Abstract: In an apparatus and a method for marking glass with a laser, the glass is first brought to a temperature above the transformation temperature of the glass. The glass is then acted upon by a laser pulse which produces a mark on the surface of the glass. The peak power of the laser pulse is preferably selected so that it is merely a thermal interaction with the glass surface which occurs. This has the advantage that the material properties of the marked glass remain unchanged compared with the unmarked product.

Abstract: A method for producing apertures in hot section components of gas turbine engines made from ceramic matrix composites that have at least one oxidizable component. The method involves forming the apertures using a laser beam controlled by parameters that ablate the ceramic matrix composite in the path of the beam, while simultaneously heating the matrix material, SiC or SiN, to a sufficient temperature to oxidize it to form a silica. Sufficient heat is supplied by the beam to melt the silica to cause it to flow. The melted silica is quickly solidified as recast silica along the walls of the newly created aperture before it has an opportunity to flow and form undesirable geometries. The wall of the aperture is formed of recast silica that is a smooth surface and that forms an oxidation barrier to inhibit any further oxidation of the underlying composite as it is exposed to the high temperatures and oxidative, corrosive atmosphere of an operating gas turbine.

Abstract: A method is described for uphill casting in sand molds with high-resin casting cores or especially casting cores containing binders, and with directed solidification of metallic castings that have at least one cavity. In particular, these are prototypes of engine blocks or cylinder heads, for example for internal combustion engines that are provided with a cavity through which coolant water flows. To provide for low-turbulence flow of the liquid molten metal during the deaeration of the casting mold, the casting mold is provided with at least one feeder head that is connected through a casting system to an infeed funnel, and the molten metal it contains is displaced by gravity through the casting system into the casting mold, with the cavity in the molten metal being subjected after the filling to reduced pressure that is greater than the pressure of the core gases formed in the core. This eliminates the hindrance to filling the mold from air pockets in the mold.
