With the increase of thrust-weight ratio of aero-engine, the working temperature of core parts
is becoming higher and higher. In order to improve the service life of core parts, many high …

To achieve more uniform gas film and higher working temperature, the design of film holes
on combustion section parts of aero engine is developing towards three trends: smaller …

With the rapid development of the information age, electronic components are developing
toward miniaturization, which makes the manufacturing of chips more and more difficult …

Inconel 718 offers high oxidation resistance, mechanical strength, and heat resistance,
which enables turbofan engines to maintain excellent performance in an operating …

The hot section parts in a gas turbine are subject to high working temperatures and
mechanical forces. In order to endure the harsh conditions, these parts are generally made …

A novel method of laser machining combined with high temperature chemical etching
(LMHTCE) was proposed. This novel method can take full advantage of both approaches to …

Laser drilling of high-aspect-ratio holes is gradually on the agenda in the field of aerospace
manufacturing. We present a comparative study of high pulse energy femtosecond laser …

Effusion cooling holes are commonly drilled in nickel super-alloy aero-engine components
using electro-discharge machining (EDM) or pulsed laser drilling. While drilling quality of …
