TARGET FOR APPLYING FUNCTIONAL COATINGS AND METHOD FOR MAKING IT Russian patent published in 2007 - IPC C23C14/36 B22F3/105 

FIELD: powder metallurgy, namely target for applying functional coatings and method for making it, possibly in chemical, machine tool manufacture industry branches, in machine engineering and metallurgy.

SUBSTANCE: at least three tablets are shaped for forming working dispersed layer, intermediate layer and initiating layer at least of three powder mixtures of exothermic compositions. Said tablets are placed layer by layer onto profiled metallic through layer of metallic solder charge. In initiating layer process is started due to action of which metallic solder and metallic filler being component of powder mixture at least of one layer are melted. Then said layers are subjected to pressure action by pressing in 2 - 10 s after completing said process for time period no less than 5 s. In the result working dispersed layer and intermediate layer are joined with profiled plate through layer of metallic solder. Then initiating layer is removed. Improved heat resistant target is produced; such target may undergo many cycles of temperature drops without distortion at process of ion-plasma dispersion.

EFFECT: possibility for producing heat resistant target having lowered residual porosity, increased mechanical strength and thermal stability of joining with metallic plate-substrate.
