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.

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

A wide variety of physical vapor deposition coating methods are available as well, depending upon your specifications. These 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

Client Solutions

Minimox^TM nanocrystallline coating was used as a pre-treatment before heat treating stainless steel components, eliminating the need for post-heat treat sandblasting.
Selection of the optimum method of applying titanium nitride coating increased the life of cutting tools.
Thin film temperature sensors were manufactured with sputtered platinum coatings.

Minimox^TM Nanotechnology Coatings

The micrograph shows the high degree of spalling on the unprotected stainless steel surface heated to 1000°C. The surface treated with the Minimox^TM nanocrystalline coating exhibits essentially no flaking. The Minimox coating process has been developed to provide the extremely small, well-dispersed particles necessary to provide this astonishing protection at an affordable price. For additional details, please visit the nanotechnology coating information sheet and press release.

Erosion Resistant Coating

A titanium-based multilayered coating was developed to improve cavitation and particle erosion resistance of steelcomponents. 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 lathanum 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. Applications include flat panel displays and electron optic devices.

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.
