Partially amorphous Ni-Nb alloy was made by 1.91 kW cw CO_2 laser melt-quenching, and fully amorphous by 4.5 kW and 4.9 kW.The corrosion resistance of the amor- phous layer was improved by adding Cr.Potentiodynamic polarization curves show that the amorphous Ni_(50)Nb_(40)Cr_(10) is in more corrosion-resistant than the amorphous Ni_(60)Nb_(40)and 18-8 stainless steel.
