The ceramic particle reinforced iron matrix composites not only have the advantages of good strength and impact toughness of iron matrix,but also have the advantages of high hardness and high wear-resistance of ceramic particles.They have broad application prospects in improving the wear-resistance of materials,and have become one of the research hotspots at home and abroad in recent years.Based on the research results of existing domestic and foreign literatures,firstly,the composition design of ceramic particle reinforced iron matrix composite cladding layer is introduced from the selection of iron matrix and ceramic particles.Secondly,the preparation methods of iron-based composite cladding layers such as electrode arc surfacing,gas shielded arc surfacing,plasma arc surfacing,submerged arc surfacing and laser cladding are introduced in detail.Thirdly,the influence of different ceramic particles on the microstructure,hardness and wear-resistance of the iron matrix composite cladding layer is discussed by analyzing the type,quantity,size and shape of ceramic particles and the matching condition with the iron matrix.Finally,the future development trend of ceramic particle reinforced iron matrix com-posite cladding layer is prospected.
