  • Variable-permeability pattern coating for lost foam casting
    Patent number: 4482000
    Abstract: A vaporizable pattern for casting reduced porosity metal by a lost foam process is coated with a thermally insulative, predominantly refractory particulate layer comprising polymeric particles. During metal casting, the refractory particles insulate the polymeric particles to delay vaporization, whereupon pattern decomposition vapors build up and slow metal replacement of the pattern to reduce vapor-entrapping turbulence. Subsequent vaporization of the polymeric particles produces pores in the residual refractory coating wherethrough pattern decomposition vapors readily vent to avoid entrapment in the metal.
