Preparation method for particle-reinforced iron-based surface composite material

The invention relates to a method suitable for preparing a particle-reinforced iron-based surface composite material and belongs to the field of metal-based composite materials. The method adopts appropriate ceramic particles, a spark plasma sintering technology, a pouring technology and a heat treatment technology, and the particle-reinforced iron-based surface composite material is obtained. A composite layer and a base material as well as the ceramic particles and a base body are all well combined. The abrasion resistance of the particle-reinforced iron-based surface composite material is improved to a great extent by adding the ceramic particles. 本发明涉及种适于制备颗粒增强铁基表面复合材料的方法，属于金属基复合材料领域。本发明采用合适的陶瓷颗粒、放电等离子烧结工艺、浇注工艺以及热处理工艺，制备得到陶瓷颗粒增强铁基复合材料。复合层与基材以及陶瓷颗粒与基体均结合良好，加入陶瓷颗粒很大程度上提高了材料的耐磨性能。
