It also relates to the use of this coated steel sheet or part for producing an enamelled steel sheet or part, and to a process for producing an enamelled steel sheet or part allowing a decrease of firing temperature and time compared with conventional firing temperatures and times. | ||||||
| 104 | CHEMICAL PROTECTION OF A LITHIUM SURFACE | US11944906 | 2007-11-26 | US20080113261A1 | 2008-05-15 | Lutgard De Jonghe; Steven J. Visco; Yevgeniy S. Nimon; A. Mary Sukeshini |
| Disclosed are compositions and methods for alleviating the problem of reaction of lithium or other alkali or alkaline earth metals with incompatible processing and operating environments by creating an ionically conductive chemical protective layer on the lithium or other reactive metal surface. Such a chemically produced surface layer can protect lithium metal from reacting with oxygen, nitrogen or moisture in ambient atmosphere thereby allowing the lithium material to be handled outside of a controlled atmosphere, such as a dry room. Production processes involving lithium are thereby very considerably simplified. One example of such a process is the processing of lithium to form negative electrodes for lithium metal batteries. | ||||||

| Process using the following stages in the following order: a) scouring, b) initial surface treatment in a single operation meeting three criteria relating to resistance to corrosion, lubrication and cleanability, c) shaping, d) second so-called nickeling surface treatment, e) enameling. With the aid of this order of operations and the criteria defining the initial surface treatment, scouring may be carried out on line on the installations for production of sheet-steel strips. | ||||||

| 107 | Process for treating steel sheets for the purpose of enamelling the sheets | US555923 | 1975-03-06 | US4012239A | 1977-03-15 | Charles Georges Henri Brun; Philippe Marcel Rene Tirmarche |
| For treating a steel sheet for subsequent enamelling of the sheet with one coat of enamel: After rolling the sheet, there is deposited thereon a coat of nickel and/or cobalt, a salt of said metals or mixtures of said salts. After drying, the sheet is annealed in a decarburizing atmosphere so as to substantially totally decarburize it and, during the cooling of the annealing cycle, the coated sheet is subjected to the action of an oxidizing atmosphere containing 2 to 7% of water vapor and having an H.sub.2 /H.sub. 2 O ratio which is less than 6. | ||||||
| 108 | Direct-on ceramic coating of carbon-rich iron | US608961 | 1975-09-02 | US3971120A | 1976-07-27 | Clifford G. Ruderer |
| A process is disclosed for preparing an iron workpiece containing at least 0.03% by weight carbon for a direct-on, one-fire ceramic or enamel coat. A substantially continuous layer of substantially pure iron is pressure-bonded onto a surface of the carbon-rich iron workpiece. Thereafter, the workpiece and bonded iron layer are placed in an electroconducting liquid medium and, while using the workpiece as an anode, some of the deposited iron is electrolytically removed to produce an exposed, fissured, textured surface in the pure iron layer. When a ceramic coat is conventionally applied over the fissured surface, it adheres well, even though the iron workpiece may contain appreciable amounts of carbon which normally prevent such adherence for a direct-on ceramic coat. Optionally, the pressure-bonded layer may be followed by an electrodeposit of a porous, substantially pure iron layer prior to applying a ceramic coat. | ||||||
| 109 | Preparation of nickel and chromium substrates for ceramic coating | US436180 | 1974-01-24 | US3962490A | 1976-06-08 | Rodney L. Ward |
| A process and product are disclosed relating to the preparation of a metallic substrate of a workpiece for a subsequent deposition of a ceramic coating, such as porcelain enamel, in which the metal of the substrate is one that is not sufficiently electrochemically active to be coated by electrophoresis, for example, stainless steel or those alloys containing principally nickel and/or chromium. In one form, the metallic substrate is first covered with an oxide, and preferably a thermally decomposable compound, of a transition metal selected from Groups IIIB through Group IIB of the Periodic Table of The Elements. The workpiece is then heated to alloy the transition metal with the substrate of the workpiece, after which a ceramic coat may be applied. When the transition metal is present as a thermally decomposable compound, the compound must decompose prior to reaching an alloying temperature. | ||||||
| 110 | Direct-on ceramic coating of carbon-rich iron | US53544174 | 1974-12-23 | US3923611A | 1975-12-02 | RUDERER CLIFFORD G |
| A process is disclosed for preparing an iron workpiece containing at least 0.03% by weight carbon for a direct-on, onefire ceramic or enamel coat. A substantially continuous layer of substantially pure iron is electrodeposited on a surface of the carbon-rich iron workpiece from a liquid medium containing iron ions while using the workpiece as a cathode. The polarity of the electrodeposition is then reversed to remove some of the iron deposited and produce an exposed, fissured, textured surface in the pure iron layer. When a ceramic coat is conventionally applied over the fissured surface, it adheres well, even though the iron workpiece may contain appreciable amounts of carbon which normally would prevent such adherence for a direct-on ceramic coat. Optionally, the cathodic deposition of iron may comprise a deposition of a non-porous layer followed by an overlay of porous iron and/or take place from an aqueous medium having an acidic pH. A film of a covering metal such as nickel may also be deposited over the fissured layer prior to depositing the ceramic coat.

