Abstract

Shape memory alloys (SMAs), especially those based on Ni-Ti, have important applications in the medical field. Growing thin biodegradable polymer layers on the SMAs surface improves their corrosion resistance, biocompatibility and applicability as well. Using the pulsed laser deposition method, thin layers of biodegradable polymer PLLA (Poly-L-Lactide Acid) were deposited on nitinol substrates. They were subsequently studied by scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDX)..
