Microstructure, Mechanical Properties and Corrosion Behavior of the Aluminum Alloy Components Repaired by Cold Spray with Al-Based Powders

Metals, 2021
Aluminum alloy components of high-speed trains have a great risk of being corroded by various corrosive medium due to extremely complex atmospheric environments. This will bring out huge losses and reduce the safety and stability of trains.

Cold-Sprayed Metal Coatings with Nanostructure

Advances in Materials Science and Engineering, 2018
Cold spray is a solid-state coating deposition technology developed in the 1980s. In comparison with conventional thermal spray processes, cold spray can retain the original properties of feedstock, prevent the adverse influence on the underlying ...

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

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.
