Zirconium Nitring in a Closed Reaction Space

Currently there are methods for zirconium nitriding at high temperatures (1300-2000 C) and long-term exposure (up to 24 hours). This paper aims at developing a novel method of zirconium nitriding at lower temperature and exposure time, while maintaining such satisfactory mechanical properties as coating and matrix. Nitriding was conducted at 900 C for about 2 hours in an atmosphere of technically pure nitrogen. Samples were placed in the reaction chamber, which could provide the necessary degree of tightness and vacuum.
