Spray forming technology is a promising and potential preparation technology, which has great advantages in the forming and preparation of high alloy materials. The principle of spray forming technology of hardfacing wear-resistant steel plate is that the hardfacing wear-resistant steel plate is atomized into fine dispersed droplets under the action of high pressure inert gas, and then rapidly cooled to supercooled state in the process of high-speed flight, and then deposited on the collector to form continuous and dense near net shape billet before solidification.
The spray forming process of wear-resistant steel plate is greatly simplified, the production cycle is shortened, and the cost is greatly reduced; The cooling rate is up to 103K / s. Thus, the macro segregation is eliminated and the fine equiaxed microstructure is obtained.
Moreover, it has high deposition rate, and the quality of a single product is usually more than 1t, which is conducive to industrial production; High alloy, excellent properties, spray forming material properties ( Such as corrosion resistance, wear resistance, magnetism, strength and toughness and other physical, chemical and mechanical properties ) It is equivalent to powder metallurgy material and higher than conventional casting material.
It has a wide range of applications, can produce a variety of alloys, especially in superalloy, hardfacing wear-resistant steel plate and other high alloying materials has obvious advantages, in hardfacing wear-resistant steel plate matrix composites also has broad application prospects.
At present, spray forming technology of hardfacing wear-resistant steel plate is mainly used for the research and development of various high-performance alloy products, including aluminum alloy, copper alloy, wear-resistant plate, tool steel, hardfacing wear-resistant steel plate, roll alloy and superalloy. Its application scope involves automobile, petrochemical, electronics and many common industrial fields.
