Abstract:
The present invention relates to composition comprising a blend of at least one boron source and at least one silicon source, and the composition further comprises particles selected from particles having wear resistance properties, particles having surface enhancing properties, particles having catalytic properties or combinations thereof, wherein the blend comprises boron and silicon in a weight ratio boron to silicon within a range from about 3:100 wt:wt to about 100:3 wt:wt, wherein silicon and boron are present in the blend in at least 25 wt%, and wherein the at least one boron source and the at least one silicon source are oxygen free except for inevitable amounts of contaminating oxygen, and wherein the blend is a mechanical blend of particles in and the particles have an average particle size less than 250 µm. The present invention relates further to a method for providing a coated product and a coated product obtained by the method.
Abstract:
An apparatus includes a prism mount that retains a prism. The mount includes a ledge that engages a first side of the prism, a support surface structured that engages a second side of the prism, a retaining member that slidably engages a third side of the prism, and a biasing member that biases the retaining member to an engaged position with the prism. The mount further includes a slot disposed between the ledge and the support surface. The retaining member includes a machine screw, and a nut confines the biasing member between the nut and a prism mount body. The biasing member is retained in a counterbore in the prism mount body, and an end of the machine screw protrudes from the counterbore. The prism mount body further includes an alignment slot at a fixed azimuthal angle, and the laser deposition device includes a protrusion that engages the alignment slot.
Abstract:
Der Düsenkörper umfasst ein erstes Düsenkörperteil (1) und ein zweites Düsenkörperteil (3) . In dem ersten Düsenkörperteil (1) sind eine erste Düsennadelausnehmung (10) zur Aufnahme einer Düsennadel (15) und ein erster Führungsbereich (8) für die Düsennadel (15) ausgebildet. In einem ersten Verfahrensschritt wird das erste Düsenkörperteil (1) mit dem zweiten Düsenkörperteil (3) montiert. Ferner wird Hartlot mit einer Arbeitstemperatur im Bereich der Härtetemperatur des ersten Düsenkörperteils (1) einem Montagebereich (5) zugeführt. Der Montagebereich (5) bildet sich zwischen dem zweiten Düsenkörperteil (3) und dem ersten Düsenkörperteil (1) aus. Das montierte erste Düsenkörperteil (1) und zweite Düsenkörperteil (3) wird einem Härtevorgang unterzogen, während dessen die Härtetemperatur des ersten Düsenkörperteils (1) erreicht wird.
Abstract:
A process is provided for welding a nickel or cobalt based superalloy article to minimize cracking by preheating the entire weld area to a maximum ductility temperature range, maintaining such temperature during welding and solidification of the weld, raising the temperature for stress relief of the superalloy, then cooling at a rate effective to minimize gamma prime precipitation.
Abstract:
The present invention relates to a method for treating functional surfaces, i.e. surfaces determining tolerance and position accuracy, on objects (26) of metal, hereafter named matrix material. The invention is characterised in that the functional surfaces are obtained by melting certain areas of the surface layer of the object with high energy and simultaneous supply of additive (28) comprising wear resistance increasing material.
