Definitions
- the present invention relates to coated metal components and, more particularly, substantially chromium-free metal components with a substantially chromium-free protective coating containing silicon, and methods of forming such substantially chromium-free protective coatings on substantially chromium-free metal components.
- Inorganic layers and coatings are often formed on a surface of a substantially chromium-free metal component to protect and mask the underlying metal substrate and to extend its useful life, such as by providing corrosion resistance and chemical resistance.
- zinc may be applied as an inorganic protective coating on iron or steel substrates either electrochemically by plating or by hot dip methods, such zinc protective coatings may be subject to corrosion in the form of a white rust defect.
- a conversion coating such as a chromate may be applied as a pretreatment on the iron or steel substrate before the zinc is applied.
- the process forming chromate coatings presents environmental and health risks that reduce their prevalence of use and that have instigated research to identify suitable substitute environmentally friendly coatings to replace chromate coatings.
- Hard chrome plating is another common inorganic protective coating used in industrial equipment to reduce friction and wear.
- Hard chrome coatings are applied by electrolytic deposition processes.
- electrolytic deposition processes involve chemicals that are extremely hazardous, toxic, corrosive, and damaging to the environment.
- the use, storage, and disposal of the chemicals involved in electrolytic deposition processes are governed by law in most jurisdictions. Personal safety equipment and proper containment facilities are considered mandatory.
- Copper is most frequently used as a pure, unalloyed metal.
- copper tubing and pipes are used to transport potable water in a residence.
- copper corrodes over time and, if sulfur has been present, turns blue due to the formation of copper sulfate from sulfur exposure.
- Organic (i.e., carbon-based) coatings such as conventional paints, may also be used to protect substantially chromium-free metal substrates.
- organic coatings may deteriorate at high temperatures because of the presence of a polymer operating as a binder to confer film-forming properties. Consequently, organic coatings may lose their protective ability such that the formerly protected metal substrate is vulnerable to corrosion or chemical attack.
- GB 893 397 A relates to a process for coating metals to render them corrosion resistant.
- a method is disclosed that comprises coating the metal with an aqueous solution of one or more mono-organosilanes or a water-soluble partial hydroylsate of such a silane or silanes and curing the coating at a temperature of at least 100 °C.
- WO 98/30735 A discloses a method of preventing corrosion of metals using silanes.
- the method comprises applying a first treatment solution directly onto the surface of the metal, wherein the first treatment solution contains at least one multi-functional silane having at least two trisubstituted silyl groups, and wherein the substituents are individually chosen from the group consisting of alkoxy and acetoxy.
- the present invention is defined in claim 1.
- Preferred embodiments are defined in claims 2 to 5.
- the protective coating may be, for example, effective for reducing corrosion and sulfidation of the underlying metal of the metal comopnent.
- the metal component may be formed from any metal including, but not limited to, iron, aluminum, titanium, copper, nickel, and alloys of each of these metals such as mild steel and stainless steels.
- the properties of the protective coating may be tailored according to the type of atmosphere in which the substantially chromium-free, silicon-containing fluid composition layer is heated.
- the fluid composition layer may be heated in argon to form, for example, a metal silicide protective coating.
- the substantially chromium-free, silicon-containing protective coating of the present invention would operate to mask and protect the underlying base metal of the metal component at room temperature and may retain the protective properties at elevated temperatures that area significantly above room temperature.
- the heat resistance would be advantageous in comparison to, for example, conventional organic or carbon-based paints that deteriorate at high temperatures and, therefore, lose their protective ability.
- the protective coating of the present invention would also eliminate the risks and concerns associated with producing conventional chromate coatings and hard chromium plating, among other types of conventional coatings.
- the protective coating of the present invention may also be applied to metal components that otherwise would not receive such coatings, such as copper tubing.
- the protective coating of the present invention may also reduce the need to alloy the metal of a component with another metal to impart corrosion resistance.
