... – on chloride concentration, chloride diffusion coefficient (K), surface chloride concentration (C_s), and the pore structure of HFRC . The results demonstrated that incorporating 1.5% BF significantly reduced the chloride concentration compared with 0.25% bF. Following a power...

.... 22 , 23 In highly alloyed steels, the presence of alloying elements reduces the boron diffusion rate, thereby inhibiting the progression of diffusion. Consequently, this phenomenon leads to a sawtooth-like structure in low alloy steels, whereas a flatter structure is noted in high alloy steels. 24...

.... This clarifies the influence of the mechanical load in governing the occurrence of diffusion during corrosion. The phase changes experienced by a material are used to characterize the movement of the corrosion boundary, and the concentration of material points is used to characterize the degree and extent...

...Isuf Tredhaku; Sefer Avdiaj Determination of the diffusion constant for specific cases can be achieved in different ways. One of them is by outgassing some gas in high vacuum from a solid body. In this paper, the diffusion constant of helium from ultralow expansion (ULE) glass is determined...
