Effect of Heat Treatment Hardening on the Dry Sliding Wear Behaviour of Mild Steel

Abstract

Abstract:Mild steel offers a variety of properties for various applications at lower costs giving the alloy a large application base in industry. However, the increasing complexity and severity of service environments has shifted the focus of many industries to structure modification techniques, like heat treatment, to improve material properties and performance. The focus of this paper was to therefore investigate the effect of heat treatment induced hardness on the sliding wear behaviour of mild steel. The results showed that resistance to dry sliding wear increased with increasing hardness of the mild steel samples. Both abrasive and adhesive wear mechanisms were observed to occur on the samples, however abrasive wear was predominant.

Influence of aging treatment on mechanical properties and wear resistance of medium manganese steel reinforced with Ti(C,N) particles

“…The hardness and impact energy are the best indicators for evaluating the material properties that affect the service life and wear efficiency of wear-resistant products [40][41][42]. Figure 4 shows the hardness and impact energy of medium manganese steel after different heat treatment.…”

Perlakuan Panas Bertingkat Sebagai Upaya Meningkatkan Kekuatan Mekanik Baja Karbon Rendah

“…Pengerasan permukaan logam dengan proses perlakuan panas juga terbukti menurunkan tingkat gesekan dan keausan, hal ini disebabkan oleh perubahan mikrostruktur sebagai akibat dari transformasi fasa, peningkatan energi permukaan dan tegangan sisa internal. Perlakuan panas yang mendinginkan logam dengan cepat sebagian besar menghasilkan transformasi martensit (Lebudi, Phiri, Leso, & Oladijo, 2020). Sedangkan pada proses tempering, dikarenakan proses pendinginan yang lambat menyebabkan karbon yang terbentuk kembali terlepas dan tidak terbentuk martensit, sehingga kekerasan dan keausannya menurun.…”
