摘要： A method for making or repairing a gas turbine engine component includes the step of directing a pulsed ultra-violet laser beam on a location of a film cooling hole after application of a thermal barrier coating to athermally remove any coating material which may be obstructing the cooling hole without damaging the engine component or removing any of the coating from the surface of the component around the cooling hole.

摘要： In laser plasma coating, the feeding of the material to be applied is unsatisfactory. Too much material is blown away and not used for the coating. Moreover, the application is inhomogeneous, depending upon the direction in which the laser beam is moved. According to the invention, the material is introduced at an angle coaxial with the laser beam and the angular momentum is then braked at the latest at the position where the powder leaves the feed head.

摘要： An oversize compact blank having a surface and edges that establish it as oversized is provided. A chip breaker pattern is formed on the compact blank surface. Preferred means for forming the chip breaker pattern include use of a laser, a plunge EDM apparatus, or by ultrasonic abrading. Thereafter, the edges of the patterned oversized compact blank are finished to reduce the size of the blank. When pluge EDM apparatus fitted with a patterned plunger is used, the compact blank must be electrically conductive.

There is a fork which is seated in parallel elements whereby to this fork by means of handle and fixator is fastened a slide with longitudinal channels and a plate for axial inclination per 15.degree.. To this slide is fastened a second electric motor, and on its axis is mounted a bearer on which is fastened a mask in which is fixed the item to be decorated. On the rotating bearer is fastened a disk on which are mounted 4 spokes with 4 springs and a replaceable stand.

摘要： A process for drilling chamfered holes includes the steps of directing noncontact energy onto the outer surface of the part to form a recessed crater-like entrance with chamfered walls and thereafter directing a small diameter wire electrode adjacent the substrate and spark eroding the base without removing material from the chamfered walls so as to produce a combined passage through the part with a chamfered entrance leading to a smaller outlet. In one embodiment the part has a ceramic coating which is initially removed from the part by either focusing a laser beam to a penetration depth which removes the ceramic coating while forming the entrance and in another embodiment the coating is initially removed by imposing a high voltage pulse thereagainst from a spark erosion electrode of electrical discharge machining equipment.

摘要： A method for attaching a diamond component to metal is described, wherein a layer of brazing material is provided at the interface between the diamond and the metal. A laser is used for heating the brazing material. The laser beam is focussed through the diamond at least substantially on the interface between the diamond and the metal. In one aspect, the invention is utilized in the manufacture of a travelling wave tube having a metal helix disposed within the tube. Diamond support blocks are bonded between the inner walls of the tube and the windings of the helix according to the method of this invention.
