Effects of DPV-2000 Software Parameters on the Measurement of In-flight Particles in Cold Spray

摘要

Cold spray is a relatively recent coating technology, where coating can be formed only when the velocity of in-flight particles exceeds critical velocity Therefore, velocity is a key factor in cold spray [1]. DPV-2000 system has been used to detect velocity, temperature and diameter of in-flight particles in thermal spray, but few studies have been reported on the measurement of velocity and diameter with DPV-2000 in cold spray [2-3]. The effects of the software parameters are discussed in this paper to clarify how the parameters affect the measured results of velocity and diameter in cold spray.
