The composite material is characterized by having a porosity between about 10 % and about 40 %. The amount of the hallow nanoparticles in the composite material is 1-20 wt.%.
Abstract:
The present invention relates to lubricant compositions and can be used for treatment of friction units in different machines and mechanisms in manufacturing processes, the purpose of which is modification of friction surfaces. The basis of the invention is the improvement of lubricant composition, in which as the consequence of the additional use of thickener and wax, the viscosity of lubricant composition sufficient for conversation of uniform distribution of solid component in lubricant composition in broad temperature range is provided; and at the expense of that, the possibility of conservation of lubricant composition in any packaging and bulks, which are usable even under operating conditions of machines and mechanisms, is reached. The lubricant composition acquires the state of gel, that is convenient to put on any friction surface, to deposit on a zone of friction of any friction units. The lubricant composition ensures the receiving of engineering results similar to those, which solid components exhibit using fine-dispersed powder on basis of natural minerals from flaky silicates series and at the same time the sedimentation properties of lubricant composition permit its continuous conservation in broad temperature range without variation of lubrication and modification properties.

The solid lubricant having from about 25% to about 70% by volume of a biopolymer polymeric carrier, about 5% to 75% percent by volume of organic and inorganic extreme pressure additives, about 0% to 20% by volume synthetic extreme pressure anti-wear liquid oil, and about 0% to 1% by volume optical brightener.
Abstract:
The invention relates to a method for preparing metal workpieces for cold forming by first applying a phosphate layer and then applying a lubricant layer which has a major content in organic polymer material. The phosphate layer is formed by an aqueous acidic phosphating solution having a major content in calcium, magnesium or manganese and phosphate. The lubricant layer is formed by contacting the phosphated surface with an aqueous lubricant composition which has a content in organic polymer material based on ionomer and optionally also non-ionomer the organic polymer material used predominantly being monomers, oligomers, co-oligomers, polymers or copolymers based on ionomer, acrylic acid/methacrylic acid, epoxide, ethylene, polyamide, propylene, styrene, urethane, the ester or salt thereof. The invention also relates to the corresponding lubricant composition, to the lubricant layer produced thereof and to its use.
