The low-temperature tempering was held after boriding at a temperature of 200[degrees]C to remove the internal stresses.
The titanium alloy structure may be a factor intensifying the boriding process, although there is no consensus about the nature of its impact on the process of diffusion saturation of alloys with interstitial elements.
Therefore, the titanium alloy quenching was conducted at 900[degrees]C, namely at the temperature of boriding.
Similarly to structure, the texture can also affect the intensity of the titanium alloys boriding process.
Textured factor can be used to intensify boriding in the formation of hardened layers based either on titanium boride, or on a solid boron solution in titanium.
Surface hardening of the alloys' layers after boriding occurs due to formation of the borated layer with the well-developed boride and diffusion transitional zones.
where m and n are the resulting parameters of plotting x versus d in a potential form and d is the inner diameter of the cylinders, which represents the available boron potential for the boriding process.
This behavior suggests that the thickness of the FeB phase on the borided layers can be controlled by controlling the boron potential during the boriding treatment, which represents a great advantage because the FeB phase is considered as an undesirable subproduct of the boriding process [16].
The amount of atoms of boron mentioned above could be evaluated accurately because the samples were cylinders with a specific volume, which is called the "Volume of Control." Likewise, according to the reaction that occurs during the boriding process, the only source of boron available for the layers formation is [B.sub.4]C [7], which represents 5% wt.
This behavior highlights the importance of controlling the boron potential during the boriding process in order to control the mechanical properties of the achieved layers.
Likewise, the brittleness of the layer tended to increase as the boron potential was increased, which confirms the assumption that the mechanical properties are strongly related to the boron potential supplied during the boriding treatment.
