Design of Experiment (DOE) Study of Hydroxyapatite-Coated Magnesium by Cold Spray Deposition

Abstract:

In this study, hydroxyapatite powder was sprayed onto pure magnesium plate using a simple modified cold spray process. The effects of process parameters (i.e.standoff distance, surface roughness, substrate, substrate heating temperature and number of spray) were studied using 2^k-1 factorial design.Analysis of variant (ANOVA) were used to determine the significant of process parameters on the coating. Thickness of coating, nanohardness and elastic modulus were chosen as the responses for assessing the most significant parameters that affected the hydroxyapatite coated onto pure magnesium plate. HAP particles have found to be bonded well in sample of run 11 while sample of run 4 show poor bonding between HAP particles and magnesium substrate. The effect of individual variables on the response was briefly discussed.
