Thermogravimetrical method studied the effect of alloying additions (on 0.01Γ·1.0 wt%) of neodymium and erbium on the oxidation kinetics of Zn0.5Al zinc alloy in the temperature range of 523β623 K. The values of the oxidation rate of the Zn0.5Al alloy and the alloy alloyed with neodymium and erbium, have been established in solid state. The behavior of ternary alloys with the participation of neodymium and erbium at the indicated temperatures somewhat differs from the oxidation of the binary Zn0.5Al alloy. For the eutectoid Zn0.5Al alloy, as compared with the alloys alloyed with neodymium and erbium, the minimum oxidation rate was noted. The addition of 0.5 and 1.0 % Nd and Er in the zinc alloy Zn0.5Al significantly increases its oxidizability. Alloy additions (on 0.01Γ·0.05 %) of neodymium and erbium slightly increase the oxidizability of the eutectoid zinc alloy Zn0.5Al. During the oxidation of the studied hard alloys, protective oxides pellicle are formed ZnO, Al2O3, Nd2O3, Er2O3, ZnAl2O4ΠΠ΅ΡΠΎΠ΄ΠΎΠΌ ΡΠ΅ΡΠΌΠΎΠ³ΡΠ°Π²ΠΈΠΌΠ΅ΡΡΠΈΠΈ ΠΈΠ·ΡΡΠ΅Π½ΠΎ Π²Π»ΠΈΡΠ½ΠΈΠ΅ Π»Π΅Π³ΠΈΡΡΡΡΠΈΡ

The article presents the results of a thermogravimetrical study of the effect of thallium alloying additives on the oxidation kinetics of the Zn22Al alloy. Established in the temperature range of 473β623 K the kinetic and energy parameters of the oxidation of alloys. The oxidation of alloys proceeds according to the hyperbolic mechanism and has the order of 10β4 kgβmβ2βsecβ1. Higher activation energies indicate that the oxidation of these alloy samples results in the formation of oxide films with good protective properties. Additives of thallium in amounts of 0.01β1.0 wt.% contribute to a decrease in the oxidizability of the Zn22Al alloy. The resulting products during the oxidation of the studied alloys consist of a mixture of oxides ZnO, ZnAl2O4, Al2O3, Tl2O3Π ΡΡΠ°ΡΡΠ΅ ΠΏΡΠΈΠ²Π΅Π΄Π΅Π½Ρ ΡΠ΅Π·ΡΠ»ΡΡΠ°ΡΡ ΡΠ΅ΡΠΌΠΎΠ³ΡΠ°Π²ΠΈΠΌΠ΅ΡΡΠΈΡΠ΅ΡΠΊΠΎΠ³ΠΎ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΡ Π²Π»ΠΈΡΠ½ΠΈΡ

The article presents the results of a potentiodynamic study of the anodic behavior of the Zn22Al alloy with erbium dopants in various corrosive media of HCl, NaCl and NaOH electrolytes. Erbium alloying additions corrosion rate in various corrosive environments. In this case, there is a shift in the potentials in amounts of 0.01Γ·1.0 wt.% somewhat increase the anode resistance of the Zn22Al alloy by reducing the of corrosion, pitting formation and repassivation of alloys to the region of positive values. The dynamics of changes in electrochemical potentials favorably affects the parameters of the corrosion resistance of alloys.

This article analyzes that the creation of mathematical models of chemical-technological
processes during the development of various alloys is supported to obtain promising new alloys in the
foundry industry. Mathematical models have been developed and analytically implemented using linear
algebra methods. Numerical values were determined and graphs of changes in the required parameters
were constructed. The development and analytical implementation of a mathematical model of the process
makes it possible to simplify practical research, and it is possible to predict the results of subsequent
experiments. This serves as the basis for the automation of chemical technological processes in the
production of non-ferrous metals and alloysΠ ΡΡΠ°ΡΡΠ΅ ΠΏΡΠΎΠ°Π½Π°Π»ΠΈΠ·ΠΈΡΠΎΠ²Π°Π½ΠΎ, ΡΡΠΎ ΡΠΎΠ·Π΄Π°Π½ΠΈΠ΅ ΠΌΠ°ΡΠ΅ΠΌΠ°ΡΠΈΡΠ΅ΡΠΊΠΈΡ

This paper examines the effect of heater power, speed of drying agent (air), adjustable slit
width and number of revolutions of drying drum on the drying efficiency of the device, the moisture
content of the rice pile coming out of the drum, and the chatness of rice in the rice pile. In addition,
showed the changes in the value of the heating power and the drying efficiency of the device. The
change of the adjustable slot size of the drying drum and the drying efficiency of the device consist
of determining the effect of the moisture content of the pile of rice coming out of the drum and the
effect of rice chatnash in the pile of rice. The experimental rice drying device in a stationary version
was prepared at the βAndijan experimental- testing plantβ JSC according to the design drawings developed by the Andijan Institute of Mechanical Engineering. Based on the results of theoretical
studies, a drying drum with a diameter of 880 mm and a length of 1800 mm was adopted as the main

The efficient operation of the technological equipment of machinery manufacturing enterprises
and heavy industry without distortion depends in many respects on the strength of their details. This
requires the study of the process of operation of the details, which are mainly rubbed with each other.
These methods are widely used in obtaining high-quality steel castings. The simplest method of processing
steel outside the oven is modification. Modified carbon steel is much more economical in properties
approaches to leached steel, while modified steel leached by saving and investigation approaches
leached steel with valuable and rare additives (Ni, Mo, Ti and other). Modification with alkaline and
alkaline-earth metals greatly increases the quality of steel. The quality of steel is positively influenced
by nitride-forming modifiersΠΡΡΠ΅ΠΊΡΠΈΠ²Π½Π°Ρ ΡΠ°Π±ΠΎΡΠ° ΡΠ΅Ρ
