Abstract

Refractory coatings are a key factor in the casting process

and the performance of the coating directly affects the quality of the castings.In the production of lost foam casting

the defects such as poor gas permeability

low temperature strength and poor peelability have a great effect on the quality of castings.The optimization of coating formulation and the influence of coating on casting quality have become the hotspots of current research.Combined with the defects of ductile iron lost foam coatings

the requirements of coatings for ductile iron castings were analyzed.The formulation and process of ductile iron lost foam coatings

coating properties

coatings on the defects of ductile iron castings were analyzed.The research direction of ductile iron lost foam coatings was analyzed.
