Coating of High Corrosion Resistant Amorphous Stainless Steels by RF Sputtering(Materials, Metallurgy & Weldability)

Corrosion resistant amorphous (SUS316)_<100-x>Zr_x stainless steels were prepared by R.F. magnetron sputtering in argon gas. The alloying of zirconium effectively stabilizes the amorphous structure in zirconium content from 3.2 at% to 47.7 at%. The corrosion resistance of (SUS316) stainless steel in 1N HCl was definitely improved by amorphization. Although the high corrosion resistance is realized against the smooth and flat surface of the amorphous stainless alloys, an increase in surface roughness degrades the corrosion resistance. The (SUS316)_<100-x>Zr_x amorphous stainless steels with high microhardness represent the high maximum value at zirconium content of 30 at%, suggesting the local bonding of zirconium and iron.
