Leonid M. Buchatsky has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Apparatus for making products from powdered materials
    Patent number: 5308232
    Abstract: The invention relates to powder metallurgy. The invention involves deforming combustion products by extrusion at an extrusion temperature chose in the range from 0.3T.sub.1 to T.sub.2, wherein T.sub.1 is the melting point of a hard phase of the combustion products and T.sub.2 is the melting point of a binder material in a container (5) made up of vertically extending segments (12) defining spaces (13) with one another and having a die (14) and a heat insulated sizing member (17) the temperature conditions of extrusion being controlled by a unit (21) having a temperature sensor (22) and a member (23) receiving information from the sensor (22) and sending a command for moving the punch (10).

    Filed: July 25, 1991
    Date of Patent: May 3, 1994
    Assignee: Institut Strukturnoi Makrokinetiki Akademii Nauk SSSR
    Inventors: Alexandr G. Merzhanov, Alexandr M. Stolin, Vadim V. Podlesov, Leonid M. Buchatsky, Tatyana N. Shiskina
  • Exothermic process for the production of molybdenum silicide composites
    Patent number: 5149677
    Abstract: The invention relates to the production of a new ceramic composite material containing molybdenum disilicide in the form of 20-60 .mu.m grains.The method involves preparation of an exothermic mixture containing silicon, molybdenum (VI) oxide, aluminium and molybdenum with the following ratio of the components (wt %):______________________________________ silicon 29-38 molybdenum (VI) oxide 7-42 aluminium 3-16 molybdenum 13-52 ______________________________________its heat treatment in a combustion mode, followed by compaction of the obtained combustion products by way of at least two-stage compression with a degree of deformation from 0.75 to 0.90 at each stage, at a temperature within 1500.degree. to 1900.degree. C.
