The tribological tests are carried out to assess the effect of pin diameters on wear characteristics via changing contact stresses and sliding speeds to provide support for choosing friction pair sizes. The friction couple is set as CuZn pins for medium carbon steel (No. 1045 steel) rings. The differential wear rate and its calculation formula are defined to express the line wear rate or the wear...
This paper presents a study of the machining effect on tribological properties of ultra high molecular weight polyethylene (UHMWPE) in terms of coefficient of friction and wear factor under dry reciprocating sliding conditions. Machining parameters include cutting speed, feed rate and depth of cut. Polymeric structure of the semicrystalline polymer was characterized using differential scanning calorimetry...
The Cu-15 vol.% Cr in situ composite is a promising material for the electrical contacts in high current devices, since it has an excellent combination of mechanical strength and electrical/thermal conductivity. The electrotribological behavior of Cu-15 vol.% Cr was studied using a modified pin-on-disk tester with an electrical current applied across the sliding interface. The Cu-15 vol.% Cr pins...
The tribological behavior of Cu-20%Nb and Cu-15%Cr in situ composites was studied on a pin-on-disk tester. Composite pins were slid against a hardened AISI 52100 steel disk under dry ambient conditions. Comparison of coefficient of friction, wear rate and bulk temperature was made between the two composites in terms of effects of normal pressure and sliding speed. Microstructural changes in the composites...
