In this issue, the effect of gas heat treatment ambient at the temperature of 950C
for 8hours using the gases NH3 or CH4 and using the gases NH3 and CH4 for
(4+4)hours of the distribution of the doping elements on Titanium alloys BT9 was
studied.
Oxide formation at the different treatment ambient as a reason of gas-phase
oxygen distribution to high depths in the samples was discovered.
This paper provides a mechanism to study aluminum diffusion microstructure, phase
structure and different properties of the aluminized layer in carbon steel.
The results of aluminized treatment in saturated medium lead to the formation of diffusion
layer coating that contains iron aluminide and a- solid solution of aluminum in the unit cell of
iron.
The effect of aluminizing process parameters on the aluminizing layer, especially the
effect of temperature and time, has been shown to increase the depth of the aluminized layer
when temperature and time increase, but the effect of temperature is greater than time.
