Abstract:
The area of biomedical materials acts a significant role in manufacturing of a
variety of biological artificial replacements which are very common in the modern
times. At present time nitinol alloy is an engineering material used in the medical
industry. Laser surface processing has been looked as a promising method to
promote surface properties of materials without changing or affecting bulk
properties in multiple applications. Pulsed laser deposition characterizes by high
instantaneous deposition rate and thin film with low impurity incorporation. The
aim of this work is characterizing the morphological properties and surface
roughness of nitinol alloy due to the deposition of thin film of carbon. Carbon film
shows corrosion resistance and chemical inertness at various applications in
metallurgy, surface finishing and semiconductors. The maximum amount of carbon
in weight percent is 13.805%and maximum roughness is 17.7nm at the room
temperature , 1064nm,800mJ and 250 pulses. The best roughness is 0.902nm at
100? ,532nm,200mJ and 300 pulses.