- a method for forming a substantially chromium-free protective coating on a substantially chromium-free metal component that applies a substantially chromium-free fluid composition layer containing silicon is applied to the metal component and heats the composition layer in a non-oxidizing atmosphere to a temperature exceeding 204 °C (400 °F) that is sufficient to convert the composition layer to the substantially chromium-free protective coating.
- a substantially chromium-free, silicon-containing layer 12 is applied to at least a portion of an original surface 14 of a substantially chromium-free metal component 10.
- the metal component 10 may be formed from a substantially chromium-free substrate 15 that includes any metal including, but not limited to, iron, aluminum, titanium, copper, nickel, and alloys of each of these materials, including mild steel and stainless steels.
- the metal may also include some non-metallic components.
- layer 12 and substrate 15 are substantially free of chromium content, other than a trace amount of chromium present as an impurity.
- the substantially chromium-free, silicon-containing layer 12 is formed from a substantially chromium-free, silicon-containing liquid composition that is applied to surface 14, such as by hand application with a paint brush B ( FIG. 1 ) as if being painted, by spraying in a controlled manner, or by dipping into a bath (not shown).
- the uncured fluid composition is then cured at a low temperature to form a solid or semi-solid that is bonded to the surface 14.
- the silicon-containing layer 12 may be cured by air-drying with optional heating.
- the curing temperature of the silicon-containing layer 12 is significantly less than 204 °C (400 °F).
- the fluid composition may be cured at about 121 °C (250 °F) for about 15 to 25 minutes to form the silicon-containing layer 12.
- the fluid composition forming layer 12 is substantially free of chromium content, other than a trace amount of chromium present as an impurity.
- the surface 14 may be substantially cleaned of any contaminants.
- a degreaser such as acetone, sodium hydroxide (NaOH) or potassium hydroxide (KOH) may be used to clean the surface 14 and potentially improve the bonding of the cured layer 12 to the surface.
- a biocide such as silver chloride (AgCl) may also be added to the fluid composition before layer 12 is applied to surface 14.
- a particular fluid or liquid composition that may be selected for use in forming layer 12 is a silicon-containing substance or liquid such as a silane.
- Silanes suitable for use in the present invention may have mono-, bis-, or tri-functional trialkoxy silane.
- the silane may be a bifunctional trialkoxy silyl, preferably trimethoxy, or triethoxy silyl groups.
- Amino silanes may also be used, although thio silanes may not be desired due to their sulfur content.
- Bisfunctional silane compounds are well known to persons having ordinary skill in the art, and two preferred for use in the present invention are bis(triethoxysilyl) ethane and bis(trimethoxysilyl) methane.
- silanes include, but are not limited to, 1, 2- Bis(tetramethyldisoloxanyl) Ethane 1, 9- Bis(triethoxysilyl) Nonane Bis(triethoxysilyl) Octane Bis(trimethoxysilyl Ethane 1, 3- Bis(trimethylsiloxy)-1, 3- Dimethyl Disiloxane Bis(trimethylsiloxy) Ethylsilane Bis(trimethylsiloxy) Methylsilane Al-501 available from AG Chemetall (Frankfurt Germany)
- the silane may be neat, in an aqueous solution, or diluted in an aqueous/alcohol solvent solution.
- a solvent for the latter type of diluted solution may contain from about 1% to 2% by volume to about 30% by volume deionized water with the remainder being a monohydric alcohol such as methanol, ethanol, n- or iso-propanol, or the like. Ethanol and methanol are preferred monohydric alcohols.
- the solvent is combined with the silane and glacial acetic acid to preferably establish a pH of about 4-6.
- the silane concentration in the solution may be limited to a maximum concentration for which the silane remains in solution during application. Generally, the solution will consist of about 1% to about 20% silane, wherein the percentage may be measured either by volume or by weight.
- a particularly useful silane for use in providing silicon-containing layer 12 may be an organofunctional silane such as BTSE 1,2 bis(triethoxysilyl) ethane or BTSM 1,2 bis(trimethoxysilyl) methane.
