Tribological Behavior of a Cold-Sprayed Cu–MoS 2 Composite Coating During Dry Sliding Wear
TL;DR: In this article, two cold spray coatings, one pure Cu and the other a Cu-MoS2 composite coating, were studied for their tribology performance in dry air, and it was demonstrated that a small amount of MoS2 (1.8± 0.99 ǫ) could significantly decrease coefficient of friction (CoF) from around 0.7 (Cu coating) to 0.14-0.15.

Computational analysis of the interfacial bonding between feed-powder particles and the substrate in the cold-gas dynamic-spray process
TL;DR: In this paper, the cold-gas dynamic-spray process is analyzed by numerical modeling of the impact between a single spherical feed-powder particle and a semi-infinite substrate and the results obtained indicate that the two main factors contributing to the observed higher deposition efficiency in the case of copper deposition on aluminum are larger particle/substrate interfacial area and higher contact pressures.

Adhesion and Durability of Metal/Polymer Bonds
TL;DR: A review of the factors responsible for the integrity and long-term durability of metal-polymer bonds used in the fabrication of aircraft and aerospace structures is presented in this paper, where it has been determined that the initial integrity of metal polymer bonds depends critically upon the morphology of the surface oxide on the metal.
