Tensions in optical glass from the thermoelectric impact of electronic flow

Tensions in optical glass from the thermoelectric impact of electronic flow

Abstract

The character of the residual stress in the surface layer of the optical glass plates K8, which result from thermoelectric effects in electron beam processing of the surface was defined. Residual stresses in the surface layer of optical glass is characteristic result of the thermoelectric action on the material the electron beam (as in the formation of a liquid phase in the surface layer, both with and without it). It is shown that the strength of the modified surface layer of glass depends on the cooling mode. The mechanism of residual stresses is used for directed exfoliation of the surface-modified layer in the form of plates required shapes.

Визначено характер залишкових напружень у поверхневому шарі (ПШ) пластин з оптичного скла К8, які виникають у результаті термоелектричного впливу при електронно-променевій обробці поверхні. Залишкові напруження у поверхневому шарі оптичного скла є характерним результатом термоелектричної дії потоку електронів на матеріал (як при утворенні рідкої фази у ПШ, так і без неї). Показано, що міцність модифікованого ПШ скла з залежить від режиму охолодження. Механізм залишкових напружень використано для спрямованого відшаровування ділянок модифікованого ПШ у вигляді пластин необхідної форми.
