“…Each boriding process is founded upon the diffusion of boron atoms at high temperatures during a time period, resulting in either a monophase layer or a multiphase one [10,11]. This particular layer has multiple valuable properties, increased resistance to wear from abrasions [12], acids [13], oxidations [14], corrosions [15], erosions [16], and adhesions by decreasing friction [17,18]. Depending on the base material and other aspects, it also increases hardness to about 1000 or 2600 𝐻𝑉 and even higher [19,20].…”

Kinetic studies of boride layers focus on trying to accurately predict their thicknesses according to some variables using different approaches. In this paper, an approach that is reliant on a multilinear regression is investigated. In doing so, with an engineering perspective, temperature and time are used as the sole variables in predicting a boride layer thickness u. The approach uses experimental data from a boriding process performed on iron substrates of the XC38 steel. A comparison between the proposed linear model and a nonlinear one is seen afterward to scrutinize the results. That nonlinear approach is known as the diffusion model and is based on Fick’s second law, where it uses more variables than the linear approach to estimate its predictions. Ultimately, the comparison elucidated that the use of a linear regression-based model can be an accurate engineering tool to identify boride layer thicknesses, but without interpolating the results outside the scope of the studied interval.

“…This interface structure with the pinning effect is effective in preventing corrosion in liquid zinc. [20][21][22] However, the formation of such a structure depends on the formation and growth of corrosion products and is, therefore, limited by the state of the Fe-Zn compound during the corrosion process. Through the extensively studied ''Sandelin effect'', Si can affect the Fe-Zn reaction in the hot-dip galvanizing process.…”

The effect of Si on the corrosion of an Fe-B-Si alloy in liquid zinc was investigated. Corrosion tests of Fe-B-Si were conducted in a pure zinc bath (99.99 wt pct Zn). The results indicated that Si in a-Fe phase had a significant effect on the structure and evolution of corrosion interfaces in a directional Fe-B-Si alloy immersed in liquid zinc. Moreover, Si enrichment of the corroded interface induced changes in the mode of element diffusion, thereby affecting the Fe-Zn reaction and the quantity and volume of Fe-Zn compound. The Fe-Zn compound was occluded with the residual Fe 2 B closest to the corrosion interface, this structure could prevent direct contact between the liquid zinc and the alloy, and firm rooting of the compound at the interface. Therefore, Si in a-Fe phase had a significant effect on the corrosion resistance of Fe-B-Si alloy in liquid zinc. At a Si content of 0.318 wt pct, the densest composite corrosion product layer and highest corrosion resistance were obtained.
