摘要： A repair system for in-situ repair of a machine. The repair system includes a laser unit configured to emit a laser beam, a galvanometer optically coupled to the laser unit and configured to adjust the laser beam received from the laser unit, a source of a flexible metallic mesh, a delivery unit configured to receive the flexible metallic mesh from the source of the flexible metallic mesh, and a controller communicably coupled to the laser unit, the galvanometer, and the delivery unit. The controller is configured to control the delivery unit to deposit the flexible metallic mesh on a surface of the machine. The controller is further configured to control the laser unit to emit the laser beam and to control the galvanometer to adjust the laser beam in order to weld the flexible metallic mesh to the surface of the machine, thereby forming a repair patch.

摘要： An apparatus for coating a surface of a substrate includes an evaporant source disposed within an open environment including air at atmospheric pressure. The evaporant source includes a coating material. The apparatus further includes an energy beam source disposed within the open environment and configured to emit at least one energy beam that impinges on an emission region of the evaporant source to form a vapour plume at the emission region. The vapour plume includes the coating material of the evaporant source. The apparatus further includes a fixture configured to position the evaporant source relative to the substrate within the open environment, such that a maximum distance between the emission region of the evaporant source and the surface of the substrate is less than or equal to 10 cm.
