Coating Design

In many instances, the material which is structurally required for a component does not yield ideal surface properties for the application. Coatings can optimize these surface properties. For example, coatings can improve the wear resistance, biocompatibility, or electrical properties of a surface. A nanotechnology coating product, Minimox^™ is available to reduce oxidation and corrosion of alloyed steel at high temperatures. The coating can be applied in the field.

Self-Protection of Alloys at High Temperature

Material Interface introduces the Minimox^™ series of nanocrystalline coatings - to minimize oxidation. These nanocrystalline coatings impart significant high temperature protection to stainless steel and other alloys, including nickel-based super alloys and aluminum, by restricting oxide scale growth. With initial research funded by the U.S. Department of Energy, the nanocrystalline coating is economical and easy to apply through a simple dip, spray, or roll process. The full benefits and wide range of applications are still in the research and development stage, but please call us to discuss your applications. See www.Minimox.com for additional information.

Physical Vapor Deposition (PVD)

A wide variety of physical vapor deposition coating methods are available as well, depending upon your specifications. These coating techniques include plasma spraying, sputtering, reactive evaporation, etc. Coating materials and methods are evaluated for your application. Thin film design services are available; devices include various types of sensors and protective coatings.

Erosion Resistant Coating

Titanium-based multilayer coating for erosion resistance.

A titanium-based multilayered coating was developed to improve cavitation and particle erosion resistance of steel components. During testing, it was superior to other processes on the market. The coating was also shown to increase the fatigue life of stainless steel components. This coating is covered under patents owned by Material Interface, Inc. and is available for commercialization.

Lanthanum Hexaboride

Thin film lanthanum hexaboride can be applied through a patented coating process to reduce the work function of surfaces and provide high electron emission currents at relatively low temperatures. Thin film lanthanum hexaboride can be sputtered onto carbon nanotubes to increase the electron emission. The work function of thin film LaB₆ has been measured at 2.4 - 2.6 eV. Other applications include flat panel displays and electron optic devices.
