Beschreibung
Zusammenfassung:	A method of coating a surface comprising providing a source of amorphous metal that contains manganese (1 to 3 atomic %), yttrium (0.1 to 10 atomic %), and silicon (0.3 to 3.1 atomic %) in the range of composition given in parentheses; and that contains the following elements in the specified range of composition given in parentheses: chromium (15 to 20 atomic %), molybdenum (2 to 15 atomic %), tungsten (1 to 3 atomic %), boron (5 to 16 atomic %), carbon (3 to 16 atomic %), and the balance iron; and applying said amorphous metal to the surface by a spray. L'invention concerne un procédé de revêtement d'une surface qui consiste à utiliser une source de métal amorphe contenant du manganèse (1 à 3 % atomique), de l'yttrium (0,1 to 10 % atomique) et du silicium (0,3 to 3,1 % atomique) dans la plage de la composition indiquée entre parenthèses; ainsi que les éléments suivants dans la plage spécifiée de la composition indiquée entre parenthèses: chrome (15 à 20 % atomique), molybdène (2 à 15 % atomique), tungstène (1 à 3 % atomique), bore (5 à 16 % atomique), carbone (3 à 16 % atomique), l'équilibre étant apporté par le fer. Le procédé consiste ensuite à appliquer ledit métal amorphe sur ladite surface par pulvérisation.
