Abstract

The invention relates to a preparation device and method for nearly-spherical titanium carbide coated high-speed steel composite powder. The device system comprises a stock bin, a fluidized bed reactor, a titanium source generator, a product collecting device and a tail gas treatment device. High-speed steel powder is subjected to vapor deposition in a fluidized state in the device, so that approximately-spherical titanium carbide coated high-speed steel composite powder is obtained, uniform distribution of titanium carbide on the microscopic scale is achieved, the shape of titanium carbide is adjusted to be converted into approximately-spherical shape from a feather shape and a rod shape, and the performance of powder metallurgy high-speed steel is remarkably improved.

Description

technical field [0001] The invention belongs to the field of powder metallurgy of steel alloys, in particular to a preparation method of a coated high-speed steel composite powder, in particular to a preparation device and a preparation method of a near-spherical titanium carbide coated high-speed steel composite powder. Background technique [0002] As a tool material, high-speed tool steel has a history of nearly 100 years. Due to its high strength, high hardness and high red hardness, it is still of great significance in the processing field. High-speed steel is often used to prepare cutting equipment such as taps, dies, drills, and knives. High-speed steel is developed from a TI-Mn self-hardening steel with a high carbon content. In addition to carbon, its main alloying elements are TI, Mo, Cr, and V. In addition, some high-speed steels add Co, Si, Ti, Nb, Zr, Hf, Cu, Ni, Mn and rare earth elements to improve the structure and performance. According to the role of allo...
