Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania spiekanych elementów o osnowie żelaza lub jego stopów, w którym ze zhomogenizowanej mieszanki zawierającej proszki żelaza lub jego stopów, dodatki lub zaprawy stopowe, środki przeciwpoślizgowe i dodatki indukujące pojawienie się cieczy, formuje się wypraski, po czym w atmosferze ochronnej nagrzewa je, spieka izotermicznie i chłodzi, polega na tym, że mieszanka przeznaczona do wytwarzania elementów spiekanych zawiera 0,05 do 1,00% wag. boru w postaci aktywnej i co najmniej jeden z azotków, z wyłączeniem azotku boru, wybranych spośród azotków mających temperaturę topnienia lub rozkładu wyższą od temperatury spiekania, a zwłaszcza azotków Si, Cr, Ti, Al, Mo, Mn, V, przy czym zawartość azotków i boru w mieszance jest tak dobrana by stosunek molowy atomów azotu do boru wynosił od 0,05 do 2,15, korzystnie 0,1 do 1,4.The subject of the application is a method for producing sintered iron or iron alloys in which a homogenised mixture containing iron powders or its alloys, additions or mortars, anti-slip agents and additives inducing the appearance of liquids, molds are formed, and then heated in a protective atmosphere eats, isothermal and cools, consists in the fact that the mixture intended for the production of sintered elements contains 0.05 to 1.00 wt. boron in active form and at least one of the nitrides, excluding boron nitride, selected from nitrides having a melting or decomposition temperature higher than the sintering temperature, in particular the nitrides Si, Cr, Ti, Al, Mo, Mn, V, the nitride content and boron in the mixture is selected such that the molar ratio of nitrogen to boron atoms is from 0.05 to 2.15, preferably 0.1 to 1.4.
