Description |
Two body abrasive wear behaviour of a zinc-aluminium alloy - 10% Al2O3 composite was
studied at different loads (1–7 N) and abrasive sizes (20–275 ¹m) as a function of sliding
distance and compared with the matrix alloy. The wear rate of the composite and the
matrix alloy has been expressed in terms of the applied load, abrasive size and sliding
distance using linear factorial design approach. The study suggests that the wear rate of
the alloy and composite follow the following relations:
Yalloy D 0:1334¡0:0336x1 C0:0907x2 C0:0219x3 ¡0:0296x1x2 C0:0274x2x3 ¡0:0106x3x1
¡0:0201x1x2x3
Ycomp D 0:0726¡0:028x1 C0:062x2 C0:03x3 ¡0:024x1x2 C0:028x2x3 ¡0:016x3x1
¡0:014x1x2x3
where, x1, x2 and x3 are the coded values of sliding distance, applied load and abrasive size
respectively. It has been demonstrated through the above equations that the wear rate
increases with applied load and abrasive size but decreases with sliding distance. The
interaction effect of the variables exhibited a mixed behaviour towards the wear of the
material. It was also noted that the effect of load is less prominent for the composite than
the matrix alloy while the trend reversed as far as the influence of the abrasive size is
concerned.
