Minimox surface treatment to form self-protective alloys
Why put it IN the alloy when you can put it ON the alloy?

Stainless Steel Oxidation Resistance Improvement

The Minimox coating process was initially developed to reduce material loss due to excessive oxidation. A significant amount of data is available for a wide variety of alloys, including martensitic, ferritic, austenitic and duplex stainless steels, nickel superalloys, and aluminum alloys under a wide variety of temperatures and conditions. Please contact our office if you have questions about a specific alloy.

As an example of the versatility of this process, an assortment of alloys was partially coated with a single dip in Minimox solution and heated to 850°C for 24 hours in air. The results are illustrated in the figure below.

All of the above coupons were partially dipped in Minimox solution a single time and heated to 850°C (1560°F). Protection is afforded to all of these alloys.

One half of a stainless steel bowl was dipped in Minimox solution and heated to 927°C for 3 hours, for 3 cycles. The coated half of the bowl has a thin, adherent oxide while the uncoated half exhibits a spalling oxide.
