<p>Process for manufacturing a finished product consisting, at least partially, of an alloy based on copper, nickel and tin which has undergone spinodal decomposition characterised in that: … … a) a liquid bath of the alloy based on Cu Ni Sn is prepared, also containing titanium and, optionally, lead … b) a semifinished product is formed by spray (sputtering) deposition of this alloy on a substrate with, where necessary, "flash" annealing followed by rapid quenching … c) the product obtained after transformation of the semifinished product is subjected to a thermal tempering treatment so as to achieve spinodal decomposition of that part of the said product consisting of alloy based on Cu Ni Sn, and so as thus to obtain a finished product. … …<??>Semifinished product or product obtained according to this process. …<??>Application to the manufacture of machinable products and connectors based on Cu Ni Sn of high and homogeneous hardness.</p> |
