Parkerizing - Future

Future

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. Used this way, Parkerizing is thus becoming a protective and decorative finishing technique that is used over other underlying improved techniques of metal protection.

Traditional iron phosphate, zinc phosphate, and manganese phosphate electrochemical conversion coatings, including Parkerizing variations, have all been criticized in recent years for introducing phosphates into surface water systems, encouraging the rapid growth of algae (eutrophication). As a result, in recent years, new, emerging technology alternatives to traditional phosphate coatings have started to see limited use, for replacing all phosphating coatings, including Parkerizing. The majority of these newer conversion coatings are fluorozirconium-based. The most popular of these fluorozirconium-based conversion coatings, introduced in 2005, incorporates the transition metal vanadium. This new, more environmentally-friendly coating is referred to as a vanadate conversion coating. Besides vanadate coatings, arsenate coatings may theoretically provide similar protection, at the risk of being a health hazard to humans and animals. It remains to be seen if these, or other new electrochemical conversion coatings, will ultimately replace traditional phosphating and Parkerizing.

Various if similar recipes for stovetop kitchen Parkerizing circulate in gun publications at times, and Parkerizing kits are sold by major gun-parts distributors such as Brownell's.

Famous quotes containing the word future:

    The future is just as much a condition of the present as is the past. “What shall be and must be is the ground of that which is.”
    Friedrich Nietzsche (1844–1900)

    In no nation are the institutions of progress more advanced. In no nation are the fruits of accomplishment more secure. In no nation is the government more worthy of respect. No country is more loved by its people. I have an abiding faith in their capacity, integrity and high purpose. I have no fears for the future of our country. It is bright with hope.
    Herbert Hoover (1874–1964)

    The moments of the past do not remain still; they retain in our memory the motion which drew them towards the future, towards a future which has itself become the past, and draw us on in their train.
    Marcel Proust (1871–1922)
