  • Method of closing a bore
    Patent number: 9539641
    Abstract: The invention relates to a method of closing a bore (3) in a metal sintered component (2), whereby, prior to sintering a preform (1) to obtain the sintered component (2) or before a step of calibrating the sintered component (2), a closing body (5) is pushed into the bore (3), and the closing body (3) has an external diameter that is either of an identical size to or at least partially larger than the internal diameter (9) of the bore (3).
    Type: Grant

  • High carbon surface densified sintered steel products and method of production therefor
    Patent number: 7722803
    Abstract: A powder mixture alloy is provided for manufacturing surface densified high carbon sintered steel articles containing iron or iron pre-alloyed powder, which has been preliminary mixed with at least 0.4 wt % graphite, lubricant and optionally at least one alloying element from the group of nickel, chromium, copper, manganese and molybdenum. Components are manufactured utilizing the alloy mixture comprising the steps of: a) compacting the metallic powder to obtain a compact; b) pre-sintering the compact at a low temperature to prevent graphite from diffusing into the iron; c) surface densifying of the pre-sintered compact to a predetermined densification depth; d) sintering under neutral gas or carburizing atmosphere; e) heat treating the sintered compact.
