A work team from the Production Engineering and Metallurgy Department obtains a patent in deposition of titanium on steel using nanotechnology for direct deposition (hot metal threads) in the oil sector

All of Dr. Amin Dawai Thamer, a former faculty member in the Production Engineering and Metallurgy Department, and Dr. Bahaa Sami Mahdi, a faculty member in the Production Engineering and Metallurgy Department / Metallurgy Engineering Branch, and their doctoral student, Na'am Fawzi Muhammad Ali, obtained a patent for titanium deposition on steel using nanotechnology for direct deposition (hot metal threads) in the oil sector. The direct deposition method is a new and highly efficient method for precipitating titanium in particular compared to all other methods represented by direct current sputtering deposition or even using the frequency and high voltage atomization deposition method using magnetic field.

In short, the direct deposition method is the cheapest and simplest method for depositing the hardest metal on solid surfaces. The method simply includes heating the titanium thread to a temperature ranging from 900 to 1200 degrees Celsius inside a highly vacuumed glass chamber (1X10-4mbar) and when degassing using a rotary pump only. Discharging takes place in two steps, the first is the degassing and then the introduction of the Arcon gas, and the second includes the discharge of the Arcon gas to ensure that there is no oxygen, which will be very harmful to the process. When the temperature reaches the required degree, the titanium atoms are directly transferred from the thread by sublimation and adhesion to any adjacent surface without the need to reach the liquid state and at a sedimentation speed no less than six times faster than the most powerful devices for direct current spraying.
