Abstract:
A composite sliding structure having a low friction coefficient and high wear resistance. The composite sliding structure (1) has segment structure hard films (2) placed, with hard films separated from each other, on the surface of a base substance (4), a segment groove (5) formed between the individual segment structure hard films (2, 2), and solid lubrication layers (3) placed in a covering manner in the segment grooves (5) or fluid-like lubrication layers (3') placed in an impregnated manner in the segment groves (5). Further, a method of producing the composite sliding structure (1) is performed by forming, in a covering manner, the segment structure hard films (2) on the surface of the base substance (4) by using a physical vapor-phase growth method or a chemical vapor-phase growth method, and covering the segment grooves (5), provided between the segment structure hard films (2, 2) with intervals in between, with the solid lubrication layers (3) or impregnating the fluid-like lubrication layers (3') in the segment grooves (5).
Abstract:
A composition and method for providing a wear-resistant and fuel-saving coating on metals, particularly metal surfaces within internal combustion engines. A source of ammonium ions, an alkali metal in an aqueous medium, and the coating metal to be applied to the surface are combined to produce an electrolyte solution comprising a complex ion mixture. The electrolyte solution can be used to deposit the coating metal on conductive substrates. The coating metal may comprise phosphorus, sulfur, carbon, bismuth, boron, silicon, and combinations thereof. The electrolyte solution can be dehydrated in a hydrocarbon medium, thus providing novel materials for use as lubricating oil additives and as fuel additives. These new surfaces may significantly reduce coefficient of friction, smooth the flame front, reduce corrosion, enhance fuel economy, and reduce hydrocarbon emissions when used in internal combustion engines.
Abstract:
The aim of said invention is to produce, during operation, a protective metalloceramic film having a heterogeneous structure and provided with increased density, wear resistance, a high adhesion to a friction surface and whose friction factor after burnishing is equal to or less than 0.03-0.07. The novelty of the inventive cladding concentrate comprising a powdery metallic filler, surface-active agents, oil-soluble metallic dialkyl-thiophosphpric acid salts and a basic oil lies in that said concentrate additionally comprises a mineral silicate and a cyclohexanol-based filler at the following component ratio: 0.05-20 % by mass of a powdery metallic filler, 0.5-11 % by mass of surface-active agents, 1-45 % by mass of metallic dialkyl-thiophosphpric acid salts, 1.2-20 % by mass of a silicate based filler and 0.05-2.0 % by mass of a cyclohexanol. Said silicate based filler comprises natural minerals selected from the range of laminated hydrocylicates such as a serpentinite and/or a chlorite. The metallic dialkyl-thiophosphpric acid salts are embodied in the form of zinc and/or stannum and/or molybdenum and/or aluminium and/or copper and/or cadmium salts.
Abstract:
A composition comprises a sulphur free reaction product of: (a)(i) a hydrocarbyl substituted aromatic compound containing an acidic group selected from the group consisting of a carboxylic group, a hydroxyl group and mixtures thereof; and (a)(ii) an organic nitrogen-containing base reacted with the acidic group. The composition is obtained by a preparatory process and is useful in a method for lubricating an internal combustion engine to include where the lubricant has reduced levels of sulphur, phosphorus and sulphated ash.
Abstract:
According to the invention there is provided a method of reducing wear of one or both of two steel elements having surfaces in sliding or sliding-rolling contact. The method involves applying an HPF friction control composition to one, or more than one contacting surface of one or both of the two steel elements. In a particular example, the HPF friction control composition comprises a rheological control agent, a lubricant, a friction modifier, and one, or more than one of a retentivity agent, an antioxidant, a consistency modifier, and a freezing point depressant.
Abstract:
In the cold drawing of steel tubing, an excellent lubrication which permits drawing the tubing while retaining its original metallic luster can be achieved by first contacting the surfaces of the tubing, both exterior and interior, with a colloidal titatium containing aqueous composition, drying the tubing, and then applying to the surface of the tubing a liquid lubricating composition comprising (i) from 40 to 95 % of a first component selected from the group consisting of olefin/oil or olefin/fat compounds which contain from 23 to 30 % of sulfur and olefin/higher ester compounds which contain from 23 to 30 % sulfur, including mixtures of two or more chemical species meeting this description; and (ii) from 5 to 50 % of a second component selected from the group consisting of oil soluble polymer compounds, fats and oils, synthetic oils, mineral oils, higher fatty acids, and the amine salts of higher fatty acids.
Abstract:
Contact of acid or alkaline cleaned aluminum surfaces, particularly cans, with a water based composition containing a combination of (i) alkoxylated phosphate esters, (ii) ions of aluminum, zirconium, iron, tin, and/or cerium, (iii) a metal etching component, and (iv) a combination of alkoxylated alcohol and alkoxylated alkyl phenol emulsifiers, gives the surface after drying lowered surface friction without loss of high quality printability and lacquer adhesion and removes any brown spotting on the cans that may have developed during the cleaning or post-cleaning rinses. The cans after treatment are substantially free from any water breaks when rinsed with water. The foaming resistance and storage stability of the water based composition as described above, and of other similar surface friction reducing treatments for aluminum containers, may be advantageously increased by adding a biocidal agent, preferably hydrogen peroxide, and a combination of liquid paraffin, solid wax, and a high molecular weight fatty acid derivative(s) as antifoam agent.
