Abstract

The dry sliding wear behavior of AA6061/ZrB ₂ in-situ composite prepared by the reaction of inorganic salts K ₂ZrF ₆ and KBF ₄ with molten aluminum was investigated. An attempt was made to develop a mathematical model to predict the wear rate of AA6061/(0-10) ZrB ₂ in-situ composites. Four-factor, five-level central composite rotatable design was used to minimize the number of experiments. The factors considered are sliding velocity, sliding distance, normal load and mass fraction of ZrB ₂ particles. The effect of these factors on the wear rate of the fabricated composite was analyzed and the predicted trends were discussed by observing the wear surface morphologies. The in-situ formed ZrB ₂ particles enhance the wear performance of the composite. The wear rate of the composite bears a proportional relationship with the sliding velocity, sliding distance and normal load.
