Structure and Properties of Boride Coatings Synthesized from Thermo-Reactive Powders during Electron-Beam Surfacing

Abstract

The wear resistant composite coatings on the basis of titanium borides, which are synthesized from thermoreactive powder components of a boron-containing mixture at electron beam surfacing, are interesting for applications today.

Wytwarzanie powłok i modyfikacja powierzchni przy użyciu wiązki elektronów w spawalnictwie

“…Jedną z wielu zalet procesu napawania wiązką elektronów przy użyciu proszku jest możliwość precyzyjnego dozowania materiału dodatkowego i regulacja grubości otrzymanych warstw. W pracy [12] przedstawiono wyniki procesu napawania wiązką elektronów proszkami FeB+FeTi stali w gatunku S235. Wytworzone napoiny wykazały twardość 10-krotnie większą niż materiał podłoża.…”

Development and Research of Composite Coatings of Ti-B System, Sprayed by Microplasma Method

“…One of the most effective ways to create high quality products is to apply functional coatings of Ti-B system to friction units [3]. At the same time, an increase in the level of mechanical properties of coatings and an optimal product from the point of view of a complex of its characteristics is provided without a significant increase in the cost of the process [4]. Currently, the widespread use of titanium in various branches of mechanical engineering is due to the fact that it has such properties as corrosion resistance, fatigue fracture resistance, high specific strength, low modulus of elasticity, low density, cold resistance, and others.…”
