Description
Technical Field
The invention belongs to the field of alloy processing, and particularly relates to a high-temperature wear-resistant corrosion-resistant alloy and a production process thereof.
Background
An alloy is a substance with metallic characteristics, which is synthesized by two or more metals and metals or nonmetals through a certain method. Typically by melting to a homogeneous liquid and solidifying. According to the number of constituent elements, binary alloys, ternary alloys, and multi-element alloys can be classified. The heat-resistant alloy is also called as high-temperature alloy, and has great significance for industrial departments and application technical fields under high-temperature conditions. Generally, the higher the melting point of the metal material, the higher the temperature limit at which it can be used. This is because the mechanical properties of the metal material are significantly reduced with the increase of temperature, and the tendency of oxidation corrosion is increased, so that the general metal material can only work at 500-600 ℃ for a long time. Metals that can operate at high temperatures above 700 ℃ are known as heat resistant alloys. "Heat resistant" means that it retains sufficient strength and good oxidation resistance at high temperatures. The alloy after being treated at present has the use temperature of 1000-1100 ℃.
The high-temperature alloy can be applied to temperature sensors and high-temperature wear-resistant corrosion-resistant parts of nozzles in hydrogen chloride and high-temperature hydrogen sulfide secondary environments of garbage incinerators, biomass boilers, cement rotary kilns and chemical reactor systems. However, the existing high-temperature alloy can not meet the service condition of being more than 1100 ℃ for a long time, particularly can not exceed more than 800 ℃ in the service environment of hydrogen chloride or hydrogen sulfide, and the corrosion resistance and the wear resistance of the alloy can be deteriorated and the service life is very short when the alloy exceeds a specific temperature, and the existing alloy is difficult to achieve particularly in the service environment which needs wear resistance in the high-temperature environment. The alloy is easy to carbonize at the temperature of more than 1100 ℃, has low hardness and poor high-temperature resistance and wear resistance, and is more easy to generate phenomena of abrasion, bending and corrosion in the use environment with hydrogen chloride and hydrogen sulfide.
