3mol/L的HCl溶液中的变温失重腐蚀行为

与304不锈钢相比

Ti40Cu39Ni11Zr10块体非晶具有优异的耐腐蚀性能。

Abstract

Ti40Cu39Ni11Zr10bulky alloys with different diameters from 2mm to 4mm were prepared by using copper mold casting method.The structure and thermal stability of the bulky amorphous alloys prepared were investigated by means of X-ray diffractometry（XRD）

scanning electron microscopy（SEM）and differential scanning calorimetry（DSC）.Its corrosion resistance was evaluated by conducting electrochemical corrosion test and variable temperature weightless corrosion in 3mol/L HCl solution.Results show that 2mm in diameter for glass formation is only obtained of the Ti40Cu39Ni11Zr10 bulky alloys

and it exhibits acceptable thermal stability.The TiCu phase is precipitated in amorphous matrix for increasing size to 3mm and 4mm.The corrosion behavior of between Ti40Cu39Ni11Zr10 bulky amorphous alloy and the 304 stainless steel was investigated comparatively by electrochemical method in3.5% NaCl solution and by variable temperature weightless corrosion at 303 K

318Kand 333 Kin 3mol/L HCl solution.Compared with the 304 stainless steel

the Ti40Cu39Ni11Zr10 bulky amorphous alloy have a better corrosion resistance.
