Method for laser cladding thermally insulated abrasive particles to a substrate, and clad substr |
September 26, 1995 |
| A method of applying abrasive materials to a substrate includes the steps of forming a relatively small pool of superheated molten metal at the surface of the metal substrate by creating an interaction area on the substrate with a localized high energy source. A powder system is injected |

Process for welding nickel-based superalloys |
February 14, 1989 |
| A process for preventing crack formation in nickel alloy substrates having a gamma-prime phase includes providing a substrate comprised of a nickel alloy having a gamma-prime phase. A portion of the substrate is irradiated with a laser beam and thereby forms a molten pool of the alloy. A |

Back reflection monitor and method |
October 11, 1988 |
| A beam monitor comprises a mirror for reflecting an incident beam of radiation to a target and for receiving a reflected beam from the target and has a surface on which the beams impinge. Incident and reflected beam channels are orthogonally disposed within the mirror. Each of the channe |

Laser spray nozzle and method |
February 9, 1988 |
| A laser spray nozzle assembly includes a nozzle body with first and second spaced apart end portions. A beam passageway extends between the end portions and permits a laser beam to pass therethrough. A housing surrounds the second end portion. The housing is spaced from the second en |

Electromagnetic radiation detectors |
November 3, 1987 |
| A predetermined characteristic of a laser beam is detected by disposing a reflector (11) in the path of the beam and coupling an electromechanical transducer (12) to the reflector to detect a mechanical response of the reflector to the incident beam. |
