Problems solved by technology
[0002] Applied in the material tube of injection molding machine, a layer of alloy is coated on the inner surface of the material tube through the process of melting and centrifugation. The problem existing in the existing scheme is mainly that the alloy layer is not uniform during the cladding process of the alloy powder, and the hardness cannot reach 70HRC.
The main problem in the application of existing iron-based powders is that the alloy layer of the barrel is unevenly distributed during the cladding process, and the hardness cannot meet the requirements.

Description
technical field [0001] The invention relates to the metallurgical industry for improving the hardness of metal surface materials, in particular to a high-alloy iron-based self-fluxing powder. Background technique [0002] It is applied to the material tube of injection molding machine, and the inner surface of the material tube is coated with a layer of alloy through the process of melting and centrifugation. The problem with the existing solution is that the alloy layer is not uniform during the cladding process of the alloy powder, and the hardness cannot reach 70HRC. The main problem in the application of existing iron-based powders is that the alloy layer of the barrel is unevenly distributed during the cladding process, and the hardness cannot meet the requirements. Contents of the invention [0003] Regarding the current situation of the above-mentioned prior art, the technical problem to be solved by the present invention is to provide a kind of high-alloy iron that...
