摘要： A method for laser shock peening an article including laser shock peening a first area (14) with at least one high fluence laser beam (16) and laser shock peening a border area (20) between the first area (14) and a non-laser shock peened area (22) of the article with at least one first low fluence laser beam (24). The border area (20) may be laser shock peened with a second low fluence laser beam (45) or more low fluence laser beams wherein the second low fluence laser beam (45) and others have a lower fluence than the first low fluence laser beam (24). The border area (20) may be laser shock peened with progressively lower fluence laser beams starting with the one first fluence laser beam (24) wherein the progressively lower fluence laser beams are in order of greatest fluence to least fluence in a direction outwardly from the first area through the border area (20) to the non-laser shock peened area (22).

摘要： PROBLEM TO BE SOLVED: To perform the controlling of a steel quality with which the diffusion speed of the carbon in the ferrite is restrained by using the strong magnetic field. SOLUTION: In the iron and the steel containing interstitial type solution element, it is controlled by applying the strong magnetic field to a phenomenon caused by diffusion phenomenon of the interstitial type element, further concretely, aging, dacarburizing. The lowering of the ductility caused by the aging at the time of drawing-process to the high strength high carbon steel wire rod, is restrained by using the strong magnetic field. Further, the decarburization in the ferritic zone in the case of low temperature rolling of the wire rod is restrained by rolling in the temperature zone of 500°C-Ae 3 transforming point, in the strong magnetic field having ≥1 tesla.

摘要： A durable part marking is achieved by local surface material modification. Selected surface area properties of the part are altered without substantial alteration of the physical configuration of the part (102). The alterations (106-114) are placed in a coherent pattern (104) accomplishing a durable method of identification marking on a part. Subsequently, the coherent pattern is detected and the coherent pattern interpreted to retrieve the original identification marking. Unlike labeling, ink marking, stamping or etching, many surface or near-surface modifications are not necessarily visible to the human eye. Hence, the invention includes: 1) a method for surface modification, 2) a method for assuring enhanced readability and accuracy of the read back of the encoded data, and 3) a method for locating the surface alteration.

摘要： A process and a device for the pulsed plasma strengthening of a metallic component, in which the surface to be strengthened is not acted on in a merely punctiform manner and the roughness of the surfaces is not adversely effected, comprising the steps of: providing a metallic component ( 1, 8, 18 ), coating a surface section ( 7, 7 ') of the metallic component ( 1, 8, 18 ) with a sublimable material ( 22 ), applying a pulsed plasma jet ( 20 ) to the surface section ( 7, 7 ') in such a way that the material is sublimed and as a result a shock wave is introduced into the component ( 1, 8, 18 ) in order to form residual compressive stresses in a region which extends from the surface section ( 7, 7 ') into the component ( 1, 8, 18 ).

摘要： PROBLEM TO BE SOLVED: To provide a laser shock peening method of a hard metallic parts such as a titanium alloy parts of a gas turbine engine. SOLUTION: The stationary laser beam of low output of about 3-10 Joule to be repeatedly pulsed for a relatively constant period is continuously emitted to a part 54 of an object 34 to evaporate a material of the emitted part. The surface material is evaporated with the pulse of a plurality of laser beam spots of about 1 mm in diameter to be formed by the laser beam on this surface, and a deep area with the residual compression stress extending into the object from the surface 54 to be subjected to the laser shock peening. Water flows like a curtain over the surface subjected to the laser beam while moving the object until the surface subjected to the laser shock peening is completely covered by the laser beam spots at least one time. The surface may be covered with a fusing coating suitable for generation of plasma.

摘要： PROBLEM TO BE SOLVED: To realize durability against fatigue damage by providing a laser shock peened surface extending along the front edge and/or rear edge of a blade, and a region having deep compressive residual stresses imparted by laser shock peening and extending into the blade from the laser shock peened surface. SOLUTION: A compressor blade 8 has a front edge part 50 extending along the front edge LE of an airfoil 34 from a platform 36 of the blade 8 to the blade tip 38. The front edge part 50 has a first width, and the front edge part 50 surrounds notches 52 and clefts that may be formed along the front edge LE of the airfoil 34. In order to oppose the fatigue damage of the blade 8 part, at least one of the pressure side 46 and suction side 48 is provided with a laser shock peened surface 54 and a prestressed region 56 having deep compressive residual stresses imparted by laser shock peening and extending into the airfoil 34 from the laser shock peened surface 54.
