Abstract

L'invention porte sur un verre ultramince à haute résistance et sur un procédé de préparation s'y rapportant. Le verre ultramince à haute résistance comprend un substrat en verre. Au moins une couche de revêtement à contrainte est fixée à la surface du substrat en verre. Un coefficient de dilatation de la couche de revêtement est différent de celui du substrat en verre. À l'aide d'un mode d'application de revêtement et de l'utilisation de la différence des coefficients de dilatation du substrat en verre et de la couche de revêtement, la couche de revêtement a une déformation par rapport au substrat en verre lorsqu'un film est formé sur la surface du substrat en verre, de façon à former une autre contrainte uniformément répartie sur la surface du substrat en verre; la contrainte peut à nouveau augmenter la résistance du verre et également réduire l'importance de la déformation du verre lorsque le verre subit un choc, ce qui fournit de cette manière un apport complémentaire pour à nouveau augmenter la résistance du verre renforcé.
