Yesterday I posted about a P3-AT restoration I did and used this plating solution. http://www.ktog.org/cgi-bin/yabb2/YaBB.pl?num=1200253566
I wish I could take credit for finding it, but it was specified by a customer for some custom parts we made. I had a few emails asking about it so I did some research today. The patent holder and sole distributor of the plating solution is in Germany, but they were kind enough to give me phone numbers of 3 plating shops that use it for guns. I was able to talk to 2 of them and they had nothing but great things to say about it. They both do plating for high end custom gun makers and competitive shooters.
The manufacture describes it as extremely hard and slick, abrasion resistant, low-friction, high lubricity coating that has the whiteness of Hard Chrome and the characteristics of diamond and graphite.
Hardness: 4140 gun steel blued 48 HRC - Nickel 45 HRC - Hard Chrome 65 HRC - Cobalt Boron Nitride 71 HRC
Friction Co-Efficient: 4140 gun steel blued .19 - Nickel .13 - Hard Chrome .1 - Cobalt Boron Nitride .04
Both shops plates the inside of the barrel and had similar chrono tests of a 4%-8% gain in velocity compared to a similar non plated barrel.
Now I can see why the P3-AT I plated is so smooth. The next step is to plate a slide and barrel.
