Appl. No.:

12/155762

Inventors:

David D. McLean - Hazel Park MI, US

Assignee:

Guardian Industries Corp. - Auburn Hills MI

International Classification:

C23C 16/00
C23C 16/455
C23C 16/453

US Classification:

118715

Abstract:

Certain example embodiments relate to a burner for use in combustion deposition depositing a coating on a substrate. First and second spaced-apart combustion gas manifolds are configured to respectively produce first and second flames (which may effectively combine to form a single flame front beyond the outer face of the burner in certain example embodiments). The first and second combustion gas manifolds form a precursor reaction zone therebetween. An adjustable precursor delivery manifold located between the first and second combustion gas manifolds is configured to receive a precursor used in forming the coating. The precursor delivery manifold is positioned so as to substantially directly provide the precursor to a desired or predetermined portion of the precursor reaction zone. The precursor delivery manifold includes first and second cooled walls arranged to reduce the occurrence of precursor pre-reactions upstream of the precursor reaction zone. The burners of certain example embodiments may be used to combustion deposition deposit metal oxide coatings onto glass substrates.

Abstract:

Certain example embodiments of this invention relate to a method of forming a coating on a glass substrate using combustion deposition. A glass substrate having at least one surface to be coated is provided. A reagent is selected. A precursor to be combusted with the reagent is introduced. Using at least one infrared burner, at least a portion of the reagent and the precursor are combusted to form a combusted material, with the combusted material including non-vaporized material. The glass substrate is provided in an area so that the glass substrate is heated sufficiently to allow the combusted material to form the coating, directly or indirectly, on the glass substrate. The coating may be substantially uniform. In certain example embodiments, a silicon oxide coating may be deposited, which increases visible transmission of the glass substrate by at least about 1. 7%.

International Classification:

US Classification:

Abstract:

Certain example embodiments relate to a burner for use in combustion deposition depositing a coating on a substrate. An infrared (IR) burner generates radiant energy in an area between the burner and the substrate. A delivery device (1) provides a stream comprising a substantially vaporized precursor and a carrier gas from a location remote from the radiant energy generated by the IR burner, and (2) causes the stream to flow between the substrate and the IR burner. The stream is substantially laminar when exiting the delivery device. The radiant energy is sufficient to cause the precursor in the stream to be combusted and to heat the substrate to allow at least a portion of the combusted precursor to form the coating, directly or indirectly, on the substrate. The burners of certain example embodiments may be used, for example, to combustion deposition deposit metal oxide coatings onto glass substrates.

International Classification:

B05D 1/38
B32B 17/06

US Classification:

428331, 427201, 428428

Abstract:

Certain example embodiments relate to the deposition of metal oxide coatings via combustion deposition. In certain example embodiments, the metal oxide coating may be a silicon oxide coating (e.g., SiO, or other suitable stoichiometry) and, in certain example embodiments, the silicon oxide coating may serve as an anti-reflective (AR) coating. In certain example embodiments, a percent visible transmission gain of at least about 2.0%, and more preferably between about 3.0-3.25%, may be realized through the growth of films on a first surface of the substrate. The coatings produced in accordance with certain example embodiments possess an enhanced transmission increase over previously combustion deposition produced single-layer anti-reflective coatings. This may be accomplished in certain example embodiments by provided mixed or graded microstructure metal oxide coatings (e.g., silicon oxide growths that alternate between using process conditions that produce small nucleation particle size distributions and process conditions that produce large agglomerate nano-particle size distributions) and/or by in situ nano-particle matrix loading of metal oxide coatings via combustion deposition.

US Classification:

428432, 42725532

Abstract:

Certain example embodiments relate to the combustion deposition depositing of coatings comprising metal oxide matrices loaded with hollow metal oxide particles. The hollow metal oxide particles may be produced by combusting an emulsion including an aqueous phase and an oil phase, and an optional surfactant. The aqueous and/or oil phase may include a first metal oxide precursor. A second metal oxide precursor may be combusted in addition to the emulsion to produce a dense binder layer, acting as a “glue” to hold the hollow particles together. The matrix and the hollow particles comprising the coating may be of or include the same metal or a different metal. In certain example embodiments, the microstructure of the final deposited coating may resemble the microstructure of coatings produced by wet chemical (e.g., sol gel) techniques.

Abstract:

Certain example embodiments relate to an in-line scalable system that may be used in the combustion deposition depositing of thin films.

In certain example implementations, multiple burners and multiple cooling sections are provided to a single module in alternating order. The systems of certain example embodiments may, in addition or in the alternative, comprise a combined flame guard and exhaust system. The combined flame guard and exhaust system of certain example embodiments advantageously may provide a means to reduce the amount of interference of the deposition process by ambient conditions, improve flame uniformity in the deposition zone, contain and exhaust combustion products while reducing restrictions to the stable operating space of the combustion deposition process, etc.

US Classification:

2041921, 2191216

Abstract:

Certain example embodiments relate to systems and/or methods for preferentially and selectively heat treating conductive coatings such as ITO using specifically tuned near infrared-short wave infrared (NIR-SWIR) radiation. In certain example embodiments, the coating is preferentially heated, thereby improving its properties while at the underlying substrate is kept at low temperatures. Such techniques are advantageous for applications on glass and/or other substrates, e.g., where elevated substrate temperatures can lead to stress changes that adversely effect downstream processing (such as, for example, cutting, grinding, etc.) and may sometimes even result in substrate breakage or deformation. Selective heating of the coating may in certain example embodiments be obtained by using IR emitters with peak outputs over spectral wavelengths where the conductive coating (or the conductive layer(s) in the conductive coating) is significantly absorbing but where the substrate has reduced or minimal absorption.
