Abstract

Method to obtain coatings on mechanical parts by P/M techniques be means of a paste composed by a binder and metal and/or ceramic powders comprising operations of slowly adding to the paste an additive formed by a solution of free or complex ions preferentially metallic ones in a polar solvent; homogenizing the paste mixture and the additive; applying of the product obtained that way on the surface of a substrate to coat; removing the binder by a first stage of slow heating (a) and a second stage of fast temperature (b) increase. The mentioned additive is chosen among those that do not produce precipitates under atmospheric pressure below 80o C; they precipitate between 80 and 120o C; and their precipitates are stable below 200o C.
