Abstract

The invention discloses energy-saving type zinc alloy containing Re for white spot and black spot free steel wire hot-dip galvanizing and a machining process for the zinc alloy. The alloy comprises the ingredients of, in percentage by weight, 0.4-0.6% of Ba, 0.3-0.8% of Se, 0.4-0.6% of Re, 1.2-1.5% of Ge, 0.4-0.6% of Mo, 0.5-0.8% of Bi and the balance zinc. By means of the energy-saving type zincalloy containing Re for white spot and black spot free steel wire hot-dip galvanizing and the machining process for the zinc alloy, development of the high-quality zinc alloy for hot-dip galvanizing is facilitated, the zeta-free phase galvanizing layer can be obtained, and white spots and black spots of the plating layer can be inhibited.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a zinc alloy. Background technique [0002] Since the standard electrode potential of zinc is negative to that of iron, the galvanized layer has the effect of sacrificial anode protection of the steel base in water and humid air, which can greatly prolong the service life of the steel. Hot-dip galvanized steel sheet is the most widely used hot-dip galvanized product. After the workpiece is galvanized, when the zinc layer is very dense, it can effectively separate the substrate of the plated part from the external environment medium, so that the plated part is not corroded by the external environment medium; when the surface of the coating layer is damaged or has pores, the zinc As a sacrificial anode, it dissolves preferentially and has a protective effect on the steel matrix, so it is widely used as an anti-corrosion material for steel. The galvanized layers commonly used in in...
