Commercial Cold Spray Equipment

Abstract

Two variants of cold spray powder injection point (downstream and upstream) came about from two distinct development threads in Russia; These two groups produced two distinct families of commercial equipment, each one with its own unique merits and attributes. Based on these concepts, commercial cold spray equipment became available in the late 1990s with several machine suppliers, some of them already gone, whereas others became established. This chapter is an update to the latest commercially deployed equipment, keeping in mind that the rapid evolution of cold spray technology may likely result in availability of additional upgrades by the time of publication. This Chapter discusses machine design features of each one of the families which determines capacity, reliability, portability, and cost. As every cold spray application requires a unique set of conditions, for it to be commercially viable, each type of equipment offers advantages and disadvantages in relation to an application; therefore, proper equipment selection is always the best practice.
