STUDY ON VANADIUM CARBIDE COATING FORMATION ON AISI L2 STEEL BY THERMO-REACTIVE DEPOSITION TECHNIQUE
Abstract: The possibility of vanadium carbide coating formation on AISI L2 steel was studied in molten salt bath containing 33 wt% NaCl- 67 wt% CaCl2. In this research, the effects of time, temperature and bath composition on growing layer thickness were studied. The vanadium carbide coating treatment was performed in the NaCl-CaCl2 bath at 1173, 1273 and 1373 K temperatures for 3, 6, 9 hours a...
Carbide coatings, due to their excellent anti-wear properties, are used to extend the life of molds exposed to abrasion forces. Various processes have been applied to produce carbide coatings. Thermo-reaction diffusion (TRD) using a molten salt bath could be considered as an economical method compared to other coating processes. In this study carbide-composite coatings using molten salt baths c...
Studies were designed to examine whether the thin ascending limb of Henle (tALH) decreases its luminal solute concentration by an active or a passive transport process. In all experiments isolated segments of rabbit tALH were perfused in vitro. When tubules were perfused with solutions identical to the bath, active transport of NaCl was excluded by the following: (a) osmolality of the collected...
We introduce the additives effect in molten salts such as commercially pure KNO3 and polluted KNO3. The results showed that case of commercial purity KNO3, only KOH improved compressive stress (CS) ion-exchanged glasses up to ∼50 MPa, others did not make CS improvement. Rather than was diminished by additive contamination. In contaminated K3PO4, K2CO3, K2SO4 successfully removed impurities, Na+...
