Abstract (en)
The present invention refers to a method for enamelling cast parts made of standard hypoeutectic gray iron, comprising following steps: - preparing a cast part of standard hypoeutectic gray iron; - pre-treating said cast part in order to promote mechanical bond and adherence of the enamel substances to the surface of the part to be enamelled; - applying porcelain-enamel powders onto the thus pre-treated part by dry electrostatic spray technique; - vitrifying the enamel powders by exposing the part to a heating and cooling sequence occurring according to such a heating and cooling pattern versus time as to cause the part to dwell at a temperature between 700°C and 780°C for 480 seconds ± 5%.
