Cold spray (CS) technique is a process whereby metallic particles are utilized to form coatings using ballistic impact upon substrate materials. This technique is based on the high velocity (3001500 m/s) impinging of small solid particle (generally 1050 mm in diameter) on substrates. In this process, the particles are accelerated by the supersonic gas jet at the heated gas temperature, which is usually lower than melting temperature of powder materials. Consequently, this process solved the problem of thermal spraying, such as high temperature oxidation, phase transformation etc. Until now, the CS has a good track record in almost metallic coatings, such as copper, stainless steels, Ni base superalloys etc. Recently, some kinds of ceramics and polymers can be coated by the CS. The CS is expected as not only coating technique but also thick ˆlm formative technique. In this article, the present situation and future prospects of the CS are explained.

A stackable Knudsen pump consisting of multistage pump units driven by temperature diŠerence between hot and cold water is fabricated. Each unit has a porous membrane of 64 cm2 area, through which thermal transpiration ‰ow, the driving force of the Knudsen pump, is induced at atmospheric ambient pressure. This study demonstrates the present device facilitates the cascade or parallel connection of multiple pump units to improve performance. For example, a Knudsen pump consisting of 6cascaded units provides a shut-oŠ pressure of 9.2 kPa and a 300 sccm maximum ‰ow rate at the temperature diŠerence of 45 K. The feasibility of the pumping system driven by low-grade waste heats is also demonstrated.
