| 20100189891 | Method of strengthening tool material by super-deep penetration of reinforcing particles for manufacturing a composite tool material - 1. A method of strengthening the matrix of a high-speed steel for forming a composite tool material by super-deep penetration of reinforcing particles into and through the matrix of the tool material. The particles interact with the matrix in the form of a high-speed jet generated and energized by an explosion of an explosive material that contains the premixed powdered components of the working medium composed of particles of a hard material and ductile metal, and if necessary, with an addition of a process liquid. The particles of the working medium material have dimensions ranging from 1 to 100 μm. The jet has a pulsating nature with the velocity in the range of 200 to 600 m/sec and a temperature in the range 100 to 2000° C. As a result of strengthening, the steel matrix is reinforced by elongated zones of the working material particles which are oriented in the direction of the jet and occupy less than 1 vol. % of the matrix material, while less than 10 vol. % is occupied by the zones of the matrix restructured as a result of interaction with the particles of the super-high velocity jet. | 07-29-2010 |
| 20100144966 | Liquid oligomer composition containing hydroxyamine adducts and method of manufacturing thereof - Proposed is a liquid oligomer composition that contains a hydroxyamine adduct and a liquid reacting oligomer. The hydroxyamine adduct includes an epoxy-amine adduct, which contains at least one primary amine group that is a product of the reaction of an epoxy compound with at least one terminal oxyrane group and at least one amine that contains at least two primary amino groups. In order to form the epoxy-amine adduct, 1 to 15 moles of at least one amine are reacted per equivalent of the aforementioned epoxy compound. The composition also contains at least one compound with one or more terminal cyclocarbonate groups. A method of manufacturing a liquid oligomer composition on the basis of the above compounds is also proposed. | 06-10-2010 |
| 20100144929 | Liquid solventless synthetic-rubber-based composition - A synthetic-rubber-based composition that consists of a low-molecular-weight rubber selected from polybutadiene comprising about 75% to about 92% cis-1,4 units, sulfur, a vulcanization accelerator, and an active filler wherein the sulfur, accelerator, and active filler are each present in the form of powder having a particular particle-size range. Additionally, this composition may be used to form coatings and rubber concretes. | 06-10-2010 |
