Transcript of SCRATCH RESISTANT
by: Josh Cianciotto
Question one: How was this product originally used in space?
This product was origanally used in the space program by NASA's Dr. Ted Wydeven of the Ames Research center. He first used the scratch resistant plastic lens while working on a spacecraft water purification system. The research continued as NASA developed an abrasion-resistant coating for the astronaut space helmet visors and other plastic surfaces of aerospace equipment.
Question two: How is this product used on earth?
Scratch resistant lenses are used on earth for sunglasses, glasses and safety glasses. With normal wear they last ten times longer than the most widely used plastic optical lenses.
Question three: Did the design form or function change when it was adapted to earth?
Yes it got changed for the better. Lewis Research Center tried to get the advantages of diamond without the cost penalty by depositing a thin film of Diamond-Like Carbon (DLC) on an inexpensive substrate or supporting material. An Air Products spinoff company-Diamonex-used the NASA technology along with its own proprietary technology in developing both polycrystalline diamond and DLC coatings for commercial optical products. Sunglasses with this coating are scratch resistant and shed water more easliy, thus reducing spoting.
Question four: Was the product originally proposed for a mission?
No, but it is used for the visor on the space helmet that astronauts use on missions when they spacewalk.
Question five: What other information do you have about this space spinoff?
Today additional uses for DLC coating include plastics processing, the semiconductor industry, the racing and automotive industry, and engineering applications like wind energy technology, aviation technology, and medical technology.
