Copper-based alloys with the addition of Al present excellent properties and can be considered a proper choice for applications as contact materials based on their good strength and fret resistance. Cu-Al alloys are used in different systems parts as bearings, gears and worm gears. The intention is to replace steel materials with new copper-based materials for parts that work in a possible explosive environment to reduce the possibility of spark appearance. Copper-berilyum alloys are known as non-sparking alloys and are used in different tools obtaining for environments with possible explosive gaseous. Results from the obtaining and analysis of a new alloy based on CuAlBe are given. The material was melted in a vacuum induction furnace from CuBe master alloy and high purity aluminium and cast into a metallic die. The alloys obtained were analyzed using EDS – energy dispersive spectroscopy for chemical composition, OM-optical and SEM-electronic microscopy for the microstructure, and the electro-corrosion resistance was tested using linear Tafel diagram and cyclic potentiometry.

Railway buffers during the operation are staying in almost permanent contact with each other, creating friction node in the point of contact

of two railway buffer heads. In consequence of overcoming track curves, turnouts and unevenness of track, the railway buffer heads moves

relative to each other causing friction, which results in its wear. When the wear is excessive, it might be a reason to withdrawn vehicle

from service, it causes flattening of buffer head, and in consequence its abnormal cooperation. To avoid this phenomenon the buffer heads

should be covered with graphitized grease, but this method has many disadvantages. Accordingly, it was found that it would be beneficial

to cover the buffer head with bronze using laser cladding. In this article the metallographic and mechanical analysis of the newly created

top layer of railway buffer head are presented. In article the results from tribological tests conducted on Amsler test bench are also

presented. Based on test results described in article concluded that the layer of bronze coat on working surface of railway buffer head can

be beneficial from operational point of view.
