Microplasmic Corporation, an Research & Development company developed a unique U.S. patented surface coating technology for all types of aluminum, magnesium, titanium alloys as well as some reactive metals. As a result, light and inexpensive aluminum, magnesium or titanium coated with this process can replace heavier steel or more expensive composite materials required by many manufacturing industries. This process creates a thick ceramic coating, resistant to wear, electricity, chemical corrosion, and heat. The desired coating thickness is achieved with speedy production, economy, and produces no hazardous waste. Experimental findings on anodization/cathodization are present issues involved in scaling up the process for industrial applications. You can find more information about this process on the company's website.
