Coating by the Cold Spray Process: a state of the art

Fracture and Structural Integrity, 2013
A brief description of cold spray coating process is presented. This paper intends to review some the previous works which are mostly about the influences of the cold spray parameters, mostly the surface of the substrate, on the deposition efficiency (DE)

Spark plasma sintering treatment of cold sprayed materials for synthesis and structural modification: A case study using TiC-Cu composites

Materials Letters: X, 2022
Materials obtained by cold spraying (CS) are subjected to post-spray treatment to increase cohesion between the particles. In this work, spark plasma sintering (SPS) was used for reactive processing of cold spray deposits for the first time. A mixture of

Post-Processing of Cold Sprayed CoNiCrAlY Coatings on Inconel 718 by Rapid Induction Heating

Metals, 2022
Cold spray is a solid-state additive manufacturing process that has been increasingly used for restoration of damaged parts. Due to the nature of powder solid-state bonding, cold spray coatings usually possess pores in the microstructures. Heat treatment

Study of in-flight and impact dynamics of non-spherical particles from HVOF guns [PDF]

, 2009
High velocity oxygen fuel thermal spray has been widely used to deposit hard composite materials such as WC-Co powders for wear-resistant applications. Unlike gas atomized spherical powders, WC-CO powders form a more complex geometry.

Cold Spray Coatings Morphology [PDF]

Archives of Metallurgy and Materials
In the Cold Spraying technology, the coatings are produced as a result of the supersonic acceleration of the particles in a gas jet, at temperatures below the melting/phase transformation point of the sprayed material.

Effects of Traverse Scanning Speed of Spray Nozzle on the Microstructure and Mechanical Properties of Cold-Sprayed Ti6Al4V Coatings [PDF]

, 2017
Cold spray has the potential to restore damaged aerospace components made from titanium alloy, Ti6Al4V at low temperature (200-400 °C). Traverse scanning speed during deposition is one of the key factors that affect the quality of the Ti6Al4V coatings as
