Plasma spraying silicon aluminum target coating rake

 

 

 

 

 

Plasma spraying silicon aluminum target coating rake

 

The process flow

Silicon aluminum powder - lining sandblasting - arc spraying base - plasma spraying - polishing processing - packaging

 

 

 

Brief introduction of main process:

 

Preparation of silicon aluminum powder: in order to ensure the stability of the process, it is necessary to purchase silicon ingots, aluminum ingots through grinding, screening, mixing and other steps to prepare silicon aluminum powder body for spraying.

 

 

Sandblasting process: the target liner purchased cannot be used directly. In order to make the spraying layer firmly combined, polishing sandblasting treatment is needed for the liner.

 

 

Arc spraying base: Spraying some alloy material as the transition layer between the coating and the liner, the function is to make the coating and the liner more stable connection. The base wire is made of nickel aluminum alloy.

 

 

Spraying process: this process is the main link of the whole production, target specifications are different, spraying time is long, the production capacity of a single spraying equipment is very limited, continuous more than 30 hours to produce a length of 3897mm target. Since the spray nozzle is a consumable part, it may be necessary to replace the spray nozzle several times during spraying.
