 Abstract:
Low pressure die casting is an important industrial casting process used for the mass production of aluminum alloy wheels. The cost effectiveness of the process is dictated by the rate at which components can be produced and the working life of the dies. In low pressure die casting, the surface of the die component, which is contacted by molten metal, is provided with a die coating. The main function of the coating is to provide a degree of insulation which is intended to prevent premature solidification of the molten metal, and thereby enable the complete filling of the die cavity before solidification starts. However, the coating also is to protect the steel die surfaces from erosion or corrosion by impingement by or contact with molten metal. In this study, appliciability of the flexicord flame sprayed thermal barrier coatings on die surface are investigated and discussed.
