My project of Parkerizing a Walther PPK/S

Parkerizing or Phosphating is a Metal Finish that really gained popularity when the US Government was looking to replace the typical blued finish on most small arms with a Rust Resistant and Anti Reflective Finish that would be both Durable and Abrasion Resistant and hold up in all weather extremes, for this they chose Parkerizing or Phosphating.

The Parkerizing technique is a Phosphate etching process that produces a Hard Matte or Dull finish that is both very Durable and Anti Reflective and with excellent oil holding properties.

The most commonly types used are the Grey Oxide and Black Manganese.  Both are in use by many Military and Civilian Manufacturers in many countries on a wide variety of products.

The standard Grey Oxide Parkerizing may range from light grey to a darker grey depending on the type and hardness of the metal it is being applied to, whereas the Black Manganese Parkerizing will usually always be in the Charcoal Black category.

Either type of Parkerizing Finishes will offer much more protection from harsh weather than bluing, and is very simple to apply and maintain.

Parkerizing is much easier to use than bluing because it is a Matte Finish so the parts or items you want to Parkerize do not have to be polished, they can be acid dipped, sanded, bead blasted or sand blasted. In fact a lot of nicks and scratches that would show up on a blued item would not even be seen after Parkerizing.

Parkerizing is an immersion process requiring the solution to be heated to approximately 190 + degrees and the dipping time can range from 5-45 Minutes or so, depending on the hardness of the metal and the desired Finish.

Actually the only equipment required is a Stainless Steel Tank or Pot and a Heat source and a Thermometer.

 
 
My poor rusty Walther PPK that has been neglected. (not by me)                   Fresh out of the bead blaster and ready to de-grease.

 
My parkerization set up. It has to be done at around 190 degrees.                 Small parts parkerizing.

 
Small parts scrubbed and ready for degreaser.                                            Soaking parts in the degreasing wash.

 
The entire PPK, parkerized and ready for the water displacement bath.          The PPK after its first oil wash.

 
Re-assembled and oiled. Beautifully parkerized, super-durable finish.             James Bond would be proud to carry this Walther PPK!
