Improvement of the Physical and Mechanical Properties of Aluminum A356 Applied to the Fishing Boat Propeller Combined with Titanium Carbide (TIC) 0.15%, 0.17% and 0.19% Using Cooling Slope with a Slope of 60°

Introduction

Aluminum Matrix Composites (AMCs) have gained significant attention in recent years due to their superior mechanical properties compared to traditional aluminum alloys. The addition of reinforcement materials such as Titanium Carbide (TIC) has been shown to enhance the physical and mechanical properties of aluminum alloys. In this study, we aim to investigate the effect of variations in TIC composition (0.15%, 0.17%, and 0.19%) on the physical and mechanical properties of aluminum A356 applied to fishing boat propellers using the Cooling Slope technique.

Background

Aluminum A356 is a widely used aluminum alloy in the technical field due to its excellent castability and mechanical properties. However, its performance can be further improved by adding reinforcement materials such as TIC. TIC is a hard and wear-resistant material that can enhance the mechanical properties of aluminum alloys. The addition of TIC has been shown to improve the hardness, wear resistance, and impact resistance of aluminum alloys.

Methodology

In this study, we used the gravitational casting method to produce specimens of aluminum A356 with varying TIC compositions (0.15%, 0.17%, and 0.19%). The specimens were cast using a Cooling Slope with a 60° pouring angle, 300 mm path length, and a constant pouring temperature at 680°C. The mechanical properties of the specimens were evaluated using the Pin-On-Disk method with a variation of 90 rpm, 180 rpm, and 210 rpm. The microstructural analysis was also conducted to examine the effect of TIC addition on the α-al microstructure.

Results

The results of this study showed that the variation of TIC composition had a significant effect on the mechanical properties of aluminum A356. The highest hardness value was achieved in a variation of 0.19% with a value of 58.30 bhn at the bottom of the specimen. Meanwhile, the highest impact value was obtained at a variation of 0.15% at the top of the specimen, which reached 12.78 J/mm². The Ultimate Tensile Strength (UTS) value was also found to be highest in the 0.19% variation, which is 113.24 MPa.

Discussion

The addition of TIC to aluminum A356 has proven effective in improving the performance of the material used in fishing boat propellers. Physical and mechanical properties such as hardness, impact resistance, and wear resistance experienced a significant increase, thus making propellers more durable and effective in their use. The results of this study also indicate that the addition of TIC contributes to the refinement and composition of the α-al microstructure.

Additional Analysis and Explanation

The addition of titanium carbide (TIC) to aluminum A356 has proven effective in improving the performance of the material used in fishing boat propellers. Physical and mechanical properties such as hardness, impact resistance, and wear resistance experienced a significant increase, thus making propellers more durable and effective in their use.

  • Hardness: With the addition of TIC, hardness in the material increases. This is important for propeller applications that must withstand friction and pressure when operating in water. Increased hardness makes propellers more resistant to damage.

  • Impact resistance: High impact value indicates that propellers are not only strong in static conditions but can also withstand dynamic loads when operating. This is very important for fishing boat propellers who often face diverse sea conditions.

  • Reduction of wear rates: This research also indicates that by using the Pin-On-Disk method, the rate of wear can be reduced. This means that the resulting propeller is more durable and requires less maintenance, which is an added value for fishermen who depend on this tool.

  • Microstructure: Microstructure that is smoother and tight, as a result of the addition of TIC and the use of Cooling Slope, also contributes to improving mechanical properties. A good microstructure provides greater resistance to deformation and broken, which is very important in applications at sea.

Conclusion

Overall, this study shows that the combination of aluminum A356 and titanium carbide (TIC) using the cooling slope technique not only improves the quality of propellers but also provides a more effective and efficient solution for fishermen. It is hoped that the results of this study can be utilized by small and medium industries (IKM) such as Citra Widi Mandiri MSMEs to produce higher quality propellers.

Recommendations

Based on the results of this study, the following recommendations are made:

  • Further research is needed to investigate the effect of TIC composition on the mechanical properties of aluminum A356.
  • The use of Cooling Slope technique should be explored further to improve the quality of propellers.
  • The results of this study should be utilized by small and medium industries (IKM) to produce higher quality propellers.

Limitations

This study has several limitations, including:

  • The use of a limited number of TIC compositions (0.15%, 0.17%, and 0.19%).
  • The use of a single type of aluminum alloy (A356).
  • The use of a limited number of mechanical properties (hardness, impact resistance, and wear resistance).

Future Research Directions

Future research directions include:

  • Investigating the effect of TIC composition on the mechanical properties of aluminum A356.
  • Exploring the use of other reinforcement materials such as silicon carbide (SiC) and alumina (Al2O3).
