The article presents results of M7C3 carbides stereological parameters measurement and wear tests of chromium cast irons. There are two types of material were compared: not inoculated chromium cast iron and the same material about 4% addition of titanium by weight. The samples for studies were taken from casting formed by pouring into ATD-Is tester mould. Then they were properly prepared for testing. Stereological analysis was conducted in ImageJ software, where the following parameters of carbides was measured: area, width, length, perimeter, and circularity. Wear test was executed using pin-on-disk method on Tribotester 3-POD. Results of research shown that Ti addition results in formation of TiC carbide, which is an underlay for crystallization of M7C3 carbides. The effect of this was the finer grain of M7C3 and the lower weight losses during abrasion.
