klar tek tek zml bir ekilde yapabilir misin ?
You want to apply a coating via a metallothermic reduction. The substrate material is a steel alloy containing
0.16 wt.% C,1.3 wt.% Si,1.0 wt.%Mn,8.9 wt.% Cr,5.1 wt.%Ni, and the rest Fe. The substrate is
cylindrical with a 11.9cm diameter and 5.3cm height.
The coating material is a nickel-based superalloy with a targeted composition of 21.0wt%Cr,10.0wt.%
Fe,5.9wt%Nb,5.3wt%Ti,3.6wt%Mo,1.1wt%Co, and rest Ni. To produce this superalloy, you will
use a metal-oxide mixture ) and metallic Al powder.
Your goal is to produce a 5.6mm average coating layer onto the top surface of the steel substrate.
a) Calculate the amount of the raw materials to obtain the mentioned coating layer (g of compounds).
b) Calculate the adiabatic temperature of the metallothermic reaction while assuming all the mixtures are at
room temperature or K).
If the reduction efficiencies of the metals follow: 91%Ni,89%Cr,90%Fe,53%Nb,36%Ti,71%
Mo,89%Co; the unreacted Al passes into the superalloy; unreacted metal oxides pass into the slag:
c) Calculate the final composition of the coating layer (wt.% of elements).
d) Calculate the average height of the coating layer (mm).
e) Calculate the amount of the slag (g).
f) Calculate the composition of the slag (wt.% of oxides).
g) Calculate the final temperature of the substrate (initially 25C) that coated with Ni-superalloy or K).
steel=
[7884-190.4(wt.%C)-150.5(wt.%Si)-4.7(wt.%Mn)-7.2(wt.%Cr)+7.3(wt.%Ni)-0.30t(C)]kgm3
Ni-alloy=
[(8.9%Ni)+(7.2%Cr)+(7.9%Fe)+(8.4%Nb)+(4.5%Ti)+(10.2%Mo)+(8.9%Co)+(2.7%Al)]100gcm3
