Magnetic Properties of Austenitic Stainless Steel 316l and 316lvm after High Temperature Gas Nitriding Treatment
Abstract: Biometallic
materials for implant devices not only have to good corrosion resistance but
also stable nonmagnetic properties. Various method have been developed for
enhanced the corrosion resistance i.e low temperature gas nitriding treatments.
Unfortunatelly, low temperature gas nitriding produce weakly ferromagnetic due
the presence of expanded austenitic phases. Another treatments methods which is
capable for improvement the mechanical properties is high temperature gas
nitriding. However, the evaluation of magnetic properties of austenitic
stainless steel 316L and 316LVM not yetinvestigation. The evaluation of
magnetic properties of austenitis stainless steel 316L and 316LVMafter high
temperature gas nitriding treatments have been succesfully done. The magnetic
properties are evaluated by vibrating sample magnetometre (VSM) test. The
magnetic properties such asmagnetic remenance, magnetic saturation and magnetic
permeability are improved. As treated 316Land 316LVM have more stable
non-magnetic properties and they more safe and compatible for MRItest.
