OPTIMIZATION OF PROCESS PARAMETERS IN DISSIMILAR EXPLOSIVE CLADDING THROUGH TAGUCHI METHOD
Keywords:
Explosive cladding, dissimilar metals, Tensile strength, Taguchi approach, optimizationAbstract
Taguchi approach was employed to establish the significant process parameters viz., standoff distance, loading ratio and preset angle to enhance the tensile strength of aluminum-copper explosive clads. The experiments were conducted based on three factors, three-level Taguchi L9 orthogonal array. In addition, an empirical relation based on multiple regression analysis was developed to predict the tensile strength of Al-Cu explosive clads at 95% confidence level. The results indicate that standoff distance followed by loading ratio and preset angle has strong influence in achieving higher tensile strength of Al-Cu explosive clad. The microstructural characterization of Al-Cu explosive clads shows characteristic undulating interfaces.
