چکیده انگلیسی
A plasma electrolytic borocarburizing process (PEB/C) in borax electrolyte with glycerin additive was employed to fabricate a hardening layer on Q235 low-carbon steel. Optical emission spectroscopy (OES) was utilized to investigate the spectroscopy characteristics of plasma discharge around the steel during PEB/C process. Some plasma parameters were calculated in terms of OES. The electron temperature and electron concentration in plasma discharge zone is about 3000-12,000Â K and 2Â ÃÂ 1022Â mâ3-1.4Â ÃÂ 1023Â mâ3. The atomic ionization degrees of iron, carbon and boron are 10â16-10â3, and 10â23-10â6, 10â19-10â4, respectively, which depend on discharge time. The surface morphology and cross-sectional microstructure of PEB/C hardening layer were observed, and the electrolyte decomposition and plasma discharge behaviors were discussed.
