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: A method is disclosed enabling a technologically controllable and economical production of a hard-magnetic powder composed of a samarium-cobalt base alloy for highly coercive permanent magnets. The method is based on a HDDR treatment in which a starting powder is subjected to hydrogenation with disproportionation of the alloy in a first method step under hydrogen and, in a subsequent, second method step under vacuum conditions, a hydrogen desorption with recombination of the alloy. A starting powder containing samarium and cobalt is treated in the first method step either at a high temperature in the range of 500° C. to 900° C. and with a high hydrogen pressure of >0.5 MPa or by applying an intensive fine grinding at a low temperature in the range of 50° C. to 500° C. and with a hydrogen pressure of >0.15 MPa.

Abstract: The invention relates to the production or treatment of semiconductor or other solid components, especially to a method for directly nano-structuring amorphous carbonlayers. According to the invention, a local, field-induced reaction is activated in the carbon with an electrically conductive or semiconducting probe. Said probe is positioned at a distance from the amorphous carbon layer or is passed over said amorphous carbon layer at a distance. The distance must be such that the electrical conduction mechanism ‘field emission’ or ‘tunnelling’ can still occur. An electrical voltage is applied to said probe in relation to the layer at the points where recesses are to be made in the layer or the layer is to be removed. This process alone produces the desired structure without any further technical steps.
