Development of multimaterial coatings by cold spray and gas detonation spraying

Surface and Coatings Technology, 2010
Abstract The basic objective is the development of multifunctional multimaterial protective coatings using cold spraying (CS) and computer controlled detonation spraying (CCDS). As far as CS is concerned, the separate injection of each powder into different zones of the carrier gas stream is applied.

Particle-Substrate Interactions in Cold Gas Dynamic Spraying

International Thermal Spray Conference, 2003
Abstract Aluminium powder of 99.7wt% purity and in the nominal particle size range –75+15µm has been sprayed onto a range of substrates by cold gas dynamic spraying (cold spraying). The substrates examined include metals with a range of hardness, polymers and ceramics.

Localisation of deformation in cold gas dynamic spraying

Surface Engineering, 2016
One of the main specific features of the cold spray process is localisation during particle impact deformation. The resultant adiabatic shear instability is the phenomenon that is known to play a major role in the particle/substrate and particle/particle bonding and coating structure formation during the cold spray process.

Chemical Interaction and Bonding in Cold Gas Spraying

International Thermal Spray Conference, 2011
Abstract The effect of chemical interaction compared to mechanical influences on the bonding mechanism in cold-gas spraying is a matter of great interest. In this study, combinations of different metals (Al, Cu, steel) sprayed onto galvanized surfaces (Cr, Ni) will be used for a first approach to gain information about substrate-particle

Analysis of cold gas dynamically sprayed aluminium deposits

Materials Letters, 2004
Abstract Cold spray is a high rate, direct material deposition process that utilises the kinetic energy of particles sprayed at velocities in excess of 700 m s −1 to effect bonding through plastic deformation on impact. This paper describes the preliminary analysis of aluminium coatings deposited by this route.

Study on Process Optimization of Cold Gas Spraying

Journal of Thermal Spray Technology, 2010
Cold gas dynamic spraying is a relatively new spray coating technique capable of depositing a variety of materials without extensive heating. As a result the inherent degradation of the powder particles found during traditional thermal spraying can be avoided. The simplicity of this technique is its most salient feature.

Connecting Polymers and Metals Using Cold Gas Spray

AM&P Technical Articles, 2018
Abstract Coating development using cold gas spray technology demonstrates the feasibility of bonding polymers to metal substrates and metals to polymer composite substrates with good adhesion. The examples addressed are polyetheretherketone (PEEK) coatings on steel and aluminum substrates and metallic coatings on carbon fiber reinforced ...

Improved bonding strength of bioactive cermet Cold Gas Spray coatings

Materials Science and Engineering: C, 2014
The fabrication of cermet biocompatible coatings by means Cold Gas Spray (CGS) provides prosthesis with outstanding mechanical properties and the required composition for enhancing the bioactivity of prosthetic materials. In this study, hydroxyapatite/Titanium coatings were deposited by means of CGS technology onto titanium alloy substrates with the ...

Cold Gas Spraying of Lead-Free Bearing Bronzes

International Thermal Spray Conference, 2017
Abstract In current process techniques to manufacture sliding bearings, bronze components are soldered to the respective parts, which is cost and energy intensive. Apart from that, so far most bearing materials still contain lead, which in new applications is omitted by EU law to avoid associated health risks.

Influence of spraying parameters on cold gas spraying of iron aluminide intermetallics

Surface and Coatings Technology, 2015
Abstract Cold spraying was used to build up coatings of ordered Fe40Al intermetallics, which are a kind of alloys which are being proposed for high temperature applications. The spray experiments were performed with chemically ordered powder feedstock of different size distributions to study influences from impact velocities.
