Corrosion treatments

[Kenneth66]

Have a Remington 721 that is my go to gun on just about every hunt . It has been rebarreled with a stainless barrel .
Would like to know what is the absolute best treatment you can put on a rifle for rust resistance . Is it reasonable to have everything , trigger , sear , the works , coated ?
Will any of this stuff cause problems with function ?
Would like a dull Finnish that is anti reflective , doesn't have to be camo .
If some of questions sound off track , it is because I know nothing about this process and want to know what works best and who can are some people who you would recommend for such work ? It has been pillar bedded and has a very repeatable cold shot , would not want that tampered with at all .

Thank you , interesting site .

I can offer titanium nitride and cerakote. The nitride is toughest, and the cerakote is slightly better against corrosion.

I'm also exploring treatments. I never hear about plating. Is Chrome or nickel plating ever done?

 

[riflewoman]

The problem with plating is that the internal clearances get messed up because the plating adds at least .003 thickness. So you end up with an inoperable gun.

Damn how much does tiN coating cost to do?

Parkerizing is a good and effective process but stainless won't park. It is what the military has used for years. IMO, it's the best prep for cerakote or duracoat as well. It does have its downsides. It's not real pretty or slick. The tiN sounds interesting though.

 

[riflewoman]

TiN is a vapor deposition process. They literally vaporize Titanium in a Nitrogen rich low pressure atmosphere. It is harder than woodpecker lips but I'm not sure if it reduces corrosion. It can flake off softer steels so it may not be a good application here.

I've been Parkerizing stuff on the stove top for awhile now. Got my own bead blast cab, and necessary chemicals. It leaves the dull matte finish that holds lubrication on the surface, and the surface is impregnated with zinc or manganese phosphate, which is much less susceptible to rust than blued steel. (anyone mo-expert feel free to correct me)

I believe the receiver could be done, while attached to the barrel (stainless) without affecting the barrel in the least. BUT-- I don't claim to be an expert, and you should consult one if this is done. jd

Melonite will make the stainless the same color as the carbon steel when it too is melonited. Melonite does more than just corrosion protection. Cost approximately $200.00 per gun and you do all the steel parts, shroud, cocking piece, firing pin, springs, pins, trigger guard, screws, etc.

I had 10 actions satin hard chromed in 1988, this suff it tough as all actions look exactly like the first day I got them back from Robar.

Black Chrome is another option.

Titanium nitride adds about a ten-thousandth of an inch, which has not affected a single one of the thousands of firearms we have treated. It makes the surface about twice as hard as most steels. It does help with corrosion somewhat, but will never be a paint or epoxy finish since it still has microscopic pores as any surface treatment will. Prices vary by the size of the part (small parts like screws and controls are $10-20, pistol barrels are $40, pistol slides are $80, rifle bolts and BCGs are $100-200). It can be applied to steel, stainless steel, titanium, etc. Aluminum is cutting it close with temperature. Feel free to shoot me a message if you can think of any other questions.

FWIW, I have some experience with melonited gun surfaces, and Mr. Lambeth is spot-on. Another benefit of the melonite is the super smooth surface. I have found that any concerns about galling are greatly reduced.
