Bonding behavior studies of cold sprayed copper coating on the PVC polymer substrate

A Review of Thermal Spray Metallization of Polymer-Based Structures

“…3, the metal coating and the granular particles used for roughening the polymer-based substrate are bound by mechanical interlocking. On the other hand, the deposition of thermally sprayed coatings onto polymer-based substrates without surface preparation has also been reported in the literature ( Ref 21,25,40,47,68). In cold spraying, the sprayed particles were heated to temperatures below the melting temperature of the powder material.…”

“…Thermal spray deposition of metal particles onto polymer-based structures has gained increasing attention through studies on the metallization of fiber-reinforced polymer composite (FRPC) (Ref [15][16][17][18][19][20], polymer matrix composite (PMC) ( Ref 21,22), and neat polymer substrates (Ref [23][24][25][26][27][28]. Polymer-based materials, such as PMC structures, can provide enhanced mechanical properties (i.e., high specific strength and high specific stiffness) with respect to single-phase (i.e., metallic) structures.…”

Ternary Cu–CNT–AlN composite coatings consolidated by cold spray deposition of mechanically alloyed powders

“…However, when the particles are not deposited and are simply rebounded, they have grit blasting and shot peening effects that respectively result in erosion and compaction of the substrate and the deposited layer [47,48]. Thus, it can be viewed that the CGDS process is a triplex process, which involves grit blasting, coating deposition, and shot peening [49].…”

Degradation by Other Forms of Radiation

“…Samples were irradiated at a constant fluence of 2.25x10 9 ions cm -2 with varying energies (25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37) and at a constant energy (25 MeV) with varying fluence from 2.25x10 9 to 1.0x10 15 ions cm -2 . Samples were irradiated at a constant fluence of 2.25x10 9 ions cm -2 with varying energies (25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37) and at a constant energy (25 MeV) with varying fluence from 2.25x10 9 to 1.0x10 15 ions cm -2 .…”

“…24 Physical vapor deposition of Fe, Ni, Cu, Ag, and Au on PVC has been studied. 25 The electrical conductivity of the coating is fairly low due to the pores and inter-particle defects. For metals with more than one stable oxidation state, the salt produced corresponded to the metal's lowest stable oxidation state (e.g., CuCl instead of CuCl 2 ).…”
