Abstract: PROBLEM TO BE SOLVED: To reduce a production cost and to improve productivity by using the laser beam irradiated from a machining head and conducting a marking process, a cutting process and a welding process. SOLUTION: For whole production processes consisting of a marking process, a cutting process and a welding process, laser beam machining is done by a common laser beam machine. Laser beam machining is not only in a high precision but has a machining speed greatly higher than conventional gas cutting, plasma cutting, TIG welding and MAG welding. Further, machining can do edge preparation as well to eliminate grinding. Because a heat input quantity is low and the deformation after machining is small, there is no need to straighten deformation. Further, generation of fume is suppressed as well. A working hour is greatly reduced to alleviate a worker load. By this method, one laser beam machine can conduct nearly all processes of an iron tank, etc., so that a production cost is greatly reduced and productivity is improved.

Abstract: PURPOSE: To prevent the peeling of a thermal barrier coating layer from an alloy member, at the time of providing the surface of a member made of a heat resistant alloy with a thermal barrier coating layer by ceramics via a bond layer by an alloy having a specified compsn., by forming an oxide barrier layer on the surface of the bond layer. CONSTITUTION: Since a moving blade and a stationary blade in a gas turbine are always exposed to an exceedingly high temp., they are formed of a heat resistant alloy 13 essentially consisting of Ni or Co, and on the surface, a thermal barrier coating layer 16 constituted of a ceramic excellent in heat resistance is formed via a bond layer 14 constituted of an alloy essentially consisting of at least either Ni or Co and moreover contg. Cr, Al, Y, Hf, Ta, Si or the like. In this constitution, the surface of the bond layer 14 is irradiated with a laser beam in an oxygen-contg. atmosphere to oxidize Al in the bond layer 14 and to form a melting layer 15 contg. dense Al2 O3 . By the presence of this melting treating layer 15, the arrival of oxygen in high temp. air to the bond layer 14 is prevented, and the peeling of the thermal barrier coating layer 16 made of ceramics from the member made of the heat resistant alloy is prevented.
