Beschreibung
Zusammenfassung:	The invention provides a preparation technology of a three-dimensional printing composite material based on micron-order stannum-based Babbitt powder. The preparation technology comprises the following steps that a stannum-based Babbitt ingot flows out of a drainage mouth after being subjected to high-low-temperature circulation embrittlement treatment, through a secondary laminated flow spray system composed of a confined type nozzle and a tight coupling nozzle, a metallic liquid is atomized and broken into droplets by adopting the nozzles to eject high-pressure airflow, and the droplets areseparated, cooled and solidified under the action of free fall and centrifugation to obtain the stannum-based Babbitt powder; carbon steel is subjected to air cooling after heat treatment, then the carbon steel is immersed in a tin furnace for coating treatment after preheating and taken out, the carbon steel is subjected to ultrasonic cleaning after being polished with raw emery paper, and nitrogen blow-drying is carried
