Theory and Technology of Sintering, Heat Treatment, and Chemicothermal Treatment


Healing a quartz substrate in a medium of IPC to a temperature above 500 K. by pulsed (> 5·10−1 sec) radiation of a CO2 laser with intensity of 50–100 W·cm−2 yields thin (up to 3 μm) iron films at a rate of 2 μm·sec−1 on a surface bounded by the cross section of the laser beam.

When the intensity of the radiation is increased to 250 W·cm−2, the process of decomposition of the IPC spreads to the gaseous phase. Together with intense crystallization of iron on the surface of the substrate (the surface temperature is ∼ 1500 K) a finely disperse (0.1–0.3 μm) iron powder also forms.
