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.

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.

Numerical studies on cold spray gas dynamics and powder flow in circular and rectangular nozzles

Journal of Manufacturing Processes
Cold Spray (CS) is an emerging metal additive manufacturing and surface coating technology, where metallic microscale powders are accelerated to supersonic velocities followed by impact onto a target substrate.

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.

Cold gas spraying of semiconductor coatings for the photooxidation of water

SPIE Proceedings, 2013
This contribution shows the potential of cold gas spraying for the production of photoelectrodes employing photoelectrocatalysts for the water oxidation reaction. Conventional methods of coating usually employ sol-gel methods and calcination to obtain a good binding of the coating to the substrate.
