A lubrication method including lubricating a sliding member which contains at least one selected from the group consisting of a liquid crystal polymer and polyetheretherketone by using a lubricating oil composition which contains an ester as a lubricating base oil.

Lubrication method

A lubrication method including lubricating a sliding member which contains at least one selected from the group consisting of a liquid crystal polymer and polyetheretherketone by using a lubricating oil composition which contains at least one selected from the group consisting of a mineral oil and alkyl benzene as a lubricating base oil.

A surface protection composition which is hard to deform or flow even placed under environments of a large temperature change with an external physical load such as pressure, and which stably protects a metal surface. A terminal fitted electric wire coated with the composition. The surface protection composition contains a high-consistency material (A) containing a lubricant base oil and an amide compound, and a phosphorus composition (B). The phosphorus composition (B) contains a composition (b1) containing one or more compounds represented by the general formulae (1) and (2) and one or more metals and/or one or more amines. The phosphorus composition (B) also contains one or more compounds (b2) represented by the general formula (3).

Surface protection composition and terminal fitted electric wire

An anticorrosive agent including: a high-consistency material having a lubricant base oil and an amide compound, a composition of a phosphorus compound comprising one or more compounds represented by the general formulae (1) and (2) and a metal, and at least one kind of resin selected from a rosin-based resin, a terpene resin, a terpene phenol resin, a phenol resin, a coumarone-indene resin, and a petroleum resin, wherein a mass ratio of the high-consistency material and the composition is within a range of 50:50 to 98:2, and a content of resin is 2 to 20 parts by mass with respect to 100 parts by mass of the total of the high-consistency material and the composition.

Anticorrosive agent and terminal fitted electric wire

A metal surface coating composition including a high-consistency material containing a lubricant base oil and an amide compound, and a composition of a phosphorus compound containing one or more compounds represented by the below formulae and a metal, wherein the ratio (a/b) of the number of amide groups (a) and the number of acidic groups (b) is within a range of 1.1 to 6.0: 

Metal surface coating composition and terminal fitted electric wire

A metal surface coating composition and a terminal-fitted electric wire which is anti-corrosion treated with the composition are provided. The composition includes a high-consistency material containing a lubricant base oil and an amide compound, a composition of a phosphorus compound containing one or more compounds represented by the below formulae and a metal, and a nucleating agent:  where Xto Xeach represent an oxygen atom or a sulfur atom, Rto Reach represent a hydrogen atom or a hydrocarbon group having 1 to 30 carbon atoms, among which at least one is a hydrocarbon group having 1 to 30 carbon atoms, and Rto Reach represent a hydrogen atom or a hydrocarbon group having 1 to 30 carbon atoms among which at least one is a hydrocarbon group having 1 to 30 carbon atoms.

Provided are both a grease composition for an electric power steering device and an electric power steering device. The grease composition can keep a sufficiently low coefficient of friction in a sliding area between a steel and a resin over a long period, is less susceptible to being removed from the sliding area, does not cause break down of an oil film, and thus can minimize the occurrence of stick-slips. A grease composition for an electric power steering device, containing a synthetic hydrocarbon oil which exhibits a density of 0.75 to 0.95 g/cmat 15&#xb0; C., a saturated aliphatic amide compound, boron nitride, a glycerin fatty acid partial ester, and a metal soap-based thickener; and an electric power steering device using the grease composition.
