Abstract:
A substrate for receiving a deposit of sprayed metal droplets, said system comprising:an outer substrate on which said sprayed metal droplets are deposited, said outer substrate being movable; andan inner substrate comprising a low thermal conductivity zone having a thermal conductivity in the range of about less than or equal to 1.0 W/m.sup.2 sec., an intermediate thermal conductivity zone having a thermal conductivity in the range of about 30 to 230 W/m.sup.2 sec., and a high thermal conductivity zone having a thermal conductivity in the range of about greater than or equal to 400 W/m.sup.2 sec, wherein said low thermal conductivity zone is disposed adjacent said outer substrate where a leading edge of said sprayed metal droplets are deposited on said outer substrate, said high thermal conductivity zone is disposed adjacent said outer substrate where a bulk layer of said sprayed metal droplets have accumulated on said outer substrate, and said intermediate thermal conductivity zone is disposed between said low thermal conductivity zone and said high thermal conductivity zone.
