What is Dross Defects in Casting Processes about?

It consists mainly of magnesium oxy-silicates and magnesium sulphides formed from a reaction of magnesium with oxygen, sulfur, and silicon. Dross is commonly found in the upper casting surface or beneath cores, and reduces mechanical properties like vibrostability by up to 50%. While dross cannot be prevented, its formation can be reduced through measures related to melt treatment, pouring, and casting proce
