Another object of the present invention is to provide above-mentioned aluminum alloy casing band boss inner wall local plasmas to spray NiCrAlY
Application of the method for coating in manufacture aero-engine.
The present invention solves its technical problem and adopts the following technical solutions to realize.
The present invention proposes a kind of method of the aluminum alloy casing with boss inner wall local plasma spraying NiCrAlY coating, packet
It includes: oil removal treatment being dusted to casing, then non-spraying region is protected, it is thick to carry out surface sanding to area to be sprayed
Change processing, is put into fixture for casing and is fixed on turntable, sprays NiCrAlY coating to area to be sprayed.
In spraying process, when the temperature of area to be sprayed is more than 150 DEG C stop spraying, to temperature be down to 100 DEG C with
Under be further continued for spraying, so repeat, until thickness meets the requirements.
Method the invention proposes above-mentioned aluminum alloy casing with boss inner wall local plasma spraying NiCrAlY coating
Application in manufacture aero-engine.
The beneficial effect comprise that
The present invention ensure that the temperature control of spraying process well, effectively controls the deformation extent of casing, passes through tune
Whole sanding technological parameter and spray parameters ensure that the coating quality of crossover position between boss and area to be sprayed, coating are processed into
Product rate is high, meets running requirements.Spraying obtained coating can play the role of obturaging, and have preferable antioxygenic property, coating
