Description
Technical field
The present invention relates to technical field of mechanical processing more particularly to a kind of effective GH4169 alloys of microwave plasma torch
Turning process.
Background technique
Microwave plasma torch pipe is a kind of device for being excited using microwave tube and generating plasma flare.A kind of typical case
Microwave plasma torch pipe include a generation microwave energy magnetron (or other vacuum microwaves such as travelling-wave tubes, klystron
Device), the waveguide transmission system of a set of transmission microwave energy and it is a set of by microwave energy be added on working gas so as to generate etc. from
The excitation apparatus of sub- torch.In the excitation device, working gas starts to decompose after receiving microwave energy, a part of work
Make gas transition into plasma i.e. atom, atomic group, ion and electronics coexisting mixture, these mixtures are in the form of torch
It shows.
Microwave plasma torch pipe can generate high temperature when working, and the various catagen speeds of material are all accelerated under hot environment,
In use easily occur that tissue is unstable, is deformed at temperature and stress and crack growth, material surface
The defects of oxidation corrosion.Therefore, it is necessary to the components using material resistant to high temperature production plasmatorch part.
GH4169 alloy is a kind of high temperature alloy, is usually used in high temperature resistant, in corrosion resistant plasma flue purification device.
