Abstract

The material, characterized by a porosity of 30-60 %, comprises chromium nitride and seminitride at a weight ratio of 1:0.01-0.8 and 17-25 wt.% of nitrogen. The method provides for nitrification of a chromium-containing component in powder form in nitrogen at a pressure of 1-16 MPa, by means of layer-by-layer burning of that component to obtain chromium seminitride, and maintaining it at a temperature of 1190-800 °C, wherein a chromium-containing component is used with a chromium content of 65.0-99.5 % by weight.

"A good piece of material on the basis of no more ^• what’s right for the good of you ^"

The wide range of technology is available for a high of 5 available materials for alloying steels, and moreover, there is an aggregated aggregate.

PREFERRED EMBODIMENTS Alloying Asian materials on a simple base must be available for large, non-obsolete vehicles. This means that the SIECS system is secured by it, it quickly ceases without a significant reduction in its temperature, it eliminates the danger of dying elements, and the

The available material on the USC metal is available and the iron and nitrous metals are W-UP group Per-5, which is available in a separate way. The method of making it is included.

In this way, metal smelting of iron and the formation of nitrous Ε metal are ensured by the W-UP group sys- tem of the element system. -

The described method reveals the best way to save energy, the duration of the process, not to use the available products. It is also slowing down due to the low pressure, which reduces the small increase in the rate of increase in the rate of increase in the rate of the increase in the rate of the increase in the rate of the increase in the rate of the increase in the rate of the increase in the rate of the increase in the rate of the increase in the rate of the increase in the rate of increase in the rate of increase in the rate of the increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the degree of increase in the degree of increase in the degree of increase in the degree of increase in the rate of the increase are not observed in the case of the increase of the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of increase in the rate of the increase in the degree of increase in the rate of the increase in the degree of increase are the degree of the increase Keeping nitrogen in place will result in a significant degree of dispersion of the original source. This follows from apertured ayurums of the product range, the last one contains nitride and is free from a mass of 1, 0.8, at a rate of 1: 0.8, . The low temperature of the unit reduces the temperature of the liquid, due to the considerable decrease in temperature If you remove it, it emits a malfunctioning device that has a low output and an inadequate separation of impaired phases, which could result in a malfunctioning condition. Due to this method, sizes (50-100 mm) are limited because of the resulting material due to the influence of the thickness of the sample.

nitrogen and steel, as a result of which there is a decrease in the operating life of the plasma, and a decrease in the angle of gas and nitrogen. It is advisable that the material, according to the invention, contains aluminum nitride in the amount of 0.4-36 wt. .

Due to his eating habits, he was able to remove the waste of food, save it from waste and, therefore, have a high amount of nitrogen in the material. When consumed, the liquid steel of the nitrogen-sintered sintered material on the base aluminum nitride is decomposed with the nitrogen excreted, and the supplied aluminum is removed and removed

The proposed method is characterized by low energy and workloads, as the process of starting the process takes 0.2 to 1 hour to wait for it to be received.

Such material is not possible to use at the expense of alloying mining. 0 When using aluminum, the optimal conditions of the burning process are ensured. The identified dispersion of the component that provides access to the most advantageous components is that the process is inactive. Particle sizes less than 0.01 m / 5 lead to a large amount of acid and carbon dioxide.

It is suggested that you turn on the nitrogen in the case of an armored appliance. This ensures that the material is obtained according to the invention with the specified dimensions.

CONDITIONS OF CONDITIONS FOR NITROGEN AND COOLING COMPONENTS WERE EXPRESSED.

The use of a refrigerant discharger accommodates a surplus of nitrogen, which supports the supply of Ι-Ι6 аPa. With πз-5. With the help of the second generation, the local local initiating process of the immediate burning was suppressed. After that, filtering through an exhausted component, due to a reduction in pressure and a negative voltage, and after the operation starts

- b - the intensive interaction between the burning and the latter, in the form of a floor, the unit of the furnace. The appliance is not heated until it reaches Ι300-2Ι00 ° C due to the release of heat from the nitriding station. The processing of nitrous oxide is not a matter of any kind. The prerequisite for this stage of the Asian initiation is maintenance of the Ι-Ι b Μ Pa. A pressure below I ΜPa slows down the speed of the recovery and heat release. If above 16 ΜPa ^, an increase in nitrogen content does not occur in the material, but due to the technical failure of the process, the result is a loss of process. Increased pressure of the station to ensure the rapid expansion of the station; The range of the external phase and the low temperature (Ι300-2Ι00 ° C) is insignificant;

It should be noted that the process of burning also affects the presence of a commercially available component and its distribution.

A convenient type of cooling device can be obtained by any means: shredding, electrolysis, spraying, settling, condensation from a waste gas.

It is proposed to use omens containing a compound with a content of 65-99.5 wt. .

The use of a coke oven to produce a material that is practical from one phase-nitrate of coke - with a maximum content of nitrogen (21, 7 wt ^). The waste of such material, as a result of alloying, has become significantly reduced, without a significant reduction in its temperature.

Aluminum is a non-ferrous metal; it can be treated with nitrous oxide; The incidence of the inconvenience of the cry does not deteriorate.

With an increase in the aluminum content, the ISDΧΟ material is more than 36 wt. There is no complete waste of aluminum 5 Ε nitride and no burning. Flame-free aluminum is released when it is consumed, it reduces the risk of impairment of activity for the non-operating environment. 0 Received feedback from the user is subject to the same conditions.

(giving Ι-Ιб ΜПа, excess of nitrogen), by the way, changes in the phase of the system are not observed. The winning time is very short and is 0.005-5 seconds long. A change in the temperature of the nitrous oxide and nitride of the oxygen starts at 5 ° C, at a temperature of 90 ° С, but there is no connection to the device. At this stage of the nitrogen supply, you should keep the excess nitrogen in mind, by intensifying the consumption of nitrogen, by intensifying the consumption of nitrous oxide.

At the same time, the nitride of chrome is at the expense of the low density of the phase, at the temperature of 1190-5 80 _. 0 ° C occurs during the process of burning. Skeneniya- is used for convenient mechanism, such as nanotruids, and this temperature is not working. At temperatures below 800 ° C, the process of processing is in progress. - 8 - the material is rejected. As a result, the process is achieved with the goal of a mass ratio of nitrate and polunitide of 1: 0.01–0.8 times the oil consumption. , there are practical

5 other possible interconnections. It is available for 30–60 years, and is limited to 5–50 PS compressions, with an additional weight of 3.5 kg / m ³ . This complex Syss makes it indispensable, with the highest amount of alloying mining and production ceasing.

10 BEST MODE FOR CARRYING OUT THE INVENTION

The resulting polynitruid of the chill is eliminated by excess nitrogen with a pressure of 12 Μ Pa а for 5 seconds. At a temperature of ΙΙ90 ° ^{C, the} polynitride of the chrome begins to interact with nitrogen, reducing its content of Ε rean-
