Corrosion Resistance of Medical Stainless Steel Obtained by Non- Vacuum Electron Beam Cladding

摘要

Pitting and crevice corrosion resistance of 321 stainless steel and non-vacuum electron-beam cladded stainless steel have been investigated by using potentio-dynamic polarization curve plotting. Lock-Ringer Salt Solution (LRSS) was used as biological media for corrosion test measurements. Microstructural research of samples after corrosion was carried out by using scanning electron microscopy. The experimental results show that the cladded stainless steel possesses higher pitting and crevice corrosion resistance.
