Glock Ges.m.b.H., an Austrian firearms manufacturer, uses a black Parkerizing process as a topcoat to a Tenifer process to protect the slides of the pistols they manufacture. After applying the Tenifer process, a black Parkerized finish is applied and the slide is protected even if the Parkerized finish were to wear off.
Field immersion comparison chart ASTM B117 Salt Spray Test The chart on the right shows a comparison of corrosion resistance against other surface treatments, based on field immersion tests. Test conditions for the immersion test are full immersion in 3% sodium chloride plus 3 g / L of hydrogen peroxide for 24 hours.

The final matte, non-glare finish meets or exceeds stainless steel specifications, is 85% more corrosion resistant than a hard chrome finish, and is 99.9% salt-water corrosion resistant. [34] After the Tenifer process, a black Parkerized finish is applied and the slide is protected even if the finish were to wear off.
This coating produces a similar color to the one the oxide conversion does, but tends to rub off easily and offers less abrasion resistance. The application of oil, wax, or lacquer brings the corrosion resistance up to par with the hot and mid-temperature. Applications for cold black oxide process include tooling and architectural finishing on ...
If properly performed, the results do not harm or change the finish of the protected surface. Application of gentle heat sufficient to melt the waxy hydrocarbons allows cosmoline to drip off. Penetrating oil (such as WD-40 or CRC 5-56 CLP) sprayed and allowed to soak in until cosmoline is restored to a viscous-fluid state allows it to be wiped off.
The salt spray test (or salt fog test) is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings.Usually, the materials to be tested are metallic (although stone, ceramics, and polymers may also be tested) and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal.
Innovations are taking place in paint industry as well. These days, automotive paints come in liquid form, spray form, and powder forms:- Liquid: Usually polyurethane paints. Compressor is needed to apply. Spray: This is as same as perfume in spray bottle. Made for DIYer. Powder or additive: Paints in powder form applied after mixing in paint ...
