Sacrificial layer cladding powder based on Leidenfrost effect and application of sacrificial layer cladding powder in powder core wire electric arc additive material
The invention discloses sacrificial layer cladding powder based on the Leidenfrost effect and application of the sacrificial layer cladding powder in powder core wire electric arc additive materials. The cladding powder comprises ceramic matrix powder and sacrificial layer cladding powder. The application comprises the following steps: 1) taking the sacrificial layer cladding powder as ceramic particles for additive manufacturing; and (2) the ceramic particle reinforced metal matrix composite is manufactured based on the ceramic particles. The surfaces of the ceramic particles are coated with the sacrificial layers, in the arc additive manufacturing process, the sacrificial layers are instantly gasified in an arc high-temperature area to form a steam layer, dissolution of the inner-layer ceramic particles can be effectively avoided, and the forming quality of powder core wire arc additive manufacturing is improved.
一种基于莱顿弗罗斯特效应的牺牲层包壳粉末及其在粉芯丝材电弧增材中的应用，包壳粉末包括陶瓷基体粉体、牺牲层包覆粉体；应用包括：1)将上述牺牲层包壳粉末作为用于增材制造的陶瓷颗粒；2)基于陶瓷颗粒，制造陶瓷颗粒增强金属基复合材料。本发明在陶瓷颗粒表面包覆一层牺牲层，在电弧增材制造过程中，牺牲层在电弧高温区瞬间气化形成蒸汽层，可以有效避免内层陶瓷颗粒的溶解，提升粉芯丝材电弧增材制造的成形质量。
