Abstract

The invention belongs to the technical field of fuse high-efficiency additive manufacturing, and discloses a steel-titanium composite material fuse high-efficiency additive manufacturing system and preparation method. The method comprises the following steps that firstly the three-dimensional modeling of a to-be-processed part of a composite material is carried out, the layered slicing is carriedout, printing parameters are adjusted through a control assembly, a to-be-processed steel substrate is fixed, a heat source and a wire feeding assembly for a transition material are started to complete one-layer fused deposition of a transition layer, then the heat source and the wire feeding assembly for a titanium wire are started to complete one-layer fused deposition of a titanium layer, the opening and closing of the wire feeding assembly for the transition material, the wire feeding assembly for the titanium wire and the wire feeding assembly for a steel wire are correspondingly adjustedaccording to the requirements of a to-be-processed part, and the fuse high-efficiency additive of the multi-layer steel-titanium composite material is completed. According to the steel-titanium composite material fuse high-efficiency additive manufacturing system and preparation method, the adopted technology is flexible in the technology, high in flexibility, short in period and friendly to theenvironment, and the prepared steel-titanium composite material can be steel-titanium double-layer composite or steel-titanium-steel-titanium multi-layer composite as well, and the number and mode ofcomposite layers are not limited.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency additive manufacturing of fuses, and in particular relates to a high-efficiency additive manufacturing system and a preparation method of steel-titanium composite fuses. Background technique [0002] Titanium and titanium alloys have low density, high specific strength, good plasticity and toughness, sufficient corrosion resistance and high temperature strength, and are widely used in aerospace, biomedical, and petrochemical fields. Steel is the most widely used material in the national economy. It has high strength, good rigidity, and good thermal conductivity, but poor corrosion resistance. The titanium-steel composite material has the common advantages of the two materials, not only has corrosion resistance, high strength, and low price, it is a new type of composite material with high cost performance. However, due to the extremely low solubility of iron in titanium, it is easy to for...
