Abstract

The invention provides a 1050°C-resistant supercharger nozzle ring blade nickel-based alloy material and a manufacturing method thereof, including C, Mn, Si, S, P, Cr, Fe, Al, Ti, B, Co, Cu, Nb and Ni; based on the mass of the nickel-based alloy material of the blade, the content of C is 0.5-1.0%, the content of Mn is 1.00%, the content of Si is 1.00%, and the content of S is 0.015%. , the P content is 0.02%, the Cr content is 18.0-21.0%, the Fe content is 1.00%, the Al content is 1.5-2.5%, the Ti content is 1.0-2.0%, and the Co The content is 5.0-8.0%, the Cu content is 0.20%, the Nb content is 1.5-2.5%, and the balance is Ni. The VGT blade of the present invention has reduced processing difficulty. After 400h exhaust temperature of 980°C engine reliability test, the blade is intact without deformation after the test, the thickness of the blade oxide layer is less than 10 μm, the increase of the shaft hole matching clearance is less than 100 μm, and the blade shaft and the mounting plate The amount of wear of the shaft hole is within an acceptable range.

Description

technical field [0001] The invention belongs to the field of alloy metals, and in particular relates to a 1050°C-resistant supercharger nozzle ring vane nickel-based alloy material and a manufacturing method thereof. Background technique [0002] Variable geometry turbocharger nozzle ring (hereinafter referred to as VGT) blades (see figure 1 , referred to as VGT blades) are guide vanes, whose function is to change the direction and speed of engine exhaust entering the turbocharger under the control of the linkage mechanism. With the development of technology, people have more and more stringent requirements for automobile engines, not only must have strong power, but also must have extremely high efficiency and sufficiently clean emissions. This requires the engine to achieve its most efficient working state under various working conditions, so it is necessary to meet the requirements of the engine for the intake air volume under various working conditions. This requires t...
