Iron-phosphorus alloys coloured kitchen knives consist of iron phosphides and phosphorus in solid solution iron. In industry, a well-known product is ferrophos (Technical iron phosphide) is used as a deoxidizer in the steel industry. In a rather significant quantities it is formed and the electrothermal production of yellow phosphorus. But the use of ferrophosphorus as a deoxidizer coloured kitchen knives met considerable difficulties because of the high content of silicon and other impurities, but also of the inconstancy of composition. Therefore coloured kitchen knives proposed a number of its processing technology for various phosphates, coloured kitchen knives among which there are electrochemical methods [1-3].
Its physical and chemical properties ferrophos refers to a group of substances, defined the concept of "hard metals". coloured kitchen knives This substance metallic coloured kitchen knives nature, with high hardness, high melting point, high heat - and conductivity as well as good resistance to chemical attack [2,7].
In order to study the electrochemical behavior of phosphides were used alloys obtained by ampoule made of extremely pure metal powders and red phosphorus by using self-propagating high-temperature synthesis. Metallfosfornye investigated alloys coloured kitchen knives (S = 5 mm 2) were carried out in the form of a disk electrode and inserted into the PVC pipe. The use of this isolation eliminates input insulating cements, which can cause contamination of the electrolyte. Current was fed to the anode through soldered to a copper wire ferrophos disk. Anode before each experiment carefully sanded increasing numbers purified mixture Eshka, coloured kitchen knives pickled with 5% sulfuric acid solution, washed several times with the distillate.
Current-voltage measurements were carried coloured kitchen knives out at 25 C in the potentiodynamic mode potentiostat PI 50-1.1. Potential sweep rate was 0.01 mV / s. Electrolyzer in potentsioinamicheskih studies served as a three-electrode glass cell. The auxiliary electrode is a platinum plate was used with surface 0,4 10 -3 m 2. Reference electrode
