Abstract

558,182. Sintered iron alloys. BRITISH PISTON RING CO., Ltd., TWIGGER, T. R., and JUDD. J. A. March 9, 1942, No. 3036. [Class 82 (i)] [Also in Group XXII] Valve seal inserts and piston ring carriers are made by pressing a predetermined quantity of metal powder in which soft iron predominates, in a die with or without the application of heat and sintering the resulting compact either in the die or after removal therefrom. During the process the article may be impregnated by immersion in oil. Commercially pure iron powder may be employed or to increase the hardness &c. alloy additions may be made for example to make percentage compositions carbon 1.5 to 4, chromium 1.5 to 10 and molybdenum 1.5 to 10. In any composition within the above ranges silicon up to 4 and manganese up to 2 may also be present and graphite &c. may be incorporated to facilitate pressing. When the article is a valve seating to be pressed into an aluminium cylinder block or head an austenitic structure and a high coefficient of expansion may be required, and a typical composition may be (percentages) total carbon 2.5, nickel 12, copper 6, manganese 1, and chromium 3. Ranges for these materials are quoted. The remainder is iron with silicon up to 4 and if desired vanadium or tungsten up to 5 each. In addition to normalising after repressing when this is necessary, further heat treatment such as quenching from over 500‹C. may be given. Only part of the valve seating may be made in this way being pressed on to a copper plated blank of other metal. Specifications 497,871 and 538,227. are referred to.
