Abstract

The invention relates to a rapid-corrosion magnesium alloy product. The alloy product comprises the following components in percentage by weight: 1-6% of aluminum, 1-6% of zinc, 1-3% of iron, 5-15% of copper, 0.1-1% of silver, 0.1-1.2% of nickel and the balance of magnesium. Meanwhile, the invention also discloses a preparation method of the alloy product. The effects of aluminum and zinc are fully utilized to improve the strength and hardness of the magnesium alloy, copper, iron, silver and nickel are used for improving the corrosion rate; by regulating and controlling the ratio among metal elements, the mechanical properties and corrosion rate are greatly increased and thus the purposes that the magnesium alloy product can be used as a structural member and can protect a device and the magnesium alloy product can be rapidly dissolved under certain conditions are achieved.

Description

technical field [0001] The invention relates to the technical field of metal alloy materials, in particular to a rapid corrosion magnesium alloy product and a preparation method thereof. Background technique [0002] Magnesium alloy is an alloy composed of magnesium as the matrix and adding other elements. It is characterized by low density (about 1. 8g / cm3 magnesium alloy), high specific strength, large elastic modulus, good heat dissipation, good shock absorption, and The impact load capacity is greater than that of aluminum alloy, it is the lightest metal among practical metals, with high strength and high rigidity. With the development of industry, more and more metal materials are used, so the problem of corrosion and corrosion protection becomes more and more important. [0003] There are many kinds of metal corrosion, electrochemical corrosion is one of the most important corrosion, and cathodic protection is an important metal electrochemical corrosion protection me...
