Definitions

  • the halogen containing compound is provided in a coating applied to at least a portion of the mould surface which forms at least part of the mould cavity.
  • the method further includes the step of subjecting the article to isostatic pressure.
  • the method further includes the step of heating the article to a temperature at which the entire article remains solid whilst applying the isostatic pressure. Subjecting the article to an isostatic pressure, particularly at high pressure, generally eliminates internal pores within the cast article, which improves the mechanical integrity of the article and reduces the risk of any such pores being exposed at the article surface during machining of the article.
  • a mould 12 is formed from first 12a and second 12b mould parts made from zircon or silicon sand using conventional sand-casting techniques.
  • the cylindrical portions of an upper mould part 12a which form cylindrical cavities, i.e. the cylinders in the engine block, are then coated with a coating 14 containing a halogen such as fluorine.
  • the halogen is fluorine
  • the coating material contains dipotassium fluorotitanate powder (K 2 TiF 6 ).
  • Other halogen containing compounds such as a mixed potassium chloride - magnesium chloride eutectic, potassium borofluoride, or aluminium chloride may alternatively be used.
