Method for producing a strike sounding body |
摘要 |
<p>The method involves casting a preform in a mold with specific cooling speed, to obtain an amorphous state of a utilized metal glass and to integrate functional parts, with the preform, utilized during installation of the preform on an electro-erosion machine. A shape of an obtained metal glass striking gong (12) is cut by a wire electro-erosion technique, with drive speed that is regulated to limit heating of a part and to limit recrystallization of a surface layer of the striking gong, where the striking gong is in the form of circular metal bar.</p> |
