Novel modular integration tool for surface coating of ceramic matrix composite material

Abstract

The invention belongs to the technical field of coating processing equipment, and particularly relates to a novel modular integration tool for a ceramic matrix composite surface coating. The tool comprises a tool body, a first clamp, a second clamp and a bolt. A plurality of mounting grooves are formed in the circumferential curved surface of the tool body, bolt grooves are formed in the bottoms of the mounting grooves and used for being connected with mounting bolts in a screwed mode, and the mounting positions of the bolts in the bolt grooves can be adjusted; the first clamp or the second clamp can be installed in the installation groove through bolts. By adopting the modular integrated tool provided by the invention, the size, the shape and the thickness of a composite material matrix sample can be flexibly adjusted, the spraying efficiency is greatly improved, the spraying process is simplified, the tool cost is reduced, and finally high-throughput preparation of the ceramic matrix composite material surface coating is realized.

Description

technical field [0001] The invention belongs to the technical field of coating processing equipment, in particular to a modular integrated tooling for the surface coating of a novel ceramic matrix composite material. Background technique [0002] At present, the service temperature and service performance of traditional superalloy materials are close to the limit, and it is difficult to meet the design requirements of a new generation of advanced aero-engines with high thrust-to-weight ratio and high efficiency. The temperature at the front inlet of the new generation of advanced aero-engine turbine reaches above 1400°C, which greatly exceeds the maximum temperature (1100°C) that the existing nickel-based superalloys can withstand. Continuous fiber-reinforced ceramic matrix composites have the advantages of high temperature resistance, low density, high specific strength, high specific modulus, and oxidation resistance. Due to the disadvantages of poor quality, it is widely...

Problems solved by technology

[0005] At present, the traditional coating spraying tooling can only clamp one or two kinds of substrate samples. If the size of the sample changes, the tooling needs to be redesigned

At the same time, the traditional spraying tooling is only suitable for fixed process parameters, spraying one type of coating, it is impossible to spray multiple coatings in a single time, and the spraying process is more cumbersome
