Ceramic CoatingsApplied via High-Energy Plasma

Coating Applications

At MBI we apply ceramic coatings by utilizing advanced Plasma spray systems. Ceramic coatings are an engineering tool that can transform an ordinary metal into a high-performance surface.

Ceramic coatings are defined as non-metallic, inorganic materials. High hardness and thermal insulation are commonly recognized properties. When chosen correctly Ceramic coatings can significantly halt wear & corrosion, insulate from heat, even promise dimensional, thermal and chemical stability.

When applied by our high energy Plasma, the coatings produced are considered denser, more wear and corrosion resistant, and exhibit superior heat shield properties. Ceramic coatings are inert to acids, alkali and solvents.

Typical Properties

Bond Strength: Over 12,000 psi

  Polished 50-110 Ra (Snag-free finish)
  1-3 Ra (Ground and lapped)

Porosity: Typically less than 2%
  0% when using proper sealers

Typical Variations of Ceramic Coatings

PL-130 (Alumina-Titania)This Plasma sprayed coating is extremely popular in the textile and fiber industry. Such coatings are very hard with a fine matte finish ideal for fiber contact.
PL-106 (Chrome-Oxide)Popular for its superior corrosion and extra wear resistance. Its virtual hardness exceeds 74 Rc making it one of the hardest ceramic materials. It is widely used for seal applications on shafts, sleeves and such.
PL-201 (Zirconium-Oxide)Applied by our high energy plsam spray processes. It is known for its thermal resistance at temperatures approaching 3000 F.
PL-210 (Magnesium-Zirconate)Excellent choice for applications that require resistance to thermal shock with cyclical patterns. It is ideal to be used as coating for ingot molds and molten metal handling equipment.
PL-102 (Titanium-Oxide)This coating is considered to be extremely tough, inert with excellent resistance to hard surfaces. It is applied on shaft and high speed spindle surfaces. It works well on applications subjected to mechanical shock and impact.
