摘要： PROBLEM TO BE SOLVED: To provide thermal insulation coating and its construction method for preventing peeling-off of a ceramic layer by a simple configuration and to provide a turbine member on which the thermal insulation coating is applied and a gas turbine provided with the turbine member.
SOLUTION: A vertically cracked membrane is provided in a front fringe part 3a of a blade part 3, and the other part is an ordinary porous membrane. To explain concretely, the vertically cracked membrane is applied to a section shown by a diagonal line in Fig. a and shown by a scope A in Fig. b. It is in a scope of, for example, about 15 mm on a belly side from a front fringe and about 15 mm on a back side from a front fringe part root to an upper end. The porous membrane is applied to the other scope. The front fringe uses a line (not shown) on which, for example, a shower head (a cooling hole) of the front fringe part 3a is arranged in the longitudinal direction of the blade part 3 as a reference position.

摘要： PROBLEM TO BE SOLVED: To provide a local hardening method with which the toughness of a member (blade) body to a precipitation hardening type alloy-made member, such as a precipitation hardening type alloy-made steam turbine blade, is secured and only a portion which requires hardening (a portion needed to an erosion resistance) can be hardened.
SOLUTION: Only the portion which requires the erosion resistance in the precipitation hardening type alloy-made steam turbine blade 1, is locally heated to not less than the temperature of a solution treatment by using a heating means (laser beam, electron beam, high frequency induction or gas flame) to locally make the precipitation in the precipitation hardening type alloy into solution. Thereafter, only the portion which requires the erosion resistance is hardened by performing a heat treatment for aging-hardening under the conditions of the temperature and the time to increase the hardness than that before the local heating with the above heating means.

摘要： PROBLEM TO BE SOLVED: To secure a property of corrosion resistance, and also to prevent a thermal fatigue crack attendant upon the starting and stopping of an engine by padding a hot corrosion resistant alloy on a top face in multilayers, in this padding piston made up with an overlay on the top face in order to prevent high temperature corrosion in a piston touch-fire surface of a diesel engine. SOLUTION: A piston 1 is made up by a low chrome molybdenum steel containing, for example, less than 1 wt.% or so in chrominum and less than 0.5 wt.% or so in molybdenum, but in order to deter any high temperature corrosion in a piston touch-fire surface 2 of the piston 1, high nickel radical alloy steel, containing more than 58 wt.% in nickel, 20 to 23 wt.% in chromium and 8 to 10 wt.% in molybdenum is made padding in two layers over the whole surface of the top face of the piston 1. When thickness of the first layer 3 of the padding is set to t1 and thickness of the second layer 4 to t2 respectively, the upper limit of overlay thickness (t1 +t2 ) is determined in relation to useful frequency in order to prevent the occurrence of a thermal fatigue crack due to a temperature change cycle in the starting and stopping of an engine.

摘要： PURPOSE:To perform powder build-up welding with satisfactory strength without strain by sticking powder added with adhesive to a metal worn part by using a receiving die and drying and fixing said powder and afterward, depositing it on the worn part by a laser beam heat source. CONSTITUTION:The powder 2 which is formed by adding an adhesive to stellite powder is stuck along a lower surface recessed part of the receiving die 1 which is superposed on a moving blade 05 and the powder 2 added with adhesive is stuck to the build-up place. At the same time, the powder 2 added with adhesive is heated by a heater, etc., of the receiving die 1 and dried and fixed on the moving blade 05 and afterward, the laser beam heat source 3 is moved in parallel with the upper part of the front edge part of the moving blade 05 to perform the welding work and a build-up welded zone 4 is being formed. By this method, defects on the strength such as a pinhole do not occur on the joined part and the high strain is not caused and the firm powder build-up welding with few joining man-hours is performed.
