Chuck, Metal spray comes in basic types, hot spray ( usually called powder spray ) requires the base material be quite hot much like brazing and the spray material will (wet) flow somewhat like brazing . The other system , cold spray requires base metal to be minimum 200 deg and not over 500 deg , work is under cut and sprayed to slightly over size and turned to finish size. It is used mostly for shaft and bearing bore repair. The hot spray will do repair on castings and manifolds , but a crack in the side of a block will have the same problem with expansion and contraction as any other type of weld . I have had both types of spray for more than 30 years and when I need to repair castings and especially manifolds I use oxy/acet cast iron rod and preheat as necessary . Below is a link to my web site with some cast iron repair and some other things , also a link from there to a sequence of the repairs . In the terra axle repair there are several pictures of the prep , spray , and the finished spray on the seal surface. george
