ANALISA PENGARUH VARIASI (% BERAT) MAGNESIUM DAN VARIASI TEMPERATUR OKSIDASI PADA PROSES ELECTROLESS PLATING ABU DASAR BATUBARA TERHADAP DENSITAS DAN POROSITAS BAHAN PROPELLER DARI KOMPOSIT ALUMINIUM – ABU DASAR BATUBARA

Abstract


The composite is a combination of two or more different materials on condition the bonding surface
between the two materials. One type of composites that much attention is metal matrix composites (KML). In this
study investigated how the influence of variations of Mg and temperature variations of oxidation on the density and
porosity of the composite amplifier undergo a process of electroless plating with variation (% by weight) of
magnesium 0,005, 0,010, and 0,015% and variations in temperature oxidation of 100, 200 and 300
C and at hold
for 3 hours, then made composite by Stir Casting casting method. Based on the average chart shows that increasing
the value of (% by weight) of magnesium and oxidation temperature
0
C the density values further down, This is
caused by the imbalance between the weight magnesium particles moistened (coal bottom ash) during the
electroless plating process. Based on the results of testing the value of the highest density achieved at a temperature
of 300
0
C to oxidation (wt%) 0.005 Mg is equal to 2.609 gr/cm
3
. And the value of the lowest density is achieved at a
temperature of 200

0
C to oxidation (wt%) Mg 0,010 is equal to 2.406 g / cm
Keywords: composite, electroless plating, stir casting, density-porosity.
