The article Steve mentions doesn't address existing equipment that has been in use.  I want to know how successful would it be to disassemble the wave and it's components that come in contact with the solder and have them reworked with Melonite.  I was also wondering if someone has done so, how much did it cost and was it effective.

Scott.

Hi Scott!

There was a good paper presented at last years Apex that talked about
Melonite treated stainless called "Equipment Impacts of Lead Free Wave Soldering".

The article is up on the web, just do a Google search of the title and you'll
find it... it's pretty good.

The article was recognized as the best paper presented at Apex 2003, and
explains all the tests that were done on different materials.

Melonite coating is more of a process of treating the steel than anything
else, and it does provide more protection. But if the Melonite/Nitrided steel
becomes scratched, it will degrade. The protection from Melonite is also
dependant on the type of stainless steel the parts are made from, 304 stainless is
better than 316 stainless.
Even then, inspections should be done every 6-months for the 304, and every
3-months for the 316.
