Chromium carbide

-

Cr3C2 structure. Atoms of carbon are marked in gray.

Chromium carbide - a chemical compound of chromium and carbon with ceramic properties. It occurs in several forms corresponding to the formulas: Cr3C2, Cr7C3 and Cr23C6. All are gray solids with high hardness, fire resistance, corrosion resistance. Synthesis

Chromium carbide can be produced in mechanical synthesis: ball mill, metallic chrome, graphite. The produced powder is solidified into a non-porous material with macroscopic dimensions in a hot isostatic press. The role in the corrosion of stainless steel

The formation of chromium carbides at the interstitial boundary is one of the causes of intercrystalline corrosion and stress corrosion of austenitic alloys in which the corrosion resistance is related to the presence of chromium.

This story is confirmed by the next accounts: Nearchos, one of the army officers of Alexander Macedoński, and Megastenes - a historian and traveler. The fragment of the Megasthenes (IV-III century BC) preserved in fragments can be seen in the underground mines at the foot of the mountains on the easte...

Names of streets and squares

The names of the streets and squares were originally of a topographical nature, that is, they informed about: Researchers propose two names for these toponyms - urban or plateonimy. S. Urbańczyk points out that the older names were spontaneously formed and sprouted in the daily lives of the inhabitants of the place. The information contained herein was related to the characteristics of the place (eg appearance), important road directions (geographic orientation) or values, functions and economic meanings called places / objects in the settlement for the inhabitants' lives. Former names are protected by law, but are often not respected by managers of the municipality, county or province. Currently the names of streets and squares are given by the commune authorities, county governors or voivodships. There is a tendency to use commemorative names, ie to commemorate deserving people and important events (eg Zygmunt August Street, 3. Maja Street). The names of the districts are ...
