    • The invention provides a highly durable and abrasion-resistant composite diamond-like carbon coating with controllable color which is ideally suitable as a decorative coating on electrically conductive, e.g. metal, substrates, including architectural hardware and fixtures made of brass and other metals, jewelry, medical and dental instruments, writing instruments such as pens and pencils, musical instruments, eyeglass frames, cigar and cigarette lighters, automobile hood ornaments and other components, sporting equipment and other products for leisure activities such as golf club shafts, golf club heads, cycling equipment, and fishing and hunting equipment, and other similar electrically conductive substrates. The invention also provides the process for depositing a highly adherent, highly abrasion resistant composite diamond-like carbon coating to metal substrates. The invention also provides the process for depositing a highly adherent, highly abrasion resistant composite diamond-like carbon coating to electrically conductive substrates. The composite diamond-like carbon coating structure consists of at least a first layer of Si-DLC which comprises the elements C, H, Si and possibly O and N. An additional coating containing layers of Si-DLC and DLC may be applied over top of the first Si-DLC layer. The optional additional layers of Si-DLC are also containing the elements C, H, Si and possibly O and N. The optional additional layers of DLC contain the elements C, H and possibly N. The decorative and abrasion-resistant composite diamond-like carbon coating is deposited by ion-assisted plasma deposition from carbon-containing and silicon-containing precursor gases consisting of hydrocarbon, silane, organosilane, organosilazane and organo-oxysilicon compounds, or mixtures thereof, and has the properties of Nanoindentation hardness in the range of approximately 5 to 35 GPa, modulus in the range of approximately 50 GPa to 300 GPa, thickness in the range of approximately 1 to 25 micrometers, and colors which can be varied continuously along the spectrum of: light yellow to bronze to copper-gold to burgundy to bluish-black to black, exhibiting reflected light chromaticity coordinate values (Y, x, y) values for Y of approximately 5 to 50, x of approximately 0.25 to 0.50, and for y of approximately 0.25 to 0.45. The elemental composition, refractive index and thickness of the composite diamond-like carbon coating are chosen to produce the desired reflected optical color. The deposition process parameters such as precursor gas composition, plasma power, pressure, and substrate bias voltage are adjusted to produce coatings with different elemental composition and refractive indexes, which change the reflected optical color, and hardness and elastic modulus, which effect the abrasion resistance and durability of the coating.

    • A substantially optically transparent coated substrate product with a highly adherent, abrasion-resistant diamond-like hard carbon coating is disclosed. The substrate product is comprised of a polymeric substrate, an adhesion-mediating polysiloxane polymer layer, one or more intermediate layers and an outer layer of diamond-like hard carbon. In another embodiment of the invention a thin metallic interlayer is disposed between a first interlayer layer and subsequent interlayers and/or diamond-like hard carbon. The invention also allows for the production of adherent thin film interference layer coatings (i.e. quarter wavelength stacks and anti-reflection coatings) using diamond-like hard carbon as the high refractive index layer and the interlayer(s) as the low refractive index layer or, alternatively, using diamond-like hard carbon as the low refractive index layer and the interlayer(s) as the high refractive index layer. The invention further discloses a method for fabricating the coated substrate product. The substrate product, exhibiting excellent resistance to abrasion and chemical attack, is particularly useful for commercial plastic articles such as optical lenses and sunglass lenses made of polycarbonate, CR-39.RTM., or acrylic plastics.
