Wear-resistant coatings based on niobium nitride

Abstract

The results of studies of the use of niobium nitride and its modifications as a material of wear-resistant coatings are presented. It is shown that coatings based on niobium nitride have higher values of mechanical properties. The use of such coatings changes the thermal and stress state and increases the shape stability of the cutting wedge of the tool, which reduces the intensity of wear.

“…Nonetheless, it can also be considered as a nonconventional material for cutting tool protective coatings due to its better combined thermal and mechanical properties than TiN. [ 213 ]…”

“…NbN, being an excellent superconductor, is considered as one of the most commonly preferred materials in the electronic industry. [203][204][205][206][207][208] NbN can be used in diversified areas such as biomedical, [196,209,210] fuel cells, [211,212] cutting tools, [213] optical industry, [214,215] diffusion barriers, [197] thermometry, [216,217] supercapacitors, [218] cryogenics, [219,220] etc. Nonetheless, it can also be considered as a nonconventional material for cutting tool protective coatings due to its better combined thermal and mechanical properties than TiN.…”

Synthesis of highly disperse NbSi2–Si3N4 and Si3N4–NbN composite powders

“…At the same time, in comparison with titanium nitride coatings, protective niobium nitride arc-PVD coatings demonstrate higher wear resistant. 7 Boatemaa 8 reported about the selfhealing effect of niobium nitride due to the formation of niobium oxide with a high volume expansion up to 150%. Under operation in the temperature range 1400−1800 • С, additions of MoSi 2 and NbSi 2 disilicides impart wear resistance and corrosion resistance to composites intended for use in components of engines, turbines and for other high-temperature applications.…”

“…Niobium nitride is not a traditional choice for the development of composite materials for the tribological application. At the same time, in comparison with titanium nitride coatings, protective niobium nitride arc‐PVD coatings demonstrate higher wear resistant 7 . Boatemaa 8 reported about the self‐healing effect of niobium nitride due to the formation of niobium oxide with a high volume expansion up to 150%.…”

Исследование Ультратонких Сверхпроводящих Пленок Нитрида Ниобия, Полученных Методом Атомно-Слоевого Осаждения

“…Нитрид ниобия ввиду комбинации своих уникальных физических и химических свойств имеет множество различных применений. Высокая температура плавления, химическая и механическая стойкость [1,2], относительно хорошая электрическая проводимость дают возможность использовать этот материал в качестве износостойких и биосовместимых покрытий [3,4], диффузионного барьера для создания медной металлизации [5] и электрода затвора для устройств на КМОП (комплементарная логика с транзисторами на металлоксид-полупроводнике) [6]. Также множество применений этого материала связано с его сверхпроводящими свойствами.…”
