Abstract

The invention discloses a tungsten oxide alloy material and a preparation method thereof, and relates to the technical field of alloy materials. The tungsten oxide alloy material is composed of 0.3%-0.5% of C, 1.5%-2.0% of B, 5%-10% of Ni, 5%-10% of W, 0.5%-1.5% of La, 2.0%-2.5% of Ta, 2.0%-2.5% of Re, 2.0%-2.5% of Mo, 2.5%-5% of Ti, 1.0%-1.5% of Y, 5%-10% of K,5%-10% of V and the balance iron. According to the tungsten oxide alloy material and the preparation method thereof, due to the microalloying effect of elements such as Ni, Cr, W and Re, the wear resistance and the corrosion resistanceare greatly improved, the thermal shock resistance and the crack resistance are improved, meanwhile, the hardness is proper, machining is facilitated, the yield can be increased, and resource consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of alloy materials, and particularly discloses a tungsten oxide alloy material and a preparation method thereof. Background technique [0002] At present, entering the 21st century, the level of industrialization is developing rapidly, but the natural environment and ecology on which human beings depend have been severely damaged. There are a large number of toxic and harmful gases (such as NO2, NO, H2S, CO, SO2, etc.) in the air. NOx toxic gases can form acid rain, corrode buildings and skin, and can also produce chemical fumes, which can cause coughing when inhaled, and even cause respiratory diseases. Therefore, it is urgent to make sensors for efficient and accurate detection and prevention of toxic and harmful gases. To obtain high-performance nanosensors, it is first necessary to prepare nanomaterials that can provide these high-performance possibilities. [0003] Metal-oxide-semiconductor-type gas s...
