<span lang="PT-BR">The work presented in this paper is to investigate the wear rate and wear mechanism of medium carbon steel with carbon contents of about 0,5 wt.% under the friction load with various contact surface temperatures. The wear test was performed by using the linear reciprocating ball-on-flat wear test machine. To develop the elevated temperature on the surface of the wear test specimen, the heater assembled into the wear test machine. The surface temperature of the wear specimen was set in the range of 30 ºC up to 250 ºC. The test was taken under 5000 cycles of friction loading with a maximum of the normal load of 25N. The experiment results show that the change in the contact surface temperature in the range of 30 ºC up to 250 ºC causes the wear rate to increase slightly. This is because the elevated temperature at the surface was not high enough to cause the hardness of the material to decrease significantly. The worn surface looks very thin scratches and slightly deformed layers, and the wear mechanism had identified as oxide wear.</span>

Purpose Fretting wear exists widely in the field of matching mechanical parts whereas previous research studies mostly focus on the point contact through a ball-plate tribometer. This paper aims to study the influence of wear debris on the fretting wear characteristics of the nitrided medium carbon steel under line contact condition at elevated temperature. Design/methodology/approach Fretting wear behavior of the nitrided medium carbon steel was experimentally investigated under line contact condition at elevated temperature and different normal loads without lubrication. Wear loss, worn surface and wear debris were studied to analyze the wear mechanism of nitrided steel. Findings The results showed that surface hardness of the medium carbon steel was notably improved because of the generation of a 230 µm nitrided case. Wear loss increased with the normal load, which was associated with the damage of a thin solid film formed by the wear debris, consisting of iron oxides and chromium oxide rather than only iron or iron oxides. The wear debris became partially amorphous and spherical because it was trapped within the contact interface and was ground, rolled, oxidized under line contact conditions. The spherical wear debris acted as a third body and formed a lubricating film between the contact faces. This lubricating film helped to stabilize the friction coefficient and reduced the wear rate, which further caused the acceleration of wear volume to gradually decrease. The wear mechanisms of the nitrided steel were oxidation wear, abrasive wear and fatigue spalling of the oxide layer. Originality/value The findings are helpful to understand the fretting wear behavior of the friction pair under line contact and enrich the fretting tribology theory.

Ti(C, N)-based cermet cutting tools were prepared by vacuum sintering and tested in dry machining of normalized medium carbon steel (AISI1045) at various combinations of cutting speed (Vc), feed rate (f), and depth of cut (ap). And the wear mechanism was investigated in detail using scanning electron microscopy (SEM) and electron-probe microanalysis (EPMA). Comparing to the cemented carbide YT15 and cermet TN20, the newly fabricated cermet tools exhibited better performance and higher wear resistance. For Ti(C, N)-based cermet tools, the wear mechanism was predominantly controlled by the flank wear under all cutting condition. It was found that the removal of the ceramic grain and abrasive wear were the main source of tools failure. In addition, adhesion and oxidation were also observed.

A rotavator is popularly used to reduce the amount of time and labour spent in field preparation. However, wear of rotavator blades is very high, especially in sandy soil, which significantly affects its working life. The wear test of selected rotavator blades were conducted in circular soil bin made up of different steel materials like medium carbon steel (M1), high carbon steel (M2) and boron steel (M3) to observe the effect of different steel materials on wear. The wear rate of M1 blade, M2 blade and M3 blade were 26.36, 24.96 and 24.05 mg/min, respectively. The boron steel blade was found having maximum hardness 41.8 Rc followed by high carbon steel blade (41.3 Rc) and medium carbon steel blade (39.9 Rc).

Maximum Contact

Wear behavior of AISI 1045 carbon steel has been studied on a washer-on-disk wear machine at bulk disks temperatures of 25°C and 200°C. An analytical approach to the temperature solutions was developed in terms of a parabolic temperature polynomial for the frictional contact area; the maximum contact temperature Tc is thus obtained by using several measured temperatures as boundary conditions. The tribological properties of carbon steel in sliding contact were studied to investigate the oxidational wear rate associated with the tribo-chemical reaction arising on the worn surface due to frictional heating. A theoretical approach to predict the oxidational wear rate of this carbon steel at 25°C and 200°C was also established.

One of ways to improve properties of materials without changing the product shape toobtain the desired engineering applications is heating and cooling under effect of controlledsequence of heat treatment. The main aim of this study was to investigate the effect ofheating and cooling on the surface roughness, microstructure and some selected propertiessuch as the hardness and impact strength of Medium Carbon Steel which treated at differenttypes of heat treatment processes. Heat treatment achieved in this work was respectively,heating, quenching and tempering. The specimens were heated to 850°C and left for 45minutes inside the furnace as a holding time at that temperature, then quenching process wasperformed in four types of quenching media (still air, cold water (2°C), oil and polymersolution), respectively. Thereafter, the samples were tempered at 200°C, 400°C, and 600°Cwith one hour as a soaking time for each temperature, then were all cooled by still air. Whenthe heat treatment process was completed, the surface roughness, hardness, impact strengthand microstructure tests were performed. The results showed a change and clearimprovement of surface roughness, mechanical properties and microstructure afterquenching was achieved, as well as the change that took place due to the increasingtoughness and ductility by reducing of brittleness of samples.
