Does it wear like blued finish ??
Does it rust ??
You can find a great deal of technical info by googling Melonite QPQ. There are several US companies offering this process.
The black finish that is put on top of the melonite scratches easier than the black carbon finish that Glock uses, though.
Two persistent and incorrect rumors.
1. Tenifer/ Melonite cannot be done in the US because of the EPA.
False: The original process used cyanide salts, the current one does not. Both have been available in the US for quite some time.
2. Tenifer, Melonite and Tufftride are different processes.
False: They are different trade names for the same process. Tenifer is used in Europe, Melonite in the US, and Tufftride everywhere else.
I don't know of any companies set up to do individual firearms, but a few have had them done at Burlington, in SoCal. This process is cheaper than hard chrome but requires a big investmnet in hardware and has much higher startup costs.

It's a surface nitride process, about 70 Rc hardness IIRC. Metal Treaters in Minneapolis/St. Paul was our vendor. http://metaltreaters.com/page3.html
For example, carbon steel would receive the QPQ version, while QP is more appropriate for stainless steel.
Here's a link to a company's site in CA who offers this process ... http://burlingtoneng.com/capabilities.html
It's an interesting subject, and one in which a lot of urban legends abound.
Well my main Q is: I like want to get a Walther p99 but I want to know if the Melonite finish will wear off like the blue on other pistols ??
I like the SS look, but I think its time for an all black pistol.
My SW99 stainless steel slides, which have received the Melonite QP treatment, have proven to be very durable as far as holster wear/scratch resistance is concerned.
Ordinary bluing is generally considered to be right down there at the bottom of the scale, or right close to it, when it comes to "wear resistance" and corrosion resistance issues.
There are a lot of different proprietary finishes being offered nowadays, too, and some may offer better wear & corrosion resistance than some others. Buyer beware ...
Some folks who carry 'blued' finish SIGARMS in another agency have reportedly complained that some of them would start to oxidize by the end of their 8-hour Patrol shifts in certain weather conditions.
I remember a lot of our senior guys carrying issued blued Colt Pythons when I was new, and watching some of them methodically wipe down their revolvers at the end of each shift, and take special care if they had been exposed to rain/moisture. Of course, a lot of those older leather holsters covered more of the revolvers than many of the duty holsters used with some pistols nowadays, and maybe that had something to do with the revolvers being somewhat less exposed to the elements over short periods. Dunno ...
I think nitrocarburizing treatments offer some distinct advantages over some other 'finishes', but I also think they still require some reasonable owner/user care and maintenance for optimal service life.
Just my thoughts ...
RUBZERK, The Melonite can wear with use, altough it is much tougher than bluing in this regard and even if the black wears off you are still left with a highly corrosion resistant steel. It is one of the best finishes out there and I think one of the toughest. I think we will see more makers using it in the future, especially with stainless steel prices headed up.