| 111 | Process for preparing steel for enameling | US36060873 | 1973-05-15 | US3911177A | 1975-10-07 | HUMBERT MAURICE; STREEL DOMINIQUE |
| Low carbon steel having less than 0.012% carbon, is prepared for enameling by degreasing and rinsing, then heating the steel to 200* to 800*C. and depositing thereon by vacuum evaporation an alloy of iron with another Group VIII metal such as nickel or cobalt, the nickel or the like being present in the alloy in an amount 1 to 15% and preferably 4 to 8% by weight, balance iron, and being present on the steel in an amount 0.5 to 4 grams per square meter and preferably 1 to 3 grams per square meter. The previous need to pickle the steel between degreasing and enameling is thus eliminated, and the number of steps and the cost of equipment and operation is reduced.

| An improved surface on sheet steel having a carbon content below 0.01%, preferably below 0.003%, for subsequent porcelain enameling or the deposition of a metal or organic, e.g., paint, coating thereon or in preparation of the sheet steel for a subsequent laminating operation, is provided by subjecting the sheet steel having a carbon content below about 0.1% by weight to oxidation in the presence of air under conditions to build up on the surface of the sheet steel undergoing oxidation an oxide layer having a thickness in the range 0.1-1.5 mils and such that the oxidized sheet steel exhibits a gain in weight of at least about 0.5 grams per square foot of oxidized surface, followed by subjecting the resulting oxidized sheet steel to reduction in an atmosphere consisting essentially of nitrogen and hydrogen, preferably at a temperature isothermal with the aforesaid oxidation temperature, such as at a temperature in the range 1000*-1500*F., to reduce substantially all of the oxide layer to metal and then subjecting the resulting oxidized-reduced sheet steel to decarburization at a temperature in the range 1000*1500*F. in an atmosphere consisting essentially of nitrogen, hydrogen and water vapor.

| FUSIBLE PORCELAIN IS UNITED IN A THIN LAYER TO A PRECIOUS METAL BASE MEMBER BY FIRST FORMING ON SUCH PRECIOUS METAL BASE MEMBER A GOLD COAT HAVING A CARPET-LIKE, IRREGULAR SURFACE COMPOSED OF GOLD PARTICLES WHICH ARE SOLDERED OR SWEATED TO THE BASE MEMBER AND ARE LATERALLY SEPARATED FROM EACH OTHER, AND THEN APPLYING TO SUCH CARPET-LIKE, IRREGULAR SURFACE A PASTE OF A RELATIVELY LOWFUSING PORCELAIN WHICH UPON BEING FUSED IN SITU IS MECHANICALLY UNITED TO SAID CARPET-LIKE SURFACE BY INTERLOCKING TO SUCH GOLD PARTICLES. THE INTERLOCK THUS FORMED OF THE PORCELAIN LAYER WITH THE PURE GOLD PARTICLES HAS BEEN FOUND TO PERMIT OF LIMITED DIFFERENTIAL EXPANSION AND CONTRACTION BETWEEN THE PORCELAIN LAYER AND THE BASE MEMBER UNDER THE SAME HEAT CONDITIONS DUE TO THE FACT THAT THE PURE GOLD PARTICLES YIELD WITH MOVEMENT OF THE PORCELAIN. THERE IS ALSO PROVIDED TH NOVEL COMPOSITE STRUCTURE OF A PRECIOUS METAL BASE MEMBER, A GOLD COAT LAYER HAVING SPACED GOLD PARTICLES SOLDERED OR SWEATED T THE BASE MEMBER, AND A PORCELAIN LAYER INTERLOCKED TO SUCH GOLD COAT PARTICLES.
