Abstract: The aim of the invention is to develop a method for producing massive-amorphous layers on massive metallic shaped bodies. According to the method, amorphous layers having a thickness of >20 &mgr;m can be produced in only one procedure step. To this end, alloys which can be used for producing massive metallic glasses under quick solidification conditions or alloy elements which can be used for producing massive metallic glasses together with the elements of the shaped body material and under quick solidification conditions are molten by means of high-energy radiation are directly applied onto the massive metallic shaped body for producing an amorphous layer that is >20 &mgr;m up to several millimeter thick or are alloyed into the surface of the shaped bodies. The melt is quickly solidified by means of natural cooling and/or forced air cooling of the shaped body. The inventive method enables to coat metallic shaped bodies with massive metallic glasses which improve the surface characteristics.

Abstract: After the pressure of the gas in a first chamber reaches the maximum value, the cover for the air bag is broken up. The cover is broken at the pressure of the maximum value, and there is almost no waste of the gas energy. Thus, the cover can be broken up by the small amount of the gas energy and the heat losses are extremely reduced, so that the amount of the gas generating agents are made small. Also, the cover is broken by the burning of the first chamber and the air bag is inflated at the first stage by expansion and inertia of the gas. There is provided a mechanical timing for ignition delay, and then the bag is fully inflated by the burning of a second chamber. Therefore, the bag can be desirably inflated.
