摘要： A process for forming a durable, resistant oxide coating on zirconium metal or zirconium-based alloys, in which the metal or alloy is heated either rapidly to a predetermined temperature in an oxidizing or non-oxidizing environment or heated rapidly or slowly in an environment substantially devoid of an oxidizing agent until the predetermined temperature has been reached. The base metal can be pure zirconium or a zirconium-based alloy having niobium and/or titanium. The temperature, oxygen level, and time of exposure are controlled to elicit the desired properties. The oxidized specimen is then cooled under controlled conditions to further control the thickness and hardness of the oxide layer.

摘要： A cladding tube, a fuel rod and a fuel assembly are disclosed. The cladding tube comprises a tubular base component having an outer surface and an inner surface defining an inner space of the cladding tube housing a pile of fuel pellets. The tubular base component is made of a Zr-based alloy. A coating is applied onto the outer surface for protecting the tubular base component from mechanical wear, oxidation and hydriding. The Zr-based alloy has the following composition: Zr=balance, Al=0-2 wt %, Ti=0-20 wt %, Sn=0-6 wt %, Fe=0-0.4 wt %, Nb=0-0.4 wt %, O=200-1800 wtppm, C=0-200 wtppm, Si=0-200 wtppm, and S=0-200 wtppm. The total amount of Al+Ti+Sn>2.5 wt % and ≤28 wt %.

摘要： The invention relates to a method for producing a component from an at least partially amorphous metal alloy, comprising the following steps: providing a powder from an at least partially amorphous metal alloy; producing a shaped semi-finished product from the powder in that the powder is applied in layers and the powder particles of each newly applied layer, at least at the surface of the semi-finished product to be shaped, are fused and/or melted by targeted local heat input and bond to one another as they cool again; and hot pressing the semi-finished product, wherein the hot pressing is performed at a temperature that is between the transformation temperature and the crystallisation temperature of the amorphous phase of the metal alloy, wherein a mechanical pressure is exerted onto the semi-finished product during the hot pressing and the semi-finished product is compacted during the hot pressing.The invention also relates to a component produced by such a method from a powder formed from an at least partially amorphous metal alloy and to the use of such a component as a gearwheel, friction wheel, wear-resistant component, housing, watch case, part of a gear unit, or semi-finished product.
