Investigation of the Causes and Determination of Critical Mechanical Actions on Pins in Metal-Glass Articles Resulting in Loss-of-Tightness

Resumo

The results of an experimental study of the influence of twisting and bending forces on pins resulting in loss-of-tightness in sealed metal-glass articles (MGA) are reported. The critical values of the angles of rotation and bending of the pins at which glass begins to break are indicated. The technological features of MGA fabrication that increase the strength of a metal-ceramic seal are shown. The results are of interest for the manufacture of different hermetic relays and devices and explain the possible causes of the loss-of-tightness in devices.
