PUB - Experimental investigations on the running-in behaviour of lead-free special brass alloys

 

A paper on "Experimental investigations on the running-in behaviour of lead-free special brass alloys" has been published in the journal Tribologie und Schmierungstechnik. It is an experimental comparison of the running-in behaviour of different lead-free special brass materials, which are compared with a lead-containing reference alloy.

In tribological systems with high loads, special brass alloys containing lead are preferably used because of their excellent wear properties. Axial piston pumps and motors are a good example of such systems. In order to be able to do without lead-containing materials in the future, alternative materials are being tested. The result of this development are three new lead-free special brass materials, which are presented in this paper. For these, the influence of the surface roughness (fine/coarse) and the manufacturing process (fine grinding + vibratory grinding/ lapping + vibratory grinding) on the running-in behaviour was investigated. The information on this is based on experience with the lead-containing reference material CuZn40Al2Mn2Si.
