Basic principles and application potentials of cold gas spraying

Materialwissenschaft und Werkstofftechnik, 2010
AbstractCold spraying is a well‐established coating technology for several materials and applications. The formation of dense microstructures occurs only by the plastic deformation of particles hitting the substrate with sufficiently high kinetic energies.

Calibration of the Critical Velocity in Cold Gas Spraying

International Thermal Spray Conference
Abstract In cold gas spraying, successful bonding occurs when particle impact velocities exceed the critical velocity. The critical velocity formula depends on material properties and temperature upon impact, relying mainly on tabulated data of bulk material.

Deformation and Adherence of Fe40Al Particles in Cold Gas Spraying

International Thermal Spray Conference, 2013
Abstract This study investigates the impact behavior and consequences for coating formation in cold spraying of FeAl intermetallic compound powder. A range of spraying conditions was used to process single impacts in so-called wipe tests and for processing spray layers. In order to avoid brittle failure, high process gas temperatures and

Study of stellite-6 deposition by cold gas spraying

Surface and Coatings Technology, 2013
Abstract Cold gas spraying (CGS) has been used to generate coatings using ductile materials which are easily deformed with the impact generated by the high kinetic energy of the process. The deposition of less ductile materials is being a challenge.

Potential of Cold Gas Spraying in Power Electronic Applications

International Thermal Spray Conference, 2010
Abstract A successful combination of isolating substrates with conducting metal coatings produced by cold spraying could open new industrial application areas like the fabrication of power electronic components. For minimizing the number of industrial process steps, isolating ceramic layers should ideally be processed by thermal spray ...

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.

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 ...

Production of Titanium Deposits by Cold Gas Dynamic Spray

International Thermal Spray Conference, 2005
Abstract Over the past five years, interest in cold gas dynamic spraying (CGDS) has increased substantially. Considerable effort has been devoted to process development and optimization for low melting point metals such as copper and aluminium. This paper will describe work undertaken to expand the understanding of deposition of titanium
