AbstrakTeknik hardfacing merupakan pengerasan permukaan dengan menambahkan unsur atau lapisan terertentu agar sifat logam induk menjadi lebih keras. Pada blade buldozer umumnya dikeraskan dengan memberikan lapisan hasil pengelasan dengan elektroda khusus. Elektroda tersebut memiliki sifat kekerasan yang tinggi, sehingga blade pada buldozer tidak cepat aus. Dalam penelitian ini akan dilakukan dua kali proses quenching. Pertama dengan menggunakan air ketika selesai proses pengelasan. Kemudian dilanjutkan dengan pemanasan kembali dalam tungku kemudian dilanjutkan dengan proses quenching dengan dua media yang berbeda yaitu oli dan coolant. Dari hasil yang penelitian didapatkan hasil kesimpulan, media coolant merupakan media yang paling optimal dalam meningkatkan kekerasan dari hasil hardfacing. Nilai kekerasan yang didapatkan dari hasil pencelupan dengan media coolant adalah sebesar 299,73 HV Kata kunci: Hardfacing, HV 350, Quenching dan Kekerasan AbstractHardfacing technique is surface hardening by adding certain elements or layers so that the nature of the parent metal becomes harder. On the bulldozer blade is generally hardened by giving a layer of welding results with special electrodes. The electrode has high hardness properties, so the blade of the bulldozer does not wear out quickly. In this research two quenching processes will be carried out. First by using water when the welding process is complete. Then proceed with reheating in the furnace then proceed with the process of quenching with two different media namely oil and coolant. From the results of the study concluded, coolant media is the most optimal media in increasing the hardness of the results of hardfacing. The hardness value obtained from the dyeing with coolant media is 299.73 HV Keywords: Hardfacing, HV 350, Quenching and Hardness

Abstract This article introduces some of the general sources of heat treating problems with particular emphasis on problems caused by the actual heat treating process and the significant thermal and transformation stresses within a heat treated part. It addresses the design and material factors that cause a part to fail during heat treatment. The article discusses the problems associated with heating and furnaces, quenching media, quenching stresses, hardenability, tempering, carburizing, carbonitriding, and nitriding as well as potential stainless steel problems and problems associated with nonferrous heat treatments. The processes involved in cold working of certain ferrous and nonferrous alloys are also covered.
