| Research Abstract |
Die casting has been said to be effective production method from a yield rate point of view. Therefore as copper alloys or aluminum alloys, this method is widely used. But as ferrous alloys, their melting point are relatively high and die, container and sleeve are short-lived, this method does not come into wide use.
In this study, in order to extend the die casting to ferrous alloys, ceramic materials for die, container and sleeve are developed and their machining proce sses are experimentally studied. Results obtained are as follows.
(1) Silicon nitride, silicon carbide and carbon fiber reinforced alumina are suitable as die, container and sleeve materials.
(2) Laser annealing, irradiating YAG laser light on ceramic surfaces, can remove pores and can get plain surfaces.
(3) Single crystal diamond tool wears beavily during cutting ceramics. But PCD diamond deposited from gas phase is long-lived.
(4) Vitrified bonded diamond wheel used borosilicate glass as binding material has sufficient grinding performance to process these ceramic materials.
