Abstract

A metal compact is formed of a matted and sintered mass of metal fibres, the fibres being united by autogenous bonds at their junctions, the sintered skeleton having been subsequently treated with a substance of different composition from that of the fibres so as to at least partially coat and fill the pores of the skeleton. The subsequent treatment may consist of impregnating with liquid metals or alloys, e.g. a stainless steel fibre skeleton may be impregnated with molten magnesium, steel or molybdenum fibre skeletons impregnated with babbitt metal, ferrous fibre skeletons with copper, or tungsten carbide with cobalt, nickel or their alloys. The skeleton may be impregnated with comminuted metals or alloys, e.g. molybdenum skeletons impregnated with silver copper or aluminium powder, stainless steel with magnesium powder or ferrous skeletons with copper powder. The metal skeletons may be impregnated with carbonaceous or resinous compounds. Thus polytetrafluorethylene may be used in stainless steel or molybdenum skeletons or nylon in iron or bronze. Carbonizable compound fillers may be carbonized to give a metal skeleton impregnated with carbon. The skeletons may be impregnated with inorganic non-metallic materials such as alumina silicon or silicon carbide or liquid silicates. Skeletons may be reacted with gases or vapours, e.g. ferrous skeletons may be nitrided or surface alloyed with the product of decomposition of volatile halides or carbonyls. In examples a steel skeleton formed by sintering in dry hydrogen at 2400 DEG F. was impregnated with molten magnesium at 1375 DEG F. in argon or hydrogen, stainless steel fibres compressed at 30 tons/in2 and sintered in dry hydrogen at 2400 DEG F. were impregnated with polytetrafluorethylene. Molybdenum fibres pressed at 40 tons/in.2 and sintered in dry hydrogen for 1 hour at 1900 DEG F. were impregnated with molten sulphur by simple immersion or vacuum impregnation. Silver fibres may be similarly sintered and impregnated with sulphur. Specifications 821,690 and 844,937 are referred to.
