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. |
