Abstract

The invention provides a rapid preparing method of a Zr-based electrochemical amorphous alloy. The method comprises the following steps that firstly, Mg3B2, or Ca3P2 and zirconocene dichloride are put into a zirconium dioxide ball mill tank, then, benzene is used as an anti-bonding agent or diluting agent, and argon is inflated for sealing the tank; secondly, positive rotation and reverse rotation crossing is carried out for ball milling; thirdly, in a vacuum glove box, the tank is opened, and in an ethyl alcohol solvent, after sediment is removed, a glass ware is sealed for standby application; fourthly, the ethyl alcohol serves as the solvent, polycation salt serve as a first main salt main component, third-period later-transition group element acetate including Cu serve as a second main salt main component, tetra-n-butylammonium bromide serves as conductive salt, alkali metal oxalate, citrate, tartrate or ethylene diamine tetraacetic acid serves as a complexing agent, and under a certain current density, a selected steel workpiece base body is plated.

Description

Technical field [0001] The invention relates to the technical field of electrochemical amorphous alloys, in particular to a Zr-based electrochemical amorphous alloy and its rapid preparation. Background technique [0002] Because electrochemical amorphous alloys have the characteristics of low cost, large area plating and new alloys that can be obtained by metallurgical methods, their rapid preparation research has attracted much attention. However, the current focus is mainly on the alloying of the eighth group elements with (P, B, C, S) and other elements. Zr, which has excellent corrosion resistance, is due to the difference in reduction potential of its single salt or complex salt and other elements and its plating The complexity of the liquid results in low stability and it is difficult to quickly co-deposit to obtain the corresponding electrochemical amorphous alloy. [0003] In view of this, it is necessary to study a rapid preparation method for electrochemical amorphous a...
