Abstract

It refers to the use of a graphical technique in combination with the experimentation standardized by ASTM G99 to identify a parameter that characterizes and quantifies the wear behavior of a steel thermally and/or chemically variously treated, such as those used to build tools for working hard materials or moulds for the powder metallurgy. In particular, the experimental procedure adopted, the data acquisition modes of the tests, the processing mode and interpretation of these latter are described. Finally, the precision with which the wear parameter is evaluated by the graphical technique and the possibility to distinguish - with only one test - the wear behavior of the treated surface layer from that of the base metal are pointed out. The material used for the creation of the various specimens' samples is the sintered Vanadis 4 Extra. Each sample was subjected preliminarily to one or two of the following treatments: quenching, cryogenization, nitrogenization and coating with the PVD coating technique.
