Supersonic plasma spraying system and method for nickel base alloy coating

Abstract

The invention relates to a supersonic plasma spraying system and method for a nickel base alloy coating. The supersonic plasma spraying system for the nickel base alloy coating comprises a supportingtable, a linear push rod is arranged on the supporting table, and the supporting table moves under drawing of the linear push rod. Tracks are arranged at the bottom end of the supporting table, and the supporting table moves in the track under the action of the linear push rod. A strip guide port is formed vertically in the supporting table, and a movable block is movably arranged in the strip guide port. Combined with other structures and methods, the supersonic plasma spraying system and method for the nickel base alloy coating effectively overcome defects that in the prior art, an electronically-controlled supersonic plasma spraying system is not easy to be changed in radian, insufficient in flexibility in the using process, difficult to take turning parts of an aluminum alloy part sprayed by the supersonic plasma spraying system into consideration in the nickel base alloy coating spraying process, and the performance of the nickel base alloy coating is poor.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy processing, and also belongs to the technical field of supersonic plasma spraying, in particular to a system and method for supersonic plasma spraying nickel-based alloy coating. Background technique [0002] Adding an alloying element to aluminum can change its structure and properties, making it suitable for various processing materials or casting parts. Alloying elements that are often added are copper, magnesium, zinc, and silicon. In this way, aluminum alloys are formed, and nickel-based alloys refer to a class of alloys that have comprehensive properties such as high strength and set oxidation and corrosion resistance at high temperatures of 650-1000 °C. [0003] In addition, in order to improve the anti-wear performance, supersonic plasma spraying system is usually used to spray nickel-based alloy coating on the surface of aluminum alloy parts, and spraying nickel-based alloy coatin...
