Sliding Wear Performance of Dry and Oil Impregnated Black-Fiber Palm Wood

The sliding wear of black-fiber palm wood was first investigated under dry conditions against smooth steel. Tests were carried out in two different configurations, i.e. pin on disc and ring on plate. In both cases, the transverse, in plane fiber orientation resulted in the highest values of friction coefficient and specific wear rate. The normal and parallel fiber orientations showed a better performance. In all cases, the coefficient of friction was rather high (average range between 0.4 to 0.7) whereas the specific wear rates varied between 10-6 to 10-5 mm3/Nm. The latter are comparable to those of short fiber reinforced thermoplastics. A following impregnation in various oils reduced the wear rates, and the friction coefficients went down to values between 0.1 and 0.3. The different efficiency of the various oils was discussed.

Conditions for Assuming a Conformal Contact to be Non-Conformal

A transition condition from a conformal contact to a non-conformal contact is studied. A cylinder-hole and the Hertz contacts are considered as a conformal and a non-conformal contact, respectively. First, the theory of the contact between a cylinder and a hole is revisited. The peak traction of it is compared with the Hertzian peak. In the case of the elastically similar materials’ contact, the non-conformal contact can be assumed until the angle of contact reaches almost 38% of the maximum possible angle of contact if the difference in the traction peaks of the conformal and non-conformal conatcts is set as 5%.

Tribo-Performance Analysis of Blast Furnace Slag Reinforced Polymer Composite: An Innovative Polymer Composite Research Work from Steel Sector

Blast furnace slag (BFSlag) is an industrial waste which is generated in huge quantities during iron making in steel industries. The present work attempts to utilize this solid waste BFSlag as the filler material in composite making with polymers like epoxy. The composites are characterized in regard to their physical and mechanical properties. An attempt has been made to improve the wear resistance of short glass fiber (SGF) reinforced epoxy composites by incorporation of micro-sized blast furnace slag (BFS) particles. A wealth of property data has been generated for a series of BFS filled epoxy/glass-epoxy. These material properties have been determined by conducting physical and mechanical tests under controlled laboratory conditions. Taguchi’s experimental design approach integrated with neural computation has been followed for the parametric appraisal and prediction of the wear processes. The morphology of worn-out surfaces is then examined by scanning electron microscopy (SEM) and possible  wear mechanisms are discussed. This study reveals that addition of blast furnace slag improves the fracture resistance of short glass-Epoxy composites significantly and thus makes them suitable for tribological applications.