- the silane may be dissolved in a mixture of water and acetic acid at a pH of 5, then in denatured alcohol and glacial acetic acid to establish a silane solution.
- the silane concentration in the solution is between about 1% and 10% by volume and, advantageously, about 5% by volume. This silane solution readily forms the silicon-containing layer 12, which may have a more or less hard consistency, at a temperature readily achieved and insufficient to form the protective coating 16.
- the liquid composition that is applied to, after curing, form the silicon-containing layer 12 is applied in an amount of about 0.01 g/cm 2 to about 2.0 g/cm 2 .
- Multiple layers of the liquid composition may be applied; each individual layer being dried and heated to remove the solvent before applying the next successive layer.
- the silicon-containing layer 12 may refer to either the initially applied layer of liquid composition, or without limitation to the dried layer.
- the silicon-containing layer 12 may have a thickness in the range of about 40 nm to about 200 nm in the cured state and may form a continuous layer on surface 14, although the invention is not so limited.
- Silicon-containing layer 12 is heated to a temperature and for a duration effective to convert layer 12 into a substantially chromium-free, silicon-containing protective coating 16 across the portion of the original surface 14 of the metal component 10 to which layer 12 is applied.
- the conversion temperature is a temperature between 204 °C (400 °F) and about 70 percent of the melting temperature of the substantially chromium-free metal constituting component 10.
- the specific temperature to which silicon-containing layer 12 is heated to cause the conversion to protective coating 16 will depend, among other things, upon the composition and characteristics of the liquid composition used to form layer 12 and the specific metal constituting the metal component 10.
- the protective coating 16 may be continuous with a thickness measured relative to an exposed surface 24 that, after the coating 16 is applied, is exposed to the operating environment of the metal component 10.
- the protective coating 16 substantially free of chromium content, other than a trace amount of chromium present as an impurity.
- a particularly advantageous conversion temperature may be the eutectic temperature for silicon and the particular metal constituting the metal component 10.
- a eutectic or eutectic mixture is a mixture of two or more elements that has a lower melting point than any of its constituents. The proper ratio of silicon and metal to obtain a eutectic alloy is identified by the eutectic point on a phase diagram. The eutectic point is the point at which the liquid phase borders directly on the solid forms of pure silicon and the pure metal, which represents the minimum melting temperature or eutectic temperature of any possible alloy of silicon and the metal(s) constituting the metal component 10.
- the substantially chromium-free silicon-containing layer 12 may be heated in various different non-oxidizing atmospheres and under various different conditions to form the substantially chromium-free protective coating 16.
- the conversion from substantially chromium-free, silicon-containing layer 12 to substantially chromium-free, silicon-containing protective coating 16 may be accomplished by placing the metal component 10 into a heated enclosure, like an oven or furnace. However, the specific heating method may be selected based upon the size of the component 10 and the availability of heating options.
- the heated enclosure is heated to a temperature sufficient to elevate layer 12 to a temperature sufficient to cause the conversion.
- the curing step to form silicon-containing layer 12 and the subsequent step converting the cured layer 12 into protective coating 16 may be conducted in the same heated enclosure or before placing the metal component 10 into the heated enclosure.
- the silicon-containing layer 12 cures at a lower temperature than the temperature required to convert layer 12 into protective coating 16.
- the heat tunnels used in powder coaters may provide a suitable heated environment or enclosure.
- this approach may be particularly advantageous for forming the protective coating 16 on metal components composed of aluminum.
- the substantially chromium-free silicon-containing layer 12 is heated in a non-oxidizing ambient atmosphere, such as argon, to form, for example, a substantially chromium-free protective coating 16, such as a metal silicide, that contains silicon from layer 12 and a concentration of one or more elements from the constituent material of the metal component 10.
