Alloys designed for high-temperature applications contain certain additions. Research has shown if those addition elements are instead applied as a superficial self-protective alloy treatment to the surface of a more basic alloy, the same high-temperature surface oxidation properties can be achieved.

Why put it IN the alloy when you can put it ON the alloy?

The active ingredients are nanoparticles in liquid suspension. The patented Minimox® process is not a coating, per se, but is more accurately described as a “surface treatment” or “surface doping.” The nanoparticles are superficially applied to stainless steels, nickel alloys, superalloys and aluminum alloys. They cause subsequent thermal oxides to have a different chemistry and structure when compared to untreated materials. The thermal oxides are significantly thinner, but more impervious. After oxidation, the treatment causes the alloy to become more “self-protective.” The composition of the ultimate protective coating is primarily a function of the alloy, not the coating material.

Minimox® Self-Protective Alloy Treatment provides well-dispersed, extremely small particles required for a superior coating with astonishing protection. After treatment, alloys heated in air exhibit a thin, adherent, dense oxide layer, rather than a thick, flaking, spalling oxide scale. The coating is applied through dipping, brushing, or spraying followed by air drying. If there is oxygen present during service, there is no other processing necessary. If there is little oxygen present during service, the surface will need to be preoxidized.
