Diamond Coatings Shine On Chevrolet Cars

摘要

The diamond-hard technology that enables razor blades to shave closer and last longer also allows the piston rings of the Ecotec 1.4L turbo engine available on the Chevrolet Sonic and Cruze to operate with less friction for better fuel efficiency and durability. This use of diamond-like carbon coating, or DLC, on a General Motors powertrain component marks a first for Chevrolet. Although the advanced synthetic surface treatment is relatively new to automobiles, it can be found on a variety of high-end products such as computer hard drives, orthopedic implants and semi-conductors. GM also is testing its use on machining tools.
