This article presents the possibility of using the replication method to measure selected parameters of the surface geometry. The results of the tests obtained while measuring the replica and surface of the tested object are presented. The obtained results indicate the suitability of using RepliSet F5 to measure the roughness parameters (Ra and Rz), microgeometry tool, and grinding wheel. It has been...
In this study, locally available waste coconut (Cocos nucifera) shells (CSs) were investigated as possible replacement for asbestos-based brake pads. The CS-based brake pad was tested for its physicomechanical properties and compared with a commercial brake pad used as control sample. The results showed that (a) an improved interfacial bonding between the CS particles and the binder as the grain size...
The present paper studies and analyzes the low-pressure vacuum carburizing of Pyrowear 53 steel. The carburizing was performed at 921°C. The results after the completion of the treatment process are presented, i.e. microstructure of the surface layer and hardness. The results confirm that carburizing can be effectively used in hardening of the steel.
