Abstract
The invention relates to a novel cathode protection used high-performance magnesium alloy galvanic anode material, and belongs to the technical field of new materials. The material provided by the invention is prepared by alloying and smelting an AZ31 magnesium alloy, which is used as a base material, with eight types of alloy elements Ce, Ca, Cd, Y, Sn, Ga, In and Ti added. The prepared novel high-performance magnesium alloy galvanic anode material overcomes the defects such as low current efficiency of a current internationally-used galvanic anode material. Compared with the performance of GB/T17731-2004 magnesium alloy anode series, the material provided by the invention has the characteristics of low open circuit potential, high current efficiency, a low self-corrosion rate and the like.
Description
Technical field
The invention belongs to new material technology field.
Background technology
Data shows, and the financial loss that metallic corrosion causes is surprising, accounts for about 3% of gross national product.Therefore, study protection against corrosion new technology, exploitation protection against corrosion novel material is significant.
Electro-chemical protection is a kind of effective ways preventing metallic corrosion; sacrificial protection is the one of electro-chemical protection method; the method is electrically connected with protected body (hardware) by means of the alloy electrode that the more protected body of current potential is more negative, turns to cost protected body is reached exempt to lose effect with the alloy ion that this current potential is more negative.Therefore, alloy appellation sacrificial anode more negative for this current potential.The chemical property of sacrificial anode determines the economy of the feasibility of the method, Application Areas and enforcement.Sacrificial anode general in the world has three classes at present: magnesium base anode, zinc-base anode and al base sacrificial anode.Relative to zinc, aluminium two kinds of metallic substance, magnesium anode has higher energizing voltage and theoretical current capacity, wide material sources, features such as low price and being well used in engineering.
(the conventional trade mark is as AZ31 at present both at home and abroad conventional magnesium alloy anode, AZ91, AZ63 etc.) in usually containing Fe, Ni, the impurity elements such as Cu and Co, impurity element and magnesium form intermetallic compound, add the autolyzed of magnesium, there is watt current capacity little, the drawback that the current efficiency ratio of theoretical current capacity (the watt current capacity with) is low, the utilization ratio of the current capacity of magnesium anode is about about 50%, the magnesium alloy anode of nearly 50% is because of corrosion certainly, evolving hydrogen reaction, ion erosion consumes useless for no reason, not only cause the waste of resource, protection against corrosion cost raises, also limit the Application Areas of magnesium alloy anode simultaneously.Therefore the efficient magnesium of development of new closes and sacrifices the high magnesium-alloy anode material of gold anode material, particularly current efficiency, has important theoretical and practical significance.
The corrosion and protection of the metal structures in Seawater has special significance, due to the special property such as severe corrosive of seawater, at present, usually adopts zinc-base anode as the sacrificial anode material of galvanic protection.The theoretical current capacity of zinc anode material is low, seriously polluted, even if also there will be highdensity lattice defect in the crystal boundary area of high purity zinc anode, causes the non-uniform corrosion of rolled tin to be peeled off.And magnesium alloy anode because of its suppression low from corrosive nature, the application in seawer system still belongs to blank.Efficient, the eco-friendly galvanic protection sacrificial anode material of Application and Development in seawater, its market outlook are very wide.
The object of the invention is, little for current sacrificial magnesium alloy anode watt current capacity, the shortcoming that current efficiency is low, develop a kind of novel high-performance magnesium alloy sacrificial anode material, compare with GB/T17731-2004 series magnesium alloy anode, have that open circuit potential is low, current efficiency is high, from features such as erosion rate are little.Thus reduce galvanic protection cost, widen the Application Areas of sacrificial protection.
