OPTIMIZATION OF PROCESS PARAMETERS IN MULTILAYER EXPLOSIVE CLADDING USING TAGUCHI METHOD
Keywords:
Explosive cladding, Dissimilar metal, Optimization, Interlayer, Microstructure, Tensile strengthAbstract
In explosive cladding, an intense deformation resulting from high pressure and temperature emanating from a chemical explosive pack is used to join similar and dissimilar metals. The judicial selection of process parameters viz., explosive loading ratio, interlayer and preset angle is vital in achieving higher clad strength as the process is very rapid. Experiments were conducted based on three factor-three level L9 Taguchi design, to establish the significant process parameters and their optimum levels to obtain higher tensile strength in Aluminum-Stainless steel explosive clads using S/N ratio analysis. A mathematical model was developed to predict the tensile strength of clads using ANOVA. The influence of interfacial morphology on tensile strength of Al-SS304 explosive clads was reported with microstructural analysis. The proposed model can be effectively used to predict the tensile strength of Al-SS304 clads at 95% confidence level.
