion strength and retention in properties of feedstock powders. Originality/value Cold spray coating technology has a great potential in almost every field especially in restoration of surfaces, generation of complex surface, biomedical application, resist hot corrosion, wear, oxidation and erosion corrosion.

The Effect of the Substrate on the Microstructure and Tribological Properties of Cold Sprayed (Cr3C2-25(Ni20Cr))-(Ni-graphite) Cermet Coatings

“…Cermet coatings containing ceramic particles embedded in a metallic matrix meet criteria such as anti-wear, high hardness, and compact microstructure with good adhesion [ 1 , 2 , 3 , 4 ]. Protective Cr 3 C 2 -NiCr deposits are manufactured mainly using plasma spraying and HVOF; however, cold spraying is increasingly becoming popular [ 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. This type of coating has been deposited on various substrates, usually on low-carbon steel [ 5 , 6 , 7 , 8 ], corrosion-resistant steel, and aluminium alloys [ 21 ], depending on the application of the working element.…”

“…Cold sprayed deposits are produced by strong plastic deformation of the metal particles at a temperature below the melting point of the feedstock material. The metal powder particles undergo an adiabatic shear instability and form a coating by mechanical interlocking into the substrate [ 10 , 11 , 12 , 13 ]. Ceramic particles embed into a metal/alloy matrix.…”

Role of Artificial Intelligence in Distinct Sector: A Study

“…In addition, the major problems in thermal power plant are corrosion, oxidation and erosion. However, various authors [16][17][18][19][20][21][22][23][24][25][26][27][28][29] have used various types of coatings to combat high temperature oxidation, erosion corrosion. But, the use of AL in power plant can play a significant role.…”

Corrosion behavior of cold sprayed 7075Al composite coating reinforced with TiB2 nanoparticles

“…Surface treatment techniques such as cold spray (CS), along with other thermal spray processes, are commonly used for depositing a coating being protective of the metallic substrate material [1][2][3][4]. The principle of CS process is that feedstock powder particles are accelerated to supersonic velocity through a naval nozzle by highly compressed gas (e.g.…”
