  3. Surface treatment of metals, Get a quote, Tantec

    Surface Treatment of metals. Metal surfaces can be treated by using special insulated electrodes or the PlasmaTEC-X treatment nozzles. Treatment of Metal surfaces is often a matter of both cleaning and surface activation. Often Stainless steel surfaces are treated with either Ceramic Corona Electrodes or PlasmaTEC nozzles to ensure max.

    Steel Conversion Coatings (Black Oxide & Phosphate) (Contrasted to an applied coating which bonds to the metal but does not react chemically.) A black oxide conversion coating is applied to ferrous alloys when oxidizing salts react with the iron to form magnetite (Fe 3 O 4 ), the black oxide of iron.

  5. Black Finish for Stainless Steel

    Black Finish for Stainless Steel. A discussion started in 2001 but continuing through 2019. 2001. RFQ: I produce a product that uses 1/2 stainless steel tube which I think looks great, but my customers want it finished black. Powder coating isn't hard enough to meet my needs.

  6. Black oxide - Wikipedia

    Copper. Black oxide for copper, sometimes known by the trade name Ebonol C, converts the copper surface to cupric oxide. For the process to work the surface has to have at least 65% copper; for copper surfaces that have less than 90% copper it must first be pretreated with an activating treatment.

  7. What Is Black Carbon Steel? (with pictures)

    Oct 27, 2019 · Pure iron can be melted and shaped, but tends to be soft. Adding carbon will strengthen the metal, and most carbon steels contain one to two percent carbon. Black carbon steel is created during the manufacturing process when high temperatures create a thin layer of oxidized iron on the outer surface.

  8. Phosphate conversion coating - Wikipedia

    Phosphate conversion coating. Iron phosphates are typically used as a base for further coatings or painting and are applied by immersion or by spraying. Zinc phosphates are used for corrosion resistance (phosphate and oil), a lubricant base layer, and as a paint/coating base and can also be applied by immersion or spraying.

    Black oxide is a coloring of the base metal, no metal is removed or deposited. Dark black color: (No patina or rainbow effect) The surface of the part may be shiny or matte depending on the surface of the part and the after finish applied. For example, a polished surface will retain its luster after black

  13. Conversion Coatings - Black Oxide, Phosphate, Chromate ...

    Steel Conversion Coatings (Black Oxide & Phosphate) Black Oxide: Black Oxide is a conversion coating formed by a chemical reaction with the iron in the metal to form an integral protective surface. (Contrasted to an applied coating which bonds to the metal but does not react chemically.)

  14. What is Passivation? How Does Stainless Passivation Work?

    Per common passivation specifications ASTM A380 & A967, passivation is the removal of exogenous iron or iron compounds from the surface of stainless steel by means of a chemical dissolution, most typically by a treatment with an acid solution that will remove the surface contamination, but will not significantly affect the stainless steel black surface treatment pipe steels
