摘要： Method for vacuum depositing corrosion and oxidation resistant alloy coatings on turbine buckets having leading edges and trailing edges, with simultaneous rotation of the turbine buckets about their longitudinal axis in a vapor stream above a vapor source. The time of stay of each element of the surface above the vapor source is varied during a 360.degree. rotation such that it is shortest when the leading edges and the trailing edges are pointed towards the vapor source and longest when the concave and convex flanks are presented to it.

摘要： Melting furnace (1) for the production of strand-cast ingots (17, 18) in a protective gas atmosphere, has a charging apparatus (8) for feeding starting material (11) into a melting area (14). Within a melting chamber provided with a chamber floor (2d) and at least one energy source (4,5) there is situated a strand-casting mold (15) for the transformation of the melt to an ingot (17, 18) and underneath the strand-casting mold is disposed an offbearing apparatus (25) for offbearing the ingot, and an offbearing chamber enveloping the ingot and the offbearing apparatus. To solve the problem of operating such a melting furnace virtually continuously, the strand-casting mold (15) together with at least one additional strand-casting mold (16) is disposed in the chamber flow (2d) in such a manner that each of the strand-casting molds (15, 16) can be brought into the drop path of the melt by a preferably horizontal relative movement. Furthermore, one offbearing apparatus (25, 26) and one offbearing chamber (23, 24) are associated with each strand-casting mold, and at least one vacuum valve (19, 20) is disposed between each strand-casting mold (15, 16) and the offbearing chamber (23, 24) associated with it. Preferably the strand-casting molds (15, 16) are disposed in a chamber floor (2d) configured as a turning disk.

摘要： Metal particles are remelted in a fusion zone by electron beam bombardment and formed in a continuous casting mould. Furthermore,(a) the metal particles are evenly distributed over the horizontally positioned floor of a fusion ladle,(b) the metal particles are joined together into a plate-shaped structure by means of the electron beam, whereafter(c) the floor of the fusion ladle is moved into a position inclined in relation to the horizontal,(d) the electron beam is guided upwards over the sloping, plate-shaped particle structure so that this is firstly preheated and fused directly thereafter, while(e) the molten metal running over the lower part of the floor is simultaneously kept liquid by electron beam bombardment, whereafter(f) the electron beam is guided back downwards over the sloping floor of the fusion ladle, and(g) the floor of the fusion ladle is returned to the horizontal starting position and is once again charged with metal particles according to feature (a).

摘要： High-purity metal powder is made by the electron beam melting of a starting material in rod form in a vacuum wherein the molten metal is momentarily caught on a spinning plate rotating at high speed and flung therefrom and thereafter solidified by cooling. The metal on the spinning plate is bombarded with an electron beam that is so focused and periodically deflected that its focal spot is many times smaller than the diameter of the spinning plate. The beam deflection between the rotational center of the spinning plate and its marginal area is performed such that the spinning plate is scanned in a zone that extends radially of the axis of rotation of the spinning plate and is small in relation to its diameter. Cooling of the metal particles to the point of solidification is accomplished by radiation loss.
摘要翻译：通过在真空中以棒状的原料电子束熔融形成高纯度金属粉末，其中熔融金属被瞬间捕获在高速旋转并从其中溅出的纺丝板上，然后通过冷却固化。纺丝板上的金属被电子束轰击，电子束如此聚焦并周期性地偏转，使其焦斑比纺丝板的直径小许多倍。进行纺丝板的旋转中心与其边缘区域之间的梁偏转，使得纺丝板在纺丝板的旋转轴线的径向延伸的区域中扫描，并且相对于其直径小。将金属颗粒冷却至凝固点是通过辐射损失来实现的。

摘要： Method for evaporating melts of alloys of metals of different vapor pressures from continuously fed, large-area evaporating crucibles by direct bombardment of the bath surface with focused electron beams which are periodically deflected according to a pattern. The alloy material is deposited on a plurality of substrates such as turbine blades which are positioned in a field above the evaporating crucible with local adaptation of the energy density to the thermal economy of the melt bath. At least one electron beam is deflected onto at least two substantially rectangular beam fields and is guided in each of these fields through a line raster at a frequency of at least 100 Hz while shifting periodically from one to the other field with a shift frequency of at most 5 Hz.
