The College of Dentistry at the University of Basrah participated in discussing a doctoral thesis entitled "Corrosion inhibitors for dental alloys by laser surface treatment and coating of zinc oxide and aluminum oxide nanoparticles using pulsed laser deposition technology."
The discussion was conducted with the participation of Assistant Professor Dr. Rafid Mustafa Badr, a lecturer at the College of Dentistry, as a member of the discussion committee for the doctoral thesis of researcher Sarah Abbas Jassim.
The thesis dealt with the effect of laser surface melting treatment (LSP) on the corrosion behavior of dental alloys in an artificial saliva medium with an acidity concentration (PH = 5.6).
The study showed the effect of laser surface melting treatment parameters, such as laser energy and pulse number, on microhardness, surface roughness, and corrosion resistance. Experimental results showed that surface roughness increases and leads to an increase in microhardness near the surface of the samples.
