New methods of diffusion metallization AISI W1-7 steel have been developed. The paper proposes a comparative analysis the properties and characteristics after three chemical heat treatment: nitriding, nitrogen titration by physical deposition from gas phase, chromium plating with subsequent titanium alloys. results are presented as comprehensive coatings: metallographic, micro-X-ray spectral, X...

In this study, the effect of chromium carbide (Cr7C3) on abrasive wear behavior of Fe-C-Mo-FeCr composite was investigated. Composite, which was produced by a powder metallurgy route was containing 3 wt.% Mo, 1.5 wt. % C and 4,8,12 wt. % FeCr with the different particle sizes. In the experiments, wear resistance of samples were determined using different loads by a pin on disc wear tester. Micr...

Precession electron diffraction has seen a fast increase in its adoption as a technique for solving crystallographic structures as well as an alternative to conventional selected-area and converged-beam diffraction methods. One of the key issues of precession is the pivot point alignment, as a stationary apparent beam does not guarantee a fixed pivot point. A large precession tilt angle, along ...
