This report provides an overview of cold spray (CS) technology as it relates to repair and fabrication of metal alloys in the nuclear power industry. CS is a relatively new technology with applications established in other industries (i.e., aerospace, defense), and its greater utilization is anticipated within the nuclear power industry. The purpose of the overview is two folds. First, it is an attempt to familiarize readers with the merits and limitations of CS technology, and its process parameters, so that readers understand the technical justifications for a CS application and chosen CS process parameters. Secondly, it endeavors to facilitate understanding CS as a potential technology for emerging nuclear power applications.
A high-level overview of CS technology and its history is provided in the remainder of this section, while Section ?2.0 provides a more detailed overview of CS technology, including equipment, process parameters and control, and coating properties. Section ?3.0 includes a summary of current studies and applications of CS technology, and Section ?4.0 describes knowledge gaps and technical challenges associated with the utilization of CS in the nuclear power industry.
