摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of a rotor with improved durability and reliability, by enhancing strength of a brazing joint part between a wheel and a shaft without increase in manufacturing man-hours, and to provide a turbine rotor for an exhaust turbocharger, in a brazing type rotor formed by brazing a wheel and the shaft. SOLUTION: In the manufacturing method for a rotor, the wheel in which blades are formed to an outer circumference of a disc part is joined with the bar-like shaft by brazing to constitute the rotor. A joint surface of the wheel and a joint surface of the shaft are arranged to be opposed to each other through brazing filler metal in a heating furnace, and infrared rays are emitted on a wheel side part to heat the joint face at 1000-1080°C and melt the brazing filler metal, and thereby the joint surfaces of the wheel and the shaft are joined with each other.

摘要： PROBLEM TO BE SOLVED: To improve reliability against a high temperature strength of a joining part by joining a turbine wheel composed of TiAl alloy and a steel shaft, using an alloy as an intermediate member whose thermal expansion coefficient is equivalent to that of the TiAl alloy. SOLUTION: When a steel made shaft 2 is joined with the TiAl alloy made turbine wheel being composed of and including, at an atomic ratio, 45-48% Al, 5-9% Nb, 1-2% Cr, 0.2-0.5% Si, 0.3-2% Ni, 0.01-0.05% Y and, Ti and an avoidable impurity as a balance, an intermediate material 3 composed of an incoloy 903, 907 or 909 is used. A concave part is formed on either one part of the joining faces between the turbine wheel 1 and the intermediate member 3, and a convex part is formed on the other face part. An abrasion welding is then carried out under the condition that the concaved and convexed parts are abutted. The joining face shape is made in a manner that the central part, which being equivalent to 20-70% of cross section diameter being orthogonal to the shaft, is vertical against the shaft and its outer surrounding is slanted by 20-40 deg., preferably 30 deg. from the face vertical against the shaft.
