Verfahren zur Herstellung von Kernen für den Feinguss.
摘要
Casting cores particularly useful in the investment casting industry are described. The cores are characterized by the presence of hollow ceramic particles, which facilitate the removal of the core from the casting they are used to form. In a preferred embodiment of the invention, the core is characterized by solid and hollow ceramic particles sintered to each other to form a core matrix, and such particles have the same composition. In an even further preferred embodiment, high temperature stable fibers are distributed uniformly throughout the matrix. <IMAGE>
