There is an aluminum hardcoat surface treatment called Akadizing from Lovatt Processes that would resolve many issues I've seen mentioned in various posts. An aluminum part has successfully replaced a steel drive shaft seal assembly for an Indy car by outperforming the steel unit in crash testing. It also has incredible hardness (9.2 - 9.7 on the Mohs scale) and corrosion resistance. They offer to do test parts for interested parties so testing can be done to verify the benefits and have many test reports available.
Yes, I'm affiliated with the company and am trying to spread the word on this incredible metal treatment that has been available for 40 years, but not heavily marketed. Akadized parts are on the space shuttles, stealth aircraft, motorcycle clutches,and numerous other challenging applications. Their web site is www.lovattprocesses.com.
Ann, thanks for the clarification. So far I didnít think in that angle, so what I understood is as an effort to minimize the engine load, companies are planning to replace the heavy weight metallic parts with mild weight materials and in continuation to that effort they are using Aluminum wheels instead of steel, am I right.
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
Alcoa has unveiled a new manufacturing and materials technology for making aluminum sheet, aimed especially at automotive, industrial, and packaging applications. If all its claims are true, this is a major breakthrough, and may convince more automotive engineers to use aluminum.
NASA has just installed a giant robot to help in its research on composite aerospace materials, like those used for the Orion spacecraft. The agency wants to shave the time it takes to get composites through design, test, and manufacturing stages.
The European Space Agency (ESA) is working with architects Foster + Partners to test the possibility of using lunar regolith, or moon rocks, and 3D printing to make structures for use on the moon. A new video shows some cool animations of a hypothetical lunar mission that carries out this vision.
