Abstract

In this paper, low pressure cold spray process has been employed to produce coatings on three different substrates. The experiments have been designed using Taguchi L 18 array where the input parameters have been selected as the type of feed arrangement, substrate material, stagnation temperature, stagnation pressure of the compressed gas and stand-off distance. The effect of these key parameters on raw data and Signal to Noise (S/N) ratio for micro hardness of low pressure cold spray process has been studied. The coatings were successfully developed on the substrates and the micro hardness of the so produced coatings has been measured. The results show that a high value of micro hardness can be obtained by selecting the input parameters which increases the impact velocity of the striking particles. These high velocity impacting particles produces a peening effect to already attached powder particles thereby increasing the micro hardness of obtained coatings. It is seen that the significant process parameters are type of powder feeding arrangement, substrate material, stand-off distance stagnation pressure of carrier gas and stagnation temperature of the carrier gas.
