  • METHODS FOR PRODUCING LOCALLY HARDENED COMPONENTS
    Publication number: 20260185175
    Abstract: A method for producing a locally hardened component is provided. The method includes S1: placing a to-be-heated portion of a base component in an induction coil for induction heating to form a heated portion; S2: after a completion of the induction heating, spraying a quenching solution on the heated portion, cooling the heated portion down to room temperature, removing the base component, and tempering the base component at low temperature to obtain a quenched component; and S3: grinding, degreasing, and drying a hardened portion of the quenched component, coating a surface treatment solution on a surface of the hardened portion, curing the surface treatment solution, and performing an induction cladding on the hardened portion in a nitrogen atmosphere to obtain the locally hardened component.

  • DATA EVENT SENDING METHOD AND APPARATUS AND EVENT PROCESSING SYSTEM
    Publication number: 20090228903
    Abstract: The present invention is directed to an apparatus, system, methods, and computer-program product for sending a data event so that a work flow event can be correlated with a data event. According to one embodiment of the invention, a data event sending apparatus can be provided. The apparatus can include a receiver for receiving data revised by a node from which a work flow event is emitted, a formatter for obtaining correlation information on the work flow event according to predefined logic for the revised data, and for formatting the revised data and the correlation information to obtain a data event, and a sender for sending the data event.
