The Influence of Carbon, Carbon, and Boron on the Formation …

In [7], it has been shown that the diffusion front of the boride layer has a sawtooth
form, while that of the RE-borosulfide layer is flat. Another from the BL layer, the
RBSL layer is thin, entire, and plane. The results of FeS, Fe 2 B, and FeB phases on the
substrates were obtained by Auger electron spectroscopy analysis. The wear resistance test reflected that within a certain range, the abrasion resistance of the RBSL
layer is finer than that of the BL layer, precisely under the high-load circumstance.
The corrosion antiperistalsis test using the weight loss method has proven that the
corrosion resistance of the RBSL layer is finer but declines faster with time extension
than that of the BL layer.

Diffusion saturation is carried out on parts made of steel (1.2% carbon). The complex
method consists of several stages (Fig. 1). The main stages are chemical deposition
and diffusion saturation on the surfaces of the machine parts [8–10].
First, machining of the surfaces of parts is carried out to a size that takes into
account the surface build-up during chemical deposition and diffusion saturation.
Mechanical cleaning, degreasing, and then decapitating are required, which significantly activate the surface prior to deposition. Decapitation is carried out in acids,
followed by washing. During the chemical deposition, care should be taken to ensure
that suspended specimens do not come into contact with each other and that the
medium is maintained at a pH of 9–10 (Fig. 2).
