“…The increased coating hardness as well as the effect of third-body abrasion by ceramic particles may decrease the coefficient of friction (COF) significantly and reduce the wear rate by an order of magnitude. 22,94,119,160,213,214 as shown in Figure 27. 120,140 The decreased COF is becuase that the ceramic particles in the worn track change the wear mode from adhesion to abrasion.…”

“…95,181 The separated ceramic particles mix with the soft surface forming a strain-hardened layer, which protects the underlying coating and leads to the decreased wear rate. [213][214][215] Nevertheless, there are exceptions, for example, Triantou et al 216 reported that for CS Cu-A12O3, the COF increased with increasing the content of A12O3. However, the wear rate decreased because the plastically deformed Cu and its oxides formed a protective layer.…”

Cold spraying (CS) has been widely explored over the last decade due to its low process temperature and limited thermal effect on spray materials. As a solid-state process, the inherent deficiencies of traditional thermal spraying such as oxidation, decomposition and grain growth are avoided. This article summarizes the research work on the fabrication of composites and nanostructured coatings by the promising CS process. After a brief introduction to CS and its deposition mechanisms, the preparation methods of spray powders are classified. Different methods are appropriate for particles of various properties, and the tendency is to design composite powders by combined methods in order to create coatings with specified properties. Then the co-deposition mechanism of composite particles as well as research findings on metal-metal, metal-ceramic and metal-intermetallic composite coatings are reviewed concerning the deposition characteristics, microstructure and its relation to properties. Moreover, CS has been used to deposit a variety of nanostructured materials, including metals, metal-ceramic composites, and even ceramics, retaining their nanocrystalline nature in the coating without grain growth or phase transformation. Finally, the potential applications of CS and issues to be addressed in coating deposition are discussed.

“…There are generally two approaches for using cold spray to fabricate metal matrix composite coatings: (a) pretreatment powder processing such as cladding (Ref 12) and sintering (Ref [13][14][15][16][17], and (b) spraying mechanical blends of two or more powders (Ref [18][19][20][21][22][23][24][25]. For mechanically blended ceramic and metallic powders, previous researchers reported co-deposition of metallic particles with oxides and carbides.…”

Ni-WC composites are ideal protective coatings against wear and are often fabricated using laser cladding and thermal spray processes, but the high temperatures of these processes result in decarburization, which deteriorates the performance of the coating. Cold spray has the potential to deposit Ni-WC composite coatings and retain the composition of the initial WC feedstock. However, the insignificant plastic deformation of hard WC particles makes it difficult to build up a high WC content coating by cold spray. By using three different WC powder sizes, the effect of feedstock powder size on WC retention was tested. To improve WC retention, a WC/Ni composite powder in mixture with Ni was also sprayed. Microstructural characterization, including the deformed structure of Ni splats, retention, distribution, and fragmentation of WC, was performed by scanning electron microscopy. An improvement in WC retention was achieved using finer WC particles. Significant improvement in WC particles retention was achieved using WC/Ni composite powder, with the WC content in the coating being close to that of the feedstock.

“…For surfaces with low roughness, the first particles to impact would have little surface area available to which to bind, resulting in weaker bond strengths. These particles thus have a greater difficulty adhering to the substrate, resulting in an initial reduction of deposited mass [47].…”

Development of Sustainable Cold Spray Coatings and 3D Additive Manufacturing Components for Repair/Manufacturing Applications: A Critical Review

2017

View full text Add to dashboard Cite

This review article presents the findings of a comprehensive state-of-the-art literature review of the scientific and technological progress of the cold spray process in the field of repair/remanufacturing using the concept of additive manufacturing. A thorough study was conducted on the potential of this technology to form (a) both thin and thick coatings; (b) the ability to fabricate 3D freeform components in a single process, while benefiting from reduced residual stress level compared to conventional thermal spray coatings processes such as high velocity oxy-fuel (HVOF) or plasma spraying. A systematic overview of the process technology, particularly focusing on the suitability of ceramic-metallic (cermet) composite particles used as feedstock in the deposition was conducted; further elaboration was made pertinent to particle impact and bonding mechanisms during the deposition.
