This seemed to be in reference to a co-deposition of a metal and a polymer, but I can't see what that has to do with a eutectoid reaction. To me a eutectoid reaction is one solid solution going to two upon cooling through a set temperature (like a martensitic transformation in steel). Sorry, my metallurgical roots are showing. Perhaps some kind person out there can enlighten me. Janet Rice ---- HELLO, Eutectoid plating may refer to a codeposition process. I have an old piece of equipment here.,that utilizes an oxy-acetylene torch system . it was produced by "eutectic corp" it is a spray unit that codeposits a polymer/metal powder onto metal. it has been reffered to as a kind of "plate",though not in the std sense of the term. this is normally used for repair/build-up of a base metal,but also has applications for hardness/abrasion resistance. Ron Landrette plating equipment supplier - Bristol, Connecticut ---- This term probably has more than 1 meaning, however it may refer to codeposition of an alloy at it's eutectic concentration. As an example solder plate in the electronics field is usually 63% tin and 37% lead. If you looked at a Sn-Pb phase diagram you would find that is the alloy that gives the lowest melting point or eutectic point. Paul D. Stransky, CEF - Putnam, Connecticut
