The thermodynamic functions of iron boride and carbon-alloyed one Fe2(??) are considered. It is shown that iron boride Fe2B is quite thermodynamically stable within the temperature range from 1023 to 1223 K.

Abstract - The property such as microhardness of boridelayer formed on S45C iron was investigated. Boronizing was carried out in a solid medium consisting of nano size powders of 50% B4C as a donor, 45% SiC as a diluent, and 5% KBF4 as an activator treate... see more

In this paper we determine the crystallization temperature of a melt of the Fe-B system depending on the boron content and. The thermodynamic properties of the boron-bearing phases are studied. The investigation was performed for alloys with the boron con... see more

In this paper we study effect of carbon on structural and physical properties of FeB iron monoboride in Fe-B system alloys with carbon content of 0,05-0,90% (wt.) and boron content of 9,0-15,0% (wt.), the rest is iron. To determine the physical prope... see more

The paper presents the results of comparative analysis of the properties of coatings based on chromium, nickel and iron borides. The alloy obtained in the process of electron-beam surfacing of the powder mixture “amorphous boron – 10 wt.% chromium” has th... see more

The effects of substitution of Fe in the boron-rich Fe–B–C alloys, containing 10.0–14.0 % B; 0.1–1.2 % C; Fe – the remainder, 5.0 % Ti, Al, or Si (in wt. %) have been studied with optical microscopy, X-ray diffractometry, scanning electron microscopy... see more

In this work the study is performed for the specimens of Fe-B-C alloys with boron content of 0.005–7.0 wt. % and carbon content of 0.4–6.67 wt. %, the rest is iron. According to the findings of microstructure analysis, XRD and differential therm... see more

The boriding process is a thermochemical surface treatment which can be applied to many iron and non-ferrous materials and improves the properties of the material such as hardness, wear resistance. In the present study, the layer thickness values of the b... see more

Thermally-sprayed Fe-based coatings have shown their potential for use in wear applications due to their good tribological properties. In addition, these kinds of coatings have other advantages, e.g., cost efficiency and positive environmental aspects. In... see more
