Lubricant composition, in particular a cooling lubricant solution, based on ionic and/or organoelemental compounds.

Described herein is a stabilized lubricant composition for use in steel casting, in particular in continuous casting processes. In particular, the lubricant composition for processes for producing steel by continuous casting includes a dispersion of a lubricant powder, for an ingot mold, in continuous casting, in an oily liquid means, and a stabilization additive, characterized in that it has the following shear thinning index values:

TABLE-US-00001 RVT 0.1/1 1/10 10/100 100/1000 STI 3.0-7.5 2.0-6.5 1.0-3.0 0.5-2.0 wherein RVT is the ratio between two different shear speeds and STI is the shear thinning index corresponding to the RVT values.

The invention relates to a polyamide-based surface material having fillers which improve the tribologically active properties, wherein the fillers comprise at least one metal sulfide and/or calcium phosphate. The invention further relates to a three-dimensional molded body consisting of a surface material, produced, in particular, as an injection-molded part or extrusion part and or by additive fabrication.

The disclosure provides for a valve including a surface movably engaged with another surface. A coating is on the surface and is characterized by: a CoF of less than 0.1; a hardness in excess of 1,200 HVN; impermeability to liquids at pressures ranging from 15 and 20,000 psi; a surface finish of 63 or less; and a thickness ranging from 0.5 to 20 mils. The disclosure provides for material constructions including a continuous phase, including a transition metal, and a discontinuous phase, including a solid dry lubricant. The disclosure also provides for a method of depositing a coating that includes depositing a first layer of a coating onto a surface using electroplating, electroless plating, thermal spraying, or cladding, and then depositing a second layer of the coating onto a surface of the first layer using sputtering, ion beam, plasma enhanced chemical vapor deposition, cathodic arc, or chemical vapor deposition.

Lubricant compositions and methods of producing die-cast products by applying such a lubricant composition to a working surface of a die prior to casting a product from a molten metal injected into the die. The composition serves as lubricant between the die and resulting product, and contains at least one active component that reacts with an oxide of the metal to remove a layer of the oxide that forms on a surface of the melt during the die casting process.
