Problems solved by technology

Due to the lack of grain boundary strengthening elements in common nickel-based superalloy blade materials, once the grain boundary, especially the grain boundary perpendicular to the main stress axis of the blade, is formed, it is easy to cause crack initiation and propagation at the grain boundary under stress, which seriously threatens the blade. service safety

Abstract

The invention discloses a system used for restoring a single crystal or oriented crystal alloy blade. The system comprises a welding torch and an assorted device thereof, a blade motion device, a restoration material feeding device, a thermal control device, a protection cabin device and a system used for restoring path planning; the blade motion device is arranged at the bottom inside the protection cabin device, the welding torch and a welding torch of the assorted device are arranged at the portion, corresponding to the blade motion device, of the upper portion, and the restoration materialfeeding device is arranged at the side of the welding torch; the blade motion device is provided with a sensing heating coil controlled by a heating control device. All the devices are synergeticallycooperated to automatically and efficiently restore a blade to be restored, the restored and subsequently machined blade meets blade service requirements, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of blade repair equipment, and in particular to a system for repairing single crystal or oriented crystal alloy blades. Background technique [0002] The technical level of aero-engines is an important symbol to measure a country's comprehensive scientific and technological level, industrial basic strength and comprehensive national strength. The performance indicators of aero-engines directly determine the performance of aircraft. As an important component of aero-engines and ground-based gas turbines, the comprehensive performance of blades, such as service temperature and service life, seriously restricts the progress of aero-engine technology. At the same time, due to the extremely harsh working environment of aero-engines or ground gas turbines, blades are prone to defects such as wear, corrosion, cracks, and material loss when they work for a long time in an environment of high temperature, high pressure, and co...
