METHODS FOR PRODUCING ALLOY DEPOSITS AND CONTROLLING THE NANOSTRUCTURE THEREOF USING NEGATIVE CURRENT PULSING ELECTRO-DEPOSITION, AND ARTICLES INCORPORATING SUCH DEPOSITS

Bipolar wave current, with both positive and negative current portions, is used to electrodeposit a nanocrystalline grain size deposit. Polarity Ratio is the ratio of the absolute value of the time integrated amplitude of negative polarity current and positive polarity current. Grain size can be precisely controlled in alloys of two or more chemical components, at least one of which is a metal, and at least one of which is most electro-active. Typically, although not always, the amount of the more electro-active material is preferentially lessened in the deposit during times of negative current. The deposit also exhibits superior macroscopic quality, being relatively crack and void free. Parameters of current density, duration of pulse portions, and composition of the bath are determined with reference to constitutive relations showing grain size as a function of deposit composition, and deposit composition as a function of Polarity Ratio, or, perhaps, a single relation showing grain size as a function of Polarity ratio. A specified grain size can be achieved by selecting a corresponding Polarity Ratio, based on these relations. Coatings can be in layers, each having an average grain size, which can vary layer to layer and also in a region in a graded fashion. Coatings can be chosen for environmental protection (corrosion, abrasion), decorative properties, and for the same uses as a hard chrome coating.

Hybrid steel wire cord for tyres

FIELD: tyre industry. SUBSTANCE: invention relates to steel wire cords designed for reinforcement of plastic and/or rubber articles, for instance, automobile tyres. Said hybrid steel wire cord incorporates at least one stainless steel core in contact with one or several cord cores made of carbon steel. Microstructure of stainless steel comprises less than 20% of martensite by volume. Use of stainless steel core in steel cord containing carbon steel cores provide longer service life and increases corrosion resistance of cord.

Hardfacing alloy, methods, and products

Disclosed is a hardfacing alloy capable of withstanding service abrasion of the order of silicious earth particles and weldable on industrial products, such as tool joints and stabilizers used in oil and gas well drilling, and other industrial products. The hardfacing alloy has a low coefficient of friction resulting from excellent metal to metal resistance and significant reduction in industrial wear on industrial products, such as casing wear. Other embodiments of the invention include tool joints having the hardbanding alloy welded to the outer cylindrical surface to its box and pin members and to stabilizer ribs on the stabilizer used in earth boring, such as boring for oil and gas, other industrial products, and methods of applying the hardfacing alloy to their surfaces. The hardfacing alloy does not require any post weld treatment, has primary borides in its microstructure, the carbons in the alloy are tied up in the formation of secondary carbides which add to the abrasion resistance, and have a quadratic crystallographic structure and a hardness of about 1725 Hv comparable to the prior art hardness of the chromium carbide primary carbide alloys of the prior art but is substantially less brittle than C—Cr—Fe hardfacing alloys.

Metal pretreatment composition containing zirconium, copper, and metal chelating agents and related coatings on metal substrates

Disclosed is a zirconium-based metal pretreatment coating composition that includes a metal chelator that chelates copper in the metal pretreatment coating composition and thereby improves adhesion of paints to a metal substrate coated with the pretreatment coating composition. The pretreatment coating composition has a longer pot life than one without the metal chelator and therefore can accommodate a wide latitude of application times. The chelating agent is present in a sufficient amount to ensure that in the deposited pretreatment coating on the metal substrate the average total atomic % of copper to atomic % of zirconium is equal to or less than 1.1. The pretreatment coating composition is useful for treating a variety of metal substrates.
