How Cold is Cold Spray? An Experimental Study of the Heat Transfer to the Substrate in Cold Gas Dynamic Spraying

International Thermal Spray Conference, 2008
Abstract Time-resolved thermographic measurements were performed by a high speed infrared camera on a substrate surface during cold gas dynamic spraying without powder particles. Experiments were carried out on three commercial cold spray systems (Centerline SST, CGT Kinetiks 3000 and Inovati KM-CDS 2.2) spanning a wide range of gas ...

Numerical Simulation of the Cold Gas Dynamic Spray Process

Journal of Thermal Spray Technology, 2006
Abstract A computational fluid dynamic (CFD) model of the cold gas dynamic spray process is presented. The gas dynamic flow field and particle trajectories within an oval shaped supersonic nozzle as well as in the immediate surroundings of the nozzle exit, before and after the impact with the target plane, are simulated. Predicted nozzle

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.

CoNiCrAlY microstructural changes induced during Cold Gas Dynamic Spraying

Surface and Coatings Technology, 2008
The present study is part of an ongoing research project that aims to develop high performance bond coats by means of Cold Gas Dynamic Spraying (CGDS) for the manufacturing of thermal barrier coatings (TBC). The objective of this work is to investigate the microstructure of a CGDS coating and compare it to that of the original feedstock powder in order

Computational Simulation for Gas Heater of Cold Spray System

International Thermal Spray Conference, 2013
Abstract This paper demonstrates the use of commercial simulation software to evaluate a new heater design for cold gas spraying. The gas heater consists of a heating unit and a self-cooling housing. The heating unit is a coiled tube encased in an insulating enclosure.

Pulsed-Cold Gas Dynamic Spraying Process: Development and Capabilities

International Thermal Spray Conference, 2007
Abstract A new process, the Pulsed-Cold Gas Dynamic Spraying process is presented in this work. A description of the process and of the experimental set-up developed at the University of Ottawa Cold Spray Laboratory is presented. It is envisioned that this process could allow for the feedstock particles to be accelerated to high impact ...

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

Cold gas spray titanium coatings onto a biocompatible polymer

Materials Letters, 2013
Abstract Titanium particles were deposited onto Polyetheretherketone substrates using Cold Gas Spray technology and a factorial number of experiments were designed in order to study different spraying conditions. The starting powder and the obtained coatings were characterized with the aim of linking the results with the coating process.

Deposition Mechanisms of Cold Gas Dynamic Sprayed MCrAIY Coatings

International Thermal Spray Conference, 2007
Abstract Thermal-sprayed (i.e. LPPS or HVOF) MCrAlY coatings are widely used for land-based gas turbine applications against high-temperature oxidation and hot corrosion. However, due to requirement for further improvement of turbine efficiency, dense and stable coatings are necessary. The cold spray (also referred to as cold gas dynamic
