Abstract

Generally, metals are easy to wear, so material modification is needed to increase hardness to increase the material's resistance to wear and tear. One way is to do a hard chrome plating process using the electroplating method and then continue the heat treatment process. This research was conducted to observe changes in the mechanical properties and microstructure of S45C steel that underwent hard chrome and heat treatment processes. This research was conducted by inserting S45C steel as a cathode into hard chrome liquid and using lead (Pb) as the anode. A positive (+) current powers the anode, the cathode has a negative current (-), the voltage used is 12 V with a duration of 60 minutes. After the cathode was coated with hard chrome, a hardness test was carried out, then continued with the heat treatment process using a temperature of 850°C for 30 minutes. The hardness test results show an increase in the hardness of S45C steel that has been coated with hard chrome, with a hardness value of S45C steel 202.70 VHN, S45C hard chrome steel 998.63 VHN. The highest hardness value is S45C steel coated with hard chrome 998.63 VHN, increasing 392.7%. Then the heat treatment process experienced a decrease in the hardness value, 528.90 VHN, with a percentage of 88.81%. The results of the microstructure observation showed that the hard chrome layer that had been heated treated showed even cracks in the hard chrome layer.

Abstract

The combination of Quenching and Shot peening (SP) heat treatment is rarely carried out, especially the use of this treatment can improve the mechanical properties of medium carbon steel (S45C). This study aims to analyze the microstructure and hardness of S45C steel with the combined effect of Quenching heat treatment with shot peening with variations in compressor air pressure. Commercial S45C steel is quenched with a heating temperature of 910oC and held for 15 minutes. In comparison, the SP process is carried out after the quenching process with variations in air pressure, namely 4, 5, 6, and 7 bar. Analysis of the combined results of Quenching and SP processes using hardness and microstructure. The investigation analysis results obtained specimens with the highest surface hardness in the quenching and SP treatment of 899.44 HV. The impact of SP on the surface up to a distance of 120 m from the surface. The highest hardness was in the Quenching and SP treatment with a pressure of 7 bar. The results of this study are used as parameter contributions in the area of surface treatment and heat treatment of carbon steel to be developed in the automotive industry.

Abstract

This study used an experimental research method, which is a research method that aims to understand the causal process by treatment and conducting controlled testing on a sample of research subjects. This research uses quantitative methods by taking research data in the form of numbers. The material used in this study is the gear sprocket. A gear sprocket is a motor component that transmits power from the engine to the rear wheels so that the motor can run optimally. The sprocket gear was heat treated at 850 ℃ with a holding time of 20 minutes. The variations of quenching media are mineral water, dromus coolant, and SAE 40 oil. Hardness and microstructure tests were carried out for each specimen to determine the effect of different cooling media on the quenching process. The results of this study indicate the highest specimen hardness value was obtained at 301 HV by immersion in mineral water media. The lowest hardness was obtained at 207 HV with SAE 40 oil media immersion. Meanwhile, the non-treatment material hardness is 150 HV. In this case, there was an increase in the highest hardness of about two times compared to non-treated specimens. Observation of the microstructure shows that the grain size of the mineral water quenching specimens looks smaller than that of the non-treatment models. This phenomenon supports the idea that quenching can increase the surface hardness of the gear sprocket.
