摘要:
A water-based coolant contains: at least one inorganic acid salt selected from among carbonate, hydrogen carbonate, sesquicarbonate, phosphate, borate, molybdate and tungstate; and a metal corrosion inhibitor. The water-based coolant is excellent in cooling performance and unlikely to cause corrosion of a metal material to be cooled. Therefore, the water-based coolant is suitably usable as a quenchant or a cutting oil.

摘要:
[Task] In a sliding member comprising a substrate and a coating layer provided thereon, the coating layer has a sliding surface and is formed of a resin-based coating and particles of a solid lubricant dispersed therein. The orientation ratio of (001) plane of the solid lubricant is enhanced. [Means for Solution] The coating layer of a sliding layer has an average thickness of 3 µm or less. The particles of the solid lubricant have 2 µm or more of an average particle diameter as measured by the laser diffraction method. The solid lubricant dispersed has 90% or more of relative C-axis intensity ratio.
摘要:
A composition that includes solid lubricant nanoparticles and an organic medium is disclosed. Also disclosed are nanoparticles that include layered materials. A method of producing a nanoparticle by milling layered materials is provided. Also disclosed is a method of making a lubricant, the method including milling layered materials to form nanoparticles and incorporating the nanoparticles into a base to form a lubricant.
摘要:
The present invention relates to a solid film lubricant system useful in coating a metal, ceramic or polymeric material wear surface, comprising
i) a carrier, ii) solid lubricant components, iii) additives.
Such AF coatings, being high-grade lubricants, generally provide maintenance-free, permanent lubrication, and they are capable of meeting extreme requirements which the usual lubricants cannot meet.
摘要:
In a refrigerant compression type refrigerating system for use in the field of refrigerating/air conditioning employing a hydrocarbon refrigerant containing an odorant, the concentration of the odorant at the time of refrigerant leakage is kept on a sensible level. The refrigerant composition contains at least one ingredient selected among ethane, propane, cyclopropane, propylene, and isobutane. It contains ammonia in an amount of 1 to 60 wt. %, preferably 1 to 20 wt. %, as an odorant.

The invention relates to solid lubricants and a solid lubricant combination with a tin sulphide and carbon base, to a method for producing them and to their use in friction pad mixtures and friction pads such as brake pads or clutch linings.
摘要:
Magnesium hydroxide or mixtures of magnesium hydroxide and boron nitride applied, e.g., by spraying in a liquid vehicle onto surfaces of a sheet (22) of a superplastic formable metal alloy facilitate the forming of such sheet material and the removal of the formed sheet material from the forming tool or die (10).