- a non-oxidizing ambient atmosphere such as argon
- the non-oxidizing ambient environment may be an oxygen-depleted environment created by evacuating atmospheric gases (air) from a heating chamber and filling the evacuated chamber with an inert gas.
- the substantially chromium-free silicon-containing layer 12 maybe applied across an existing coating 18 on substrate 15.
- the existing coating 18 may be, for example, an existing protective coating 16 that is in need of repair.
- the existing coating 18 may be stripped from surface 14 before the silicon-containing layer 12 is applied for forming the protective coating 16.
- the metal component 10 includes the protective coating 16 on the surface 14 of the substrate 15.
- the protective coating 16 protects the underlying metal of the substrate 12 of metal component 10 against, for example, oxidation and corrosion.
- the substantially chromium-free protective coating 16 may be an additive layer 20 or, more typically, may include a concentration of one or more elements from substrate 15 because of interdiffusion between the applied silicon-containing layer 12 and the metal of the substrate 15.
- the protective coating 16 will be generally characterized by a diffusion zone 22 in addition to the additive layer 20 that overlies the diffusion zone 22.
- the interdiffusion may advantageously introduce a concentration of one or more additional elements from the substrate 15 into the protective coating 16 that ultimately endow the coating 16 with beneficial protective capabilities.
- the diffusion zone 22 may be absent.
- the invention also contemplates that the silicon from the layer 12 may diffusion into the surface 14 and combine with the metal of the substrate 15 such that the original surface 14 is present after the conversion and the silicon resides entirely in a diffusion zone 22.
- the invention further contemplates that the fluid compositions described herein may be introduced into internal passages (not shown) of the substantially chromium-free metal component 10 for purposes of forming the substantially chromium-free, silicon-containing protective coating 16 on internal surfaces bordering the passages.
- the silicon-containing fluid composition is introduced into the passages to form substantially chromium-free, silicon-containing layer 12 and heated to form the protective coating 16 on these internal surfaces.
- the substantially chromium-free, silicon-containing layer 12 may be applied to a metal component 10 composed of copper by immersion in the liquid composition, preferably almost immediately after the copper component 10 is drawn to a final dimension.
- a protective coating 16 containing silicon is formed in which silicon is incorporated into copper metal as a diffusion zone 22 with an optional additive layer 20.
- the protective coating 16 may be a copper silicide layer.
- the substantially chromium-free, silicon-containing layer 12 may be applied to a metal component 10 composed of a steel.
- a metal component 10 composed of a steel.
- the application of a thin layer of silane followed by heating to a temperature less than 770°C (1418°F) but greater than 204 °C (400 °F) in a non-oxidizing environment forms a protective coating 16, which may be ferric silicide, that improves corrosion resistance.
- the solubility of the silicon in iron is less than four (4) weight percentage. In very dilute solutions less than 0.4 weight percent silicon, silicon may replace carbon in the steel.
- the existing layer 18 may be a hard chromium coating or plating that is pre-existing on the substantially chromium-free metal component 10 before the substantially chromium-free, silicon-containing layer 12 is applied.
- the silicon-containing layer 12 is heated to a temperature less than 800°C (1472°F) but greater than 204 °C (400 °F) in an inert environment to form the protective coating 16.
- the resultant protective coating 16 is not substantially free of chromium as preferred by the present invention, the chromium in coating 16 does not originate from either component 10 or layer 12 but, instead, originates from layer 18.
- the substantially chromium-free, silicon-containing layer 12 may be applied to a metal component 10 composed of aluminum, followed by heating to less than 400°C (752°F) but greater than 204 °C (400 °F) in a non-oxidizing environment, which is believed to produce a protective coating 16 of aluminum silicide.
- the solubility of silicon in aluminum is limited to a maximum of one (1) weight percent to 1.5 weight percent at the eutectic temperature of 577°C (1071°F).
- the protective coating 16 may also increase the resistivity of the metal of the metal component 10, which may represent an additional benefit of the present invention.
