- FIG. 1 is a schematic diagram of a vapor deposition apparatus (e.g.,
- Figs. 2-3 are cross sectional view of portions of coated trim products according to different embodiments of this invention
- Fig. 4 is a flowchart .illustrating certain steps taken in making trim product(s) according to certain example embodiments of this invention.
- Automotive trim product(s) e.g., bodyside molding, applique, door handle, wheel cover, fender, bumper, fascia, grill, bumper edging, etc.
- are coated with the Cr inclusive layer(s) in vapor deposition chamber 1 are coated with the Cr inclusive layer(s) in vapor deposition chamber 1, and may be coated in the following manner according to one example embodiment of this invention.
- a PECVD type coating apparatus is described herein and shown in the drawings, other types of deposition may instead be used (e.g., other types of plasma CVD, physical vapor deposition, cathodic arc vapor deposition - electric arc, etc.).
- a coil (not shown) may be provided inside or outside of the chamber 1 in order to create an electric field that may help direct ions from a plasma toward substrate(s) to be coated.
- a substrate 2 e.g., plastic substrate comprising a polymer such as ABS, polycarbonate, polyethylene, polypropylene, olefm, and/or the like
- substrate 2 is of or includes ABS (acrylonitrile butadiene styrene)
- ABS acrylonitrile butadiene styrene
- the ABS may include butadiene molecules intermixed in a styrene-acrylonitrile copolymer matrix.
- substrate 2 is preferably polymer based in certain embodiments of this invention, it may be of other materials (e.g., glass or metal) in alternative embodiments of this invention.
- substrate 2 may be coated with one or more conductive layers 4 and/or 4' in certain embodiments of this invention.
- conductive layer(s) 4 and/or 4' may be of a conductive material such as a metal or metal alloy.
- layer 4 may be of or include Ni, Cr, NiCr. Al or the like in certain example embodiments of this invention.
- Optional additional layer 4' may be of similar material(s) (e.g., Ni, Cr, NiCr, Al, etc.).
- Conductive layers 4 and/or 4' may be formed on substrate 2 by dipping the substrate into abath(s) including the metal(s) in certain example embodiments of this invention (see step B in Fig. 4).
- the substrate 2 may be shaped (e.g., via injection molding, extrusion, vacuum-forming, or the like) into the desired vehicle trim shape either prior to or after coating with layer(s) 4 and/or 4'.
- At least one substrate 2 is then positioned in vapor deposition chamber 1 (see final vehicle trim products 5 - after coating - in chamber 1 in Fig. 1).
- the substrate(s) 2 may be supported ' by (e.g., hung from or otherwise supported by) a conductive support 3 located in the chamber 1.
- Support 3 may take the form or a rack, a bar(s), or any other suitable supporting structure in different embodiments of this invention.
- a biasing signal V from power source 7 is applied to the f substrate(s) 2 in chamber 1, e.g.. via conductive support 3 or in any other suitable manner.
- Biasing signal V may be in the form of a square wave, sine wave, or any other suitable biasing signal in different embodiments of this invention. All coated substrates 2 in the
- chamber 1 may be electrically biased at the same time in the same manner in certain embodiments of this invention, while in other embodiments of this invention different coated substrates 2 in chamber 1 may be biased at different times so as to allow some coated substrates 2 to be coated during a first period of time and other coated substrates 2 to be coated during another period of time.
- Cr inclusive gas is introduced into vapor deposition chamber 1 in the following manner in certain example embodiments of this invention.
- a Cr inclusive material such as Cr(CO) 6 (chromium hexacarbonyl) is provided in inner container 8. Since Cr(CO) 6 is a liquid at room temperature, it may be at least partially in liquid form at the bottom of inner container 8.
- Temperature controller 9 controls the temperature of a heating liquid (e.g., water) 10 provided in outer container 11 so as to surround at least a portion of inner container 8. When controller 9 heats liquid 10, it in turn causes the liquid Cr(CO) 6 to be heated (e.g., to about 70-100 degrees C) thereby leading to vaporization of the same in inner container 8.
