The Effect of Argon (AR) Gas Treatment on Energy Consumption Patterns and Carbon Steel Properties as a Result of Nitridation Using Plasma Nitriding

Introduction

Plasma nitridation or ion is one of the surface treatment methods carried out in moderate carbon steel, which comes from the raw material of the iron shaft as an engine component. This study aims to analyze the effect of argon gas treatment on energy consumption patterns and mechanical properties of medium carbon steel that is produced through the process of plasma nitridation. In order to obtain comprehensive data, experiments are carried out by varying the final treatment time, the ratio of a mixture of nitrogen gas (N2) and argon (AR), as well as pressure in the treatment of gas mixtures to find a combination that produces optimum results.

The use of plasma nitridation has been widely adopted in various industries, including the automotive and aerospace sectors, due to its ability to improve the mechanical properties of materials. However, the process also has its limitations, including high energy consumption and the need for precise control over the treatment conditions. In this study, we aim to investigate the effect of argon gas treatment on energy consumption patterns and mechanical properties of medium carbon steel produced through plasma nitridation.

Experimental Methodology

The experiments were conducted using a plasma nitridation system, which consisted of a vacuum chamber, a gas supply system, and a power supply unit. The medium carbon steel samples were prepared by cutting and grinding to a size of 10 mm x 10 mm x 5 mm. The samples were then cleaned and dried before being subjected to the plasma nitridation process.

The plasma nitridation process was carried out at a temperature of 500°C, with a gas mixture of nitrogen (N2) and argon (AR) being used. The ratio of N2 to AR was varied from 1:1 to 1:5, and the pressure was maintained at 100 mbar. The treatment time was also varied from 30 minutes to 120 minutes.

The energy consumption was measured using a power meter, which was connected to the power supply unit. The voltage and current were measured using a multimeter, and the power consumption was calculated using the formula: Power (W) = Voltage (V) x Current (A).

The mechanical properties of the treated samples were evaluated using a hardness tester and a wear tester. The hardness was measured using the Vickers hardness number (VHN), and the wear rate was measured using the wear rate equation: Wear rate (mm²/kg) = (Volume loss (mm³) / Weight loss (kg)) x 10^9.

Results and Discussion

The results of the experiments showed that the energy consumption pattern was affected by the treatment time, gas ratio, and pressure. The maximum power consumption was observed at a treatment time of 60 minutes, with a voltage of 800 V and a current of 10 A. The minimum power consumption was observed at a treatment time of 30 minutes, with a voltage of 700 V and a current of 5 A.

The mechanical properties of the treated samples were also evaluated, and the results showed that the hardness and wear resistance were improved with increasing treatment time. The maximum hardness achieved was 149 VHN, which is an increase of 104.1% compared to the initial material. The optimum wear rate was 35.23 x 10^-9 (mm²/kg), which is an increase of 18.4 times compared to the initial material.

Additional Analysis and Explanation

The plasma nitridation process using argon gas has several advantages, including increasing material hardness and improving wear resistance without increasing material weight. Argon gas functions as a protector and also helps in maintaining plasma stability during the nitridation process. In a mixture of nitridation gas, Argon also plays a role in controlling the reaction rate and nitrogen distribution on the surface of the steel, which contributes to an increase in mechanical properties.

Variable regulation, such as the ratio between nitrogen gas and argon, as well as the pressure used in the nitridation process, is very important to get optimum results. For example, changes in gas ratios can affect the density of nitrogen adsorbed on the surface of the steel, which in turn can affect the violence and wear resistance of the material.

Consistency in energy consumption patterns is also a key in optimizing the nitridation process. Using information from voltage testing can help in establishing more efficient and environmentally friendly parameters, thereby reducing energy costs and increasing productivity.

Conclusion

In conclusion, the effect of argon gas treatment on energy consumption patterns and carbon steel properties as a result of nitridation using plasma nitriding has been investigated. The results showed that the energy consumption pattern was affected by the treatment time, gas ratio, and pressure. The mechanical properties of the treated samples were also improved, with the maximum hardness achieved being 149 VHN and the optimum wear rate being 35.23 x 10^-9 (mm²/kg).

The findings of this study have significant implications for the industry, particularly in the production of engine components. The use of plasma nitridation with argon gas treatment can improve the mechanical properties of materials, reduce energy consumption, and increase productivity. Therefore, this study provides new insights into the optimization of plasma nitridation process, which can be applied in various industries.

Future Work

Future work can focus on optimizing the plasma nitridation process using argon gas treatment, including the development of new gas mixtures and treatment conditions. Additionally, the study can be extended to investigate the effect of plasma nitridation on other materials, such as titanium and aluminum alloys.

Frequently Asked Questions (FAQs) about the Effect of Argon (AR) Gas Treatment on Energy Consumption Patterns and Carbon Steel Properties as a Result of Nitridation Using Plasma Nitriding

Q: What is plasma nitridation, and how does it work?

A: Plasma nitridation is a surface treatment method that uses a plasma gas mixture to nitride the surface of materials, such as carbon steel. The process involves the creation of a plasma gas mixture, which is then used to nitride the surface of the material. The plasma gas mixture is typically composed of nitrogen and argon gases.
