Your goal is to use the continous casting method to create a metal matrix composite. You have chosen
graphite as the reinforcement material and Al-alloy as your metal matrix. To the variations in densities
between the reinforcing material and matrix, a coating application needed on graphite's surface. The
densities of the materials follow:
Matrix:
Al=2165kgm3
Reinforcement:
graphite=2.23gcm3
Coating:
Ni=8946kgm3
Al-alloy contains 7.55 wt.% Si,0.16 wt.% Mg,1.54 wt.% Cu, and rest Al. The particles of graphite are
non-porous and spherical structures. The average particle size (diameter) of graphite is 85m
In a crucible, the continous casting procedure will be carried out at 750C. You want to melt 13lbmAl-
alloy and add 1.6 wt.% reinforcement material.
During the coating process, a 1/3 solid-to-liquid ratio (i.e.,1kg solid to 3L liquid) with a solution of 0.65pH
will be used. The Ni source of the coating process is NiSO4, and 13% excess Ni will be used. H2SO4
solution (95%ww and 1.83gcm3 density) will be added to adjust pH, and the rest will be pure H2O
(density 1.0gcm3).
Calculate:
a) amount of graphite (g) added to the solution,
b) amount of NiSO4(g) added to the solution,
c) amount of H2SO4 solution (cm3 or L) in the solution,
d) amount of pure or {:L) in the solution,
e) the average thickness of the Ni coating (m) coated on h-BN,
f) the Ni content (wt.%) after the slip casting process.
