Friction And Wear Tests

Friction and wear tests of stainless steel rubbing against copper-impregnated metalized carbon with electric current were carried on the pin-on-disc tester. The result indicates that arc discharge occurs in the process of experiments, and the intensity of arc discharge of interface increases with increasing of electric current and sliding velocity. As increasing of the arc discharge intensity, friction coefficient shows a tendency of slightly increase. While the rate of copper-impregnated metalized carbon material increase significantly with the increase of arc discharge intensity. Through observing the worn surface morphology of pin samples, it is found that the abrasive wear is dominant at small arc discharge due to worn particles and arc ablation craters, but arc erosion and oxidation wear are the main wear mechanisms in condition of large arc discharge due to arc discharge and its producing high temperature. The materials transfer of contact couple occurs in the process of friction and wear.

A serials of experiments were carried on the pin-on-disc friction and wear tester. The friction and wear behaviors of on four materials couple with electric current were studied on in different conditions. The result indicates that properties of materials couple have a significant influence on the test results. The friction coefficient is the highest in process of the copper-impregnated metallized carbon rubbing against pure copper couple, and its wear volume of carbon strip material is also the largest. However, the friction and wear volume of copper-impregnated metallized carbon/stainless steel and pure carbon/pure copper couples are lower. Therefore, both friction couples are appropriate for pantograph strip/contact wire couple.

ABSTRACTImplantation of Ti and C into stainless steel discs of Types 304, 15–5 PH, Nitronic 60 and 440C has previously been reported to reduce wear depths by up to ∼ 85% and friction by ∼ 50% in unlubricated pin-on-disc tests. Our earlier studies relating microstructure to friction and wear results in Type 304 are first summarized; these indicate that the improvements in the surface mechanical properties are due to an amorphous surface layer, similar to the amorphous layer observed in pure Fe implanted with Ti and C. We have now examined the other three implanted steels and found similar amorphous layers. These results strongly suggest that the amorphous surface alloy is responsible for reduced friction and wear in all the steels.

Present work aimed at investigating the friction and wear of martensitic stainless steel of grade 410. This steel is used in nuclear industry for various moving components due to its high strength and moderate corrosion resistance. Properties of this material depend upon the heat treatment to which subjected to. The wear tests by sliding were performed on a pin on disk apparatus whose pin is in normalized and tempered condition. The counter face disc was machined from EN24 steel of high hardness in nature. The AISI 410 stainless steel wear rates were evaluated using Pin-on Disc Tribometer at various load and sliding speed. The worn pins were investigated by using scanning electron microscopy and surface profilometer.

Resistance To Wear

Dimples with various pitches and densities were produced using laser surface texturing (LST) to improve the friction and wear behavior of graphite cast iron. The objective of this study is to investigate the effectiveness of dimples on the friction and wear behavior of an internal combustion engine (ICE) cylinder. The specimens with a dimple pitch of 150 μm and a dimple density of 13% exhibited the lowest friction coefficient among the specimens, while the specimens with a dimple pitch of 200 μm and a density of 7% exhibited the highest resistance to wear.
