Abstract:
In order to obtain a cold rolled steel sheet having excellent press formability, a cold rolled steel sheet has, on a surface thereof, an organic-inorganic composite film containing: an organic resin; and a crystalline layered material. The organic-inorganic composite film has an average film thickness of 0.10 to 2.0 μm and contains 0.5 part or more by weight of the crystalline layered material as a solid with respect to 100 parts by weight of a solid of the organic resin. The crystalline layered material preferably is, for example, a layered double hydroxide represented by [M2+1-xM3+x(OH)2] [An−]x/n.zH2O, where: M2+ is one or more of Mg2+, Ca2+, Fe2+, Ni2+, and Zn2+; M3+ is one or more of Al3+, Fe3+, and Cr3+; and An− is one or more of OH−, CO32 , Cl−, and (SO4) 2−.

Abstract:
A method and chemical composition and material structure for improving fretting wear in substrates, particularly carbon-carbon composite (CCC). The invention relates to trilayer coatings, comprising a base of hard ZrO2, a middle layer of Al2O3, and atop layer of lubricious ZnO. The coatings of the present invention exhibit conformality and pore-filling down to approximately 100 microns into a carbon-carbon composite to which they are applied. The methods for preparing the coatings include a chemical vapor infiltration route, such as an atomic layer deposition (ALD) process, to uniformly and conformally coat the porous and open structure of CCC with a solid lubricant trilayer of ZnO/Al2O3/ZrO2 that results in significant improvement (65%) in fretting wear.

Abstract:
In one embodiment, a substrate, for example a tool used in hot metalforming operations, is coated with an enamel nanoparticulate graded coating. The nanoparticles in the coating may be boron nitride nanoparticles. The coating may include a first portion adjacent a surface of the substrate, and a second portion adjacent the first portion. The first portion of the coating may have a lower volume fraction of nanoparticles than the second portion. The first portion has excellent adhesion to the surface of the substrate, and the second portion reduces friction and wear. The coated tool may be formed by applying at least one layer of a coating mixture to a surface of the tool and heating the coating mixture. A metal workpiece may be formed into an article by contacting the metal workpiece against the coated surface of the tool.

Abstract:
An improved oil composition is disclosed. The oil composition includes a base oil comprising a hydrocarbon, the base oil having a base thermal conductivity. The oil composition also includes a first additive comprising a plurality of derivatized first additive nanoparticles dispersed within the base oil to form a modified oil having a modified thermal conductivity, wherein the modified thermal conductivity is greater than the base thermal conductivity. Alternately, an improved oil composition includes a base oil comprising a hydrocarbon and a first additive comprising a plurality of derivatized first additive nanoparticles dispersed within the base oil to form a modified oil comprising a stabilized suspension of the derivatized first additive nanoparticles in the base oil.
Abstract:
There is provided a lubricant composition which includes: a first particle having a spherical shape having a diameter of 1 to 300 nm, having a Mohs hardness of 5 or more, at an amount of 0.01 to 40 weight %; and a second particle, having a diameter of 500 nm to 50 μm, having a Brinell hardness of 17 HB or less, at an amount of 0.01 to 40 weight %. The lubricant composition can form a bearing structure when the lubricant composition is subjected to an extreme pressure. The second particles are deformed into a retainer for the first particle.
Abstract:
A method for treatment of bacterial infections with rifalazil administered once-weekly, or twice-weekly. A method for treatment of tuberculosis caused by Mycobacterium tuberculosis, infections caused by Mycobacterium avium complex, infections caused by Chlamydia pneumoniae and infections caused by Helicobacter pylori by administering to a patient suffering from the bacterial infection 1-100 mg of rifalazil once or twice a week. In this dose regimen, the treatment is fast, efficacious and eliminates undesirable secondary symptoms observed with daily doses of 1-50 mg of rifalazil.
