Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania dyfuzyjnych warstw utlenianych na podłożu z litego tantalu i jego stopów, charakteryzujący się tym, że obejmuje następujące etapy: a) podłoże będące litym tantalem lub stopem na bazie tantalu poddaje się ogrzewaniu w elektrycznym piecu w temperaturze w zakresie do 500°C, po czym b) prowadzi się proces utlenienia powierzchni podłoża w atmosferze powietrza w czasie do 10 godzin, a wytworzony produkt chłodzi się do temperatury pokojowej w atmosferze powietrza.The subject of the application is a method of producing diffusion oxidized layers on a substrate made of solid tantalum and its alloys, characterized in that it comprises the following steps: a) the substrate being solid tantalum or a tantalum-based alloy is subjected to heating in an electric furnace at a temperature in the range of up to 500°C, and then b) the process of oxidizing the surface of the substrate is carried out in an air atmosphere for up to 10 hours, and the produced product is cooled to room temperature in an air atmosphere.
