WebIn this study, we present the results of the effect of duplex surface modification of 304-L stainless steel substrates by an electron-beam treatment (EBT) and subsequent deposition of diamond-like carbon coatings on the surface roughness and corrosion behavior. During the EBT process, the beam power was varied from 1000 to 1500 W. The successful … WebCorrect option is C) Carbon in graphite is sp 2 hybridized i.e. has 33% s character, Thus the C−C bond is more strong in graphite than in diamond, i.e. during combustion less heat is released from graphite and hence enthalpy of graphite is lower. Diamond is crystalline solid which is highly ordered structure while such arrangements are not ...

WebSep 13, 2024 · Among crystalline materials, those with the lowest entropies tend to be rigid crystals composed of small atoms linked by strong, highly directional bonds, such as diamond [S° = 2.4 J/(mol·K)]. In contrast, graphite, the softer, less rigid allotrope of carbon, has a higher S° [5.7 J/(mol·K)] due to more disorder in the crystal. Soft ...
