Machining the Surface of Orthopedic Stent Wire Using a Non-Toxic Abrasive Compound in a Magnetic Abrasive Finishing Process

The orthopedic stent wire is one of the critical medical components, which mainly used for replacement physically damaged parts in human body. Therefore, a smooth surface and lack toxic substances on this component are highly demanded. In study, magnetic abrasive finishing (MAF) process was carried out using non-toxic compound (a mixture iron powder, diamond particles, cold cream, eco-friendly oils) to achieve high-quality wire. roughness (Ra) investigated according various processing parameters: different rotational speeds (500, 1000, 2000 rpm), particle sizes (1.0 µm), three oils (olive oil: C98H184O10; grapeseed C18H32O2; castor C57H104O9) within 300 s time. results showed that reduced 0.04 µm with rotation speed 1000 rpm size 1 when oil. SEM microimages EDS analysis MAF could improve quality Ni-Ti finish.
