Product Description

Related to the technical field of alloy materials, and disclosed corrosion resistant high strength and high conductivity copper, aluminum and rhenium rare earth alloy materials including the following weight ratio of raw materials: copper 0.060.12, rhenium powder 0.080.18, rare earth 0.040.10 and aluminum surplus. The corrosion resistance of high strength and high conductivity copper, aluminum and rhenium rare earth alloy materials and preparation method, through the process of melting and casting and hot extrusion of copper, rhenium powder, rare earth and aluminum into alloy materials, aluminum has good ductability, can be aluminum into the required shape, at the same time aluminum in the humid air can form a layer to prevent metal corrosion of oxide film, increase the oxidation resistance of alloy materials, copper and rare earth Has good grounding connectivity and excellent resistance to soil corrosion, rhenium melting point is higher in which has good heat resistance, so that the grounding system is not easy to cause the high temperature of the grounding material when struck by lightning or disconnect, the overall realization of alloy materials of high corrosion resistance and conductive properties of the purpose, in line with the concept of environmental protection.
Aluminate coating was prepared on nickel base high temperature alloy DD32 by low pressure vapor deposition. The outer layer of the coating is β-NiAl, the inner layer (diffusion layer) is close to the width of the outer layer, enriched in Re. After 500 h oxidation at 900ºC and 1000ºC, the surface oxide films are dense α-Al_2O_3 and acicular θ-Al_2O_3, and the oxidation kinetics basically conform to the parabolic law. The outer layer of the oxidized aluminum coating is β-NiAl, and Al-poor Ni_3Al precipitates along the grain boundary. The matrix of the inner layer (diffusion layer) is Ni_3Al, and massive Re - and W - rich compounds are precipitated.
