摘要： PROBLEM TO BE SOLVED: To improve inspection performance by applying a paint with sufficiently high absorption rate and thermal conductivity of light energy for eliminating disturbance due to surface soil or the like to the surface of an inspection target and then heating the surface for inspection. SOLUTION: Paint 70 with a high absorption rate of light energy and thermal conductivity is applied to the outer surface of a target 72 to be inspected. A cavity 73 existing in the target 72 to be inspected and a surface contamination part 74 existing on the outer surface of the target 72 to be inspected before applying the paint 70 is present at the inside. When the target 72 to be inspected is heated by a heater from the surface, the difference in the absorption rate of light energy disappears between the surface soil part 74 due to the paint 70 and the other parts even if the surface soil part 74 exists on the outer surface. Also, heat by the light energy is also conducted efficiently through the target 72 to be inspected, the temperature of a part where the surface soil part 74 exists becomes the same as that of the other parts, disturbance caused by it is eliminated, and the cavity 73 can be clearly detected.

摘要： PURPOSE:To obviate the generation of crack, fissure and deformation at the time of removing a binder from a molding molded from powder for sintering and binder by heating up the molding. CONSTITUTION:This binder removing method for the molding has a stage for placing the infection molding 1 formed by mixing the powder for sintering and the binder and injection molding the mixture, via alumina powder 3, onto a support 2 formed to comply with the shape of the injection molding 1 and a stage for putting the injection molding 1 into an electric furnace and heating up the molding. The alumina powder absorbs the binder and acts as the ways for escape of binder separating gases and, therefore, good degreasing is possible without generating the crack, etc. Further, the molding is held via the alumina powder and is, therefore, not deformed and is kept free from the shearing force and tension arising from expansion and contraction.

摘要： PROBLEM TO BE SOLVED: To carry out coating removal by acid pickling by releasing residual stress while preventing stress corrosion cracking and deterioration in the strength/ductility of a base material.
SOLUTION: A moving blade 1 formed of γ' phase precipitation strengthened Ni-base alloy has an oxidation-resistant coating on the surface. In order to carry out recoating, heating is performed at 975 to 1,050°C in an annealing furnace 2 to make both Cr
23 C
6 type carbides and (Ti, Nb)C type carbides enter into solid solution and reduce the amount of these carbides present and then heating is performed at 1,050 to 1,250°C at which residual stress can be relieved and initial melting does not occur to relieve the residual stress. Because the coating is removed by carrying out acid pickling using hydrochloric acid 4 in a state where the carbides are eliminated and the residual stress is relieved, the occurrence of stress corrosion cracking can be prevented.
