用1.91kW连续CO_2激光得到了部分非晶态,用4.5kW及4.9kW得到了单道纯非晶及多道搭接成片部分晶化非晶涂层。所得动电位极化曲线表明,非晶态Ni_(60)Nb_(40)的耐腐蚀性远优于晶态的Ni_(60)Nb_(40),在Ni-Nb中加Cr所得非晶涂层其耐腐蚀性有很大提高,且优于18-8不锈钢。
Partially amorphous Ni_(60)Nb(40) alloy coatings was made using 1.91 kW cw CO_2 laser melt-quenching, and fully amorphous using 4.5 kW and 4.9 kW. The corro sion resistance of the amorphous layer was improved by adding Cr. Potentiodynamic polarization curves show that Ni_(50)Nb_(40)Cr_(10) is much more corrosion-resistant than stainless steel 18-8.
