Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania warstwy azotku boru na wyrobach węglowych, zwłaszcza grafitowych, w którym nakłada się powłokę azotku boru poprzez nasycanie, charakteryzujący się tym, że nasycanie wyrobu prowadzi się w pierwszym etapie, zaś po jego zakończeniu, przechodzi się do drugiego etapu, w którym prowadzi się obróbkę jarzeniową w warunkach aktywacji elektrycznej środowiska gazowego azotu, przy czym w etapie drugim wyrób umieszcza się w reaktorze i nagrzewa się do temperatury z przedziału 700°C do 800°C, a następnie przez reaktor przepuszcza się azot przy ciśnieniu z przedziału od 2 do 5 mbar, a pomiędzy wyrobem a ścianą reaktora przykłada się różnice potencjałów wynoszącą od 400 do 1800 V w czasie wynoszącym od 240 do 360 min.The subject of the application is a method for producing a boron nitride layer on carbon products, especially graphite products, in which a boron nitride coating is applied by impregnation, characterized in that the impregnation of the product is carried out in the first stage, and after its completion, a second stage is carried out in which a glow discharge treatment is carried out under conditions of electrical activation of a nitrogen gas environment, wherein in the second stage the product is placed in a reactor and heated to a temperature in the range of 700°C to 800°C, and then nitrogen is passed through the reactor at a pressure in the range of 2 to 5 mbar, and a potential difference of 400 to 1800 V is applied between the product and the reactor wall for a time of 240 to 360 min.
