Abstract

The invention provides a method for preparing spherized cobalt-chromium-molybdenum alloy powder for micron-level additive material manufacturing. The adopted raw material is irregular cobalt-chromium-molybdenum alloy powder prepared through water atomization, and the micron-level spherical cobalt-chromium-molybdenum alloy powder with the irregular shape, the high nodularity larger than or equal to90%, the high sphericity degree and the high stacking density can be obtained through adjusted experiment parameter spheroidizing, and the spherical cobalt-chromium-molybdenum alloy powder can be directly used for additive material manufacturing due to good mobility.

Description

technical field

[0001] The invention belongs to the technical field of materials, and in particular relates to a method for preparing spherical cobalt-chromium-molybdenum alloy powder for micron-scale additive manufacturing. Background technique

[0002] Micron-sized spherical metal powders are widely used in the field of additive manufacturing, and compared with other types of materials (foils, bulk materials), powder materials have many advantages, such as easier preparation, high material utilization, Wide range of categories, simple construction process, etc. In the additive manufacturing process, selective laser melting molding (SLM), laser near net shaping (LENS), electron beam melting molding (EBM), etc. are all used in the role of micron-sized spherical metal powder materials in the energy source. Formed by melting and accumulating.

[0003] Whether it is domestic or foreign, there are many research and development units that have carried out research and developme...
