Abstract

This study used an experimental method, in the form of the heat treatment hardening 930⁰C with the variations in the cooling media of the coconut water, table salt water, mineral waterwater, coolant radiator, and dromus water and variations in temperatures of tempering 200⁰C, 420⁰C, and 600⁰C, the specimens were cylindrical in diameter 25 mm and 20 mm in length, this study aims to determine the optimum hardness value of S45C steel specimens due to the heat treatment process hardening-tempering. From the results of the study, there is the effect of hardening 930⁰C there is the most optimal hardness value found in coconut water cooling media with the hardness level of 53.5 HRC. Under the influence of tempering 200⁰C there is the optimum hardness value found from the influence of mineral water cooling media with the hardness level of 50.7 HRC, while the influence of tempering 420⁰C there is the most optimal hardness value from the influence of mineral water cooling media with the hardness level of 41.8 HRC, and for tempering effect 600⁰C there is the most optimal hardness value available from the influence of the coconut water cooling media with the hardness level of 35.93 HRC.

分析冷却剂对硬钢S45C对硬刺工艺的影响

本研究使用了一种实验方法，采用热处理硬化930⁰C的形式，冷却介质为椰子水、食盐水、矿泉水、冷却剂散热器和dromus水，回火温度为200⁰C、420⁰C和600⁰C，样品为圆柱形，直径为25毫米，长度为20毫米。本研究旨在确定S45C钢试样在热处理工艺调质后的最佳硬度值。从研究结果来看，930⁰C的硬化效果是最理想的硬度值，在椰子水冷却介质中发现，硬度水平为53.5 HRC。在回火200⁰C的影响下，矿泉水冷却介质的最佳硬度值为50.7 HRC，而在回火420⁰C的影响下，矿泉水冷却介质的最佳硬度值为41.8 HRC。为了达到600⁰C的回火效果，在椰子水冷却介质的影响下，硬度值为35.93 HRC是最理想的。
