  2. Chromium (II) carbide - Wikipedia

    en.wikipedia.org/wiki/Chromium(II)_carbide

    Chromium carbide is useful in the surface treatment of metal components. Chromium carbide is used to coat the surface of another metal in a technique known as thermal spraying. Cr 3 C 2 powder is mixed with solid nickel-chromium. This mixture is then heated to very high temperatures and sprayed onto the object being coated where it forms a ...

  3. Stellite - Wikipedia

    en.wikipedia.org/wiki/Stellite

    Stellite alloys are a family of completely non-magnetic and corrosion-resistant cobalt alloys of various compositions that have been optimised for different uses. Stellite alloys are suited for cutting tools, an example is Stellite 100, because this alloy is quite hard, maintains a good cutting edge at high temperature, and resists hardening and annealing.

  4. Hardfacing - Wikipedia

    en.wikipedia.org/wiki/Hardfacing

    Plasma arc welding, also called powder plasma welding; Thermal spraying; Cold polymer compounds; Laser cladding; Hardpaint; Commonly applied materials include cobalt-based alloys (such as Stellite), nickel-based alloys, chromium carbide alloys and NOREM. Hardfacing is sometimes followed by hot stamping to refinish the part or add color or ...

  5. Pyrolytic chromium carbide coating - Wikipedia

    en.wikipedia.org/wiki/Pyrolytic_chromium_carbide...

    Coating mechanical parts can help with problems of corrosion, adhering, high-temperature and mechanical wear thus reducing unplanned repairs and loss of production. The features of PCC coatings are: obtaining protective layers with high adhesion strength on parts and products made of various engineering materials including metal and non-metal ...

  6. Thermal spraying - Wikipedia

    en.wikipedia.org/wiki/Thermal_spraying

    The resulting coating has low porosity and high bond strength. [1] HVOF coatings may be as thick as 12 mm (1/2"). It is typically used to deposit wear and corrosion resistant coatings on materials, such as ceramic and metallic layers. Common powders include WC-Co, chromium carbide, MCrAlY, and alumina.

  7. Polishing (metalworking) - Wikipedia

    en.wikipedia.org/wiki/Polishing_(metalworking)

    Gray silicon carbide abrasives are used on hard and brittle substances, such as grey iron and cemented carbide, and low tensile strength metals, such as brass, aluminium, and copper. [1] Green chromium(III) oxide is the abrasive used in green compounds that are typically used to finish ferrous metals (steels).

  8. Detonation spraying - Wikipedia

    en.wikipedia.org/wiki/Detonation_spraying

    [citation needed] Many different mixtures of coating powders and D-gun settings can be used during detonation gun spraying of a material, all of which influence the final surface characteristics of the sprayed coating. Common powder materials used include but are not limited to: alumina-titania, alumina, tungsten carbide-tungsten-chromium ...

  9. Chromate conversion coating - Wikipedia

    en.wikipedia.org/wiki/Chromate_conversion_coating

    Chromate conversion coating or alodine coating is a type of conversion coating used to passivate steel, aluminium, zinc, cadmium, copper, silver, titanium, magnesium, and tin alloys. [ 1 ] : p.1265 [ 2 ] The coating serves as a corrosion inhibitor , as a primer to improve the adherence of paints and adhesives , [ 2 ] as a decorative finish, or ...
