The Influence of Natural Frequency of the Experimental Set-up on the Friction Coefficient of Stainless Steel-304
Journal Title: Tribology in Industry - Year 2010, Vol 32, Issue 1
Abstract
The present paper investigates experimentally the effect of natural frequency of the experimental set-up on friction property of stainless steel-304. To do so, a pin-on-disc apparatus having facility of vibrating the test samples at different directions, amplitudes and frequencies was designed and fabricated. The natural frequency of the set-up was varied by adding dead loads of the setup from 0 kg to 50 kg. At each added load the friction coefficient has been measured. Results show that both the natural frequency and friction coefficient decrease with the increase of added loads. It has been also observed that the coefficient of friction increases with the increase of natural frequency of the experimental setup. The experimental results are also compared with those available in literature and simple physical explanations are provided.

Wear Behavior of PVD-Coatings
In cold forging high tribological loads often lead to premature tool failure. If the cause of failure is wear, an extension of tool life can be achieved by applying PVD coatings. According to the different load cases ap...
