Particle-particle interface corrosion of cold sprayed copper in dilute nitric acid solution: Geometry-controlled corrosion mechanism

By Xuejie Li and others at
LogoUniversity of Western Ontario
The mechanism of particle-particle interface (PPI) corrosion observed in cold sprayed (CS) Cu immersed in dilute HNO3 has been elucidated. PPI corrosion is initiated by the oxide inclusions present along the PPIs. The accelerated corrosion rate at PPIs results from the combined effects of confined geometry and catalytic reactions, which... Show more
