Laser-assisted deposition of superhard carbon coatings

In the recent years, diamond and diamond-like carbon films (DLC) with nearly ideal properties have been developed for use as wear protection, low friction coatings. The hardest DLC films are called tetrahedral bonded amorphous carbon films (ta-C) and can reach a content of up to 80 % of the hardness of diamond i.e. 8,0 00 HV.
