STUDI ANTAR MUKA TOP COAT DAN BOND COAT PADA REKAYASA PELAPISAN ALUMINA SEBAGAI LAPISAN PERINTANG PANAS UNTUK APLIKASI TEMPERATUR TINGGI
Abstract: This research
summarized the microstructure analysis of interface Top coat Al2O3 and Bond
coat NiAl alloy which deposited to substrate AlSi alloy by use of PFS Powder Flame
Spraying) technique, and
thermal cyclic where
the out put specimen
from fleme spraying
is brought to
the boil inside the
furnace at temperatrure 600oC
with several cycles at 20, 50, and 100, and each cycle is held a weighing.
For testing phase
and microstructure is using
the XRD, SEM (Scanning Electron Microscopes) and EDS
(Energy Dispersive Spectrometer). In order to find out the hardness which it
forms at each layer and interface is using the microhardness tester. This
research has a scertainable, thet the bond which is formed at interface has a
high hardness where is thermal cyclic had an effect on TGO figuration
and varying phase.
The TGO figuration,
as affect of
thermal cyclic, cause a reduction of the bondcoat it formeda
microporosity which is made a failure at TBC system.
