Analysis of wear for a base Steel 5% Cr, applying 392 N of load and variable speed of 0.18 m/s, 0.36 m/s and 0.54 m/s, using the T05 Block-on-ring wear tester machine

Abstract

In the present study, an experimental analysis of the friction forces, speeds and friction coefficients that influence the size of the wear track in a steel exposed to mechanical contact was carried out, for this, steel blocks with an alloying element of. 5% Cr base and D2 steel standard ring, representing the Block-on-Disk method, according to the ASTM D2714 standard were used. The test parameters were: 392N load, for 800 seconds, with variable speeds of 0.18 m/sec, 0.36 m/sec and 0.54 m/sec; the test is performed in a dry environment using the T-05 Block-on-Ring wear tester machine. This analysis contributes to the technological development of a material that has a lower coefficient of friction and therefore improves its mechanical properties for systems exposed to this principle, such as the wheels of traveling cranes or railway trains, diesel machinery transport systems and various services, etc.