- a heating liquid e.g., water
- At least one carrier gas (e.g., Ar, N 2 and/or a hydrocarbon such as C 2 H 2 ) from source 12 may flow into container 11.
- Flow controller 14 is capable of controlling the flow rate of the gas(es) into the chamber 1.
- gas including Cr, N, C, H, and/or Ar flows into vapor deposition chamber 1 at inlet 15.
- another gas source 20 may be provided in order to enable another gas (e.g., NH 3 , or any other suitable gas(es)) to be introduced into chamber 1 via flow controller 21 and inlet 22.
- a heater (not shown) may be provided in or around chamber 1 in order to heat the interior of the same.
- the coated substrate(s) 2 is/are electrically biased (e.g., negative biasing with DC), a glow discharge is generated (e.g., between the biased substrates and the wall of chamber 1). A plasma is thereby generated in the chamber, due to the presence of the gas and the biased coated substrate(s).
- the plasma includes ions such as Cr " , " , 0 ⁇ and/or C ⁇ . Other ions may also be present in certain embodiments. While in chamber 1, the coated substrate(s) may or may not be heated in different embodiments of this invention.
- the electrical biasing of the coated substrate(s) 2 causes ions (e.g., Cr , N , O ' and/or C ⁇ ions) to be drawn toward and onto the coated substrate(s) 2 so as to coat the same with Cr inclusive layer 16 (see step C in Fig. 4).
- Cr inclusive layer 16 is formed on substrate 2 over conductive layer(s) 4 and/or 4' so as to form the vehicle trim product 5 (see Figs. 2-3).
- the chamber 1 may in some example instances be evacuated before and/or while the plasma is struck in certain embodiments of this invention.
- step D in Fig. 4 they may or may not be further processed (e.g., polished, shaped, etc.), and may then be attached to a vehicle in a known manner (see step D in Fig. 4).
- the plasma in vapor deposition chamber 1 may include ions such as Cr + , N ⁇ , 0 ⁇ and/or C ⁇ ions.
- the resulting vapor deposited layer 16 formed in chamber 1 includes Cr. Additionally, the layer may also include one or more of N, O and C.
- vapor deposited layer 16 may comprise chromium nitride, chromium carbide, chromium oxide, chromium oxynitride, chromium oxycarbide, and/or chromium carbide nitride in certain example embodiments of this invention.
- layer 16 includes from about 20-100% Cr (more preferably from about 20-90% Cr, even more preferably from about 25-80% Cr, and still more preferably from about 30-70% Cr), from about 0-75% C (more preferably from about 5-60% C, even more preferably from about 5-30% C), from about 0-40% O (even more preferably from about 1-40% O, and most preferably from about 5-20% O), and from about 0-40% N (more preferably from about 1-35% N, even more preferably from about 4-30% N).
- Other elements/materials such as H (e.g., from 0-25%,. possibly from 1-20%) may also- be included in layer 16 in certain embodiments of this invention.
- the percentages above are atomic %.
- layer 16 provides a chrome-like or dark-chrome like coloration/appearance to the trim product.
- the visual appearance comprises a shiny metallic-looking finish that is not ⁇ uite bright silver but instead is more of a charcoal-like color.
- the color of the trim product is on the charcoal side of conventional bright metallic chrome.
- the dark- chrome may have significant reflection to an extent so that for example a person could see himself/herself via a reflection therefrom in ambient atmospheric conditions. This is advantageous in certain instances, as it is difficult to otherwise obtain such coloration/appearance in an efficient and cost-effective manner.
- the substrate 2 may be Ni plated in chamber 1 instead of Cr plated, in the manner discussed above using Ni inclusive gas.
- the Cr(CO) 6 liquid to be vaporized is provided for purposes of example, and is not intended to be limiting unless specifically claimed.
- layer 16 may be provided at a thickness of from about 0.5 to 50 ⁇ m. more preferably from about 1 to 25 ⁇ m.
