TLDR
In this article, the effect of the purity level of natural barytes in brake pads formulation to enhance the tribological performance by altering tribofilms and preventing friction undulations was investigated.Abstract:
This paper aims to deal with the effect of natural barytes purity levels on the tribological performance of brake pads.,In this study, brake pads were developed by varying three different natural barytes without varying other ingredients. The brake pads were developed as per the standard industrial practice. The physical, mechanical and thermal properties of the developed brake pads were tested as per the industrial standards. The tribological properties were analyzed using a full-scale inertia brake dynamometer. Worn surface analysis was done using scanning electron microscope coupled with elemental mapping.,The experimental results indicate that the brake pads filled with natural barytes 95% purity had good physical, chemical and mechanical properties with stable friction and less wear rate due to reduced impurity level preventing frictional undulations.,This paper explains the effect of the purity level of natural barytes in brake pads formulation to enhance the tribological performance by altering tribofilms and preventing friction undulations.read more

Effects of water films and sliding speed on the frictional behavior of truck disc brake materials
Peter J. Blau,J.C. McLaughlin +1 more
TL;DR: In this article, the authors investigated the frictional behavior of commercial truck brake pad materials sliding on gray cast iron simulated brake discs in the presence of water films and found that the reduction of friction with increasing speed was principally due to hydrodynamic effects, although the water spray also reduced frictional heating and changed the nature of the transfer film formation on the cast iron contact surface.
