Embodiment 1

[0035] The invention relates to a method for preparing a zirconium-silver alloy target, comprising the following steps:

[0036] (1), weighing and mixing: the nuclear-grade spongy metal zirconium (the purity of zirconium is 99.8%) and silver scraps with a purity of 99.99% are weighed and mixed according to the mass percentage of 98% for zirconium and 2% for silver;

[0037] (2) Electrode pressing: place the mixed metal zirconium and silver alloy materials in a nitrogen protective atmosphere to prevent the materials from being damp and oxidized, and put the prepared zirconium silver materials evenly into the press to press them into electrodes. Each electrode is controlled at 6kg, in which zirconium and silver are evenly mixed and clothed, and the pressed electrode is placed in a nitrogen protective atmosphere to prevent the material from being damp and oxidized;

[0038] (3) Welding electrodes: The two pressed electrodes are welded into smelting electrodes by tungsten argon ar...

Abstract

The invention provides a zirconium-silver alloy target and a preparation method and an application thereof, and relates to alloy targets. The zirconium-silver alloy target is composed of 97-99.5% of zirconium and 0.5-3% of silver according to mass percent. The preparation method includes the following steps: mixing nuclear grade sponge stage metal zirconium with silver chips to obtain a zirconium and silver mixture; pressing the zirconium and silver mixture into electrodes, placing the electrodes in a nitrogen atmosphere environment to prevent dampness and oxidation of the material; welding each two electrodes into a melting electrode; melting the melting electrode to obtain primary zirconium-silver ingots; deheading and smoothing the tails of the primary zirconium-silver ingots, welding each two primary zirconium-silver ingots into a secondary zirconium-silver melting electrode; melting the secondary zirconium-silver melting electrode to obtain secondary zirconium-silver ingots; hot forging the secondary zirconium-silver ingots to eliminate coarse-grain generated in the melting process and homogenize the tissues, carrying out a heat treatment and cooling, and processing the necessary zirconium-silver alloy target according to the size specification of the target. The prepared zirconium-silver alloy target is free of such defects as obvious pore, segregation and the like, and is uniform in tissue size.

Description

technical field [0001] The invention relates to an alloy target material, in particular to a zirconium-silver alloy target material and a preparation method and application thereof. Background technique [0002] At present, in the surface treatment and decoration industry, multi-arc zirconium targets are generally used for surface decoration coating, and various decorations with excellent corrosion resistance are obtained by feeding reactive gases such as nitrogen, argon, acetylene, etc. during the coating process. Sexual color film. The antibacterial film layer is usually sputtered with a layer of silver film to achieve antibacterial and antibacterial effects, but due to the poor stability of silver in the atmosphere and poor corrosion resistance, the color of the product will change and corrosion will occur on the surface, which seriously affects the quality of the product. Appearance quality, but not able to be applied in practice. [0003] Chinese invention patent 2009...
