Step (e) uses supersonic speed cold low cold spray apparatus spray metal, such as nickel, copper, cobalt, the metal of spraying to be formed
Coating layer thickness be 0.2mm~0.3mm, uniform coating thickness, flawless.
In original structure, carbon plate surface smoothness is poor, stomata is more, with copper coin surface formed point contact, contact resistance compared with
Height causes contact surface fever higher, and then generates thermal stress.The presence of slot and chamfering has ensured the sprayed metal layer and carbon plate
The higher engagement fastness in surface, spray metal layer thickness are 0.2mm~0.3mm, can be occurred during bolt is firm certain
Flexible deformation, be substantially better than in brittle carbon plate to contact with copper coin, and metal layer conductivity can led far above carbon plate
Under logical operating mode, electric current is preferentially distributed in metal layer, and then is uniformly conducted to carbon plate end, and current distribution is more reasonable, contact electricity
Smaller is hindered, to reduce calorific value, reduces thermal stress suffered by carbon plate.Meanwhile the presence of metal layer reduces fluorine gas and fluorine significantly
Change corrosion of the hydrogen to carbon plate connecting pin.The improvement of these two aspects is conducive to extend the service life of carbon plate.
