SPEC's 937 oxide/ceramic coatings are produced by the thermal spray deposition of a multi-component oxide ceramic. Utilizing Plasma Flame Spray technology, this coating is low in porosity and high in surface hardness. The anti-wetting properties of this coating make it ideally suited for applications requiring resistance to molten metals as well as resistance to surface wear. These coatings are also useful as thermal barriers.

Typical applications include Galvanizing dip tanks to resist molten zinc as well as smelt spouts and other components where resistance to molten metal splash is desired. This coating is superior to stabilized zirconia and magnesium zirconate coatings in resistance to wear.

Because of thermal expansion considerations, please contact our offices for proper coating thickness for each particular application.
