Abstract
A kind of nickle-base corrosion-resisting spark plug cathode material, it is characterised in that：Described drug core component mass percent：Metallic nickel：56～74%；Crome metal：21～40%；Metallic aluminium：5～9%；Metallic copper：2～4%；Boron：2～6%；Magnesium 2～6%；Y：0.5～1%；RE：0.5～2%.Due to the addition of RE, metallographic research has shown that the present invention, and element Main Function in the material is：Purification, alloying.Its particularly evident structure for improving material, improve the as-cast structure of steel alloy, enhance the compactness of material and facilitate matrix to combine, so as to effectively raise high-temperature oxidation resistance and corrosion resistance, and refining alloy crystal grain, high temperature strength is improve, the service life of material product is extended, cost is reduced again.
Description
Technical field
The invention belongs to the Surface Engineering field in Materials Processing Engineering, is mainly used in the spark plug cathode material of medium-to-high grade car.
Background technology
The spark plug cathode material of medium-to-high grade car is the cupro-nickel series alloy material based on copper, nickel at present.Motorcycle spark plug cathode material is based on iron-based series.The corrosion resistance of both materials, non-oxidizability are poor, easily cause spark plug fouling.Because carbon distribution, it is unstable to cause engine operating condition, hydraulic performance decline.If having carbon distribution between the spark plug electrodeposition in combustor, generally, the electric spark that send can spark plug is weaker.When serious, short circuit is easily caused, affect engine work, power drop.
Content of the invention
For above deficiency, it is an object of the invention to provide a kind of nickle-base corrosion-resisting spark plug cathode material so as to fully meet the property indices of similar products at home and abroad.
The technical scheme is that and be accomplished by：A kind of nickle-base corrosion-resisting spark plug cathode material, it is characterised in that：Described drug core component mass percent：Metallic nickel：56～74%；Crome metal：21～40%；Metallic aluminium：5～9 %；Metallic copper：2～4%；Boron：2～6%；Magnesium 2～6%；Y：0.5～1%；RE：0.5～2%.
Due to the addition of RE, metallographic research has shown that the present invention, and element Main Function in the material is：Purification, alloying.Its particularly evident structure for improving material, improve the as-cast structure of steel alloy, enhance the compactness of material and facilitate matrix to combine, so as to effectively raise high-temperature oxidation resistance and corrosion resistance, and refining alloy crystal grain, high temperature strength is improve, the service life of material product is extended, cost is reduced again.
Specific embodiment
Embodiment 1：
A kind of nickle-base corrosion-resisting spark plug cathode material, described drug core component mass percent：Metallic nickel：56%；Crome metal：32%；Metallic aluminium：5%；Metallic copper：4%；Boron：1%；Y：0.5-1%；RE：0.5～1%, remaining is magnesium.
Embodiment 2：
A kind of nickle-base corrosion-resisting spark plug cathode material, described drug core component mass percent：Metallic nickel：70%；Crome metal：23%；Metallic aluminium：7%；Metallic copper：6%；Boron：2%；RE：0.6～1.2%, remaining is magnesium.
The present invention is due to the addition ofRare earth elementYttrium, research have shown that element Main Function in the material is：Its resistance to high temperature oxidation thing can be significantly improved, high-temperature behavior, oxidation resistance and the ductility of steel is improved.The as-cast structure of steel alloy, enhances the compactness of material and facilitates matrix to combine, so as to effectively raise high-temperature oxidation resistance and corrosion resistance, and refining alloy crystal grain, improve high temperature strength, extend the service life of material product, reduce cost again.
