The SEM in the IPCMS through some examples

Thin film and nano-objects


Morphological feature of the coating, formed on Ti6Al4V surfaces after soaking in NaOH. The obtained TiO2 layer heterogeneous coating is composed on approximately 1-2 nm spherical agglomerates laying on nano-scale porous bone-like structure

Image of dual autocatalytic-biomimetic deposition process of calcium phosphate coating on Ti6Al4V alloy. This coating exhibits network-like crystals with 100-200 nm porous structure, indicating a possible potential for maintaining proteins and antibiotics that are beneficial to post-surgical healing.

Classical metallography

Imaging and EDS analysis of CePd3 alloys dopped with Mn, 1% in weight. The gray/colored background is the main phase (CePd3 + Mn2% at). The dark/colored precipates are a cerine phase (stick shape, CeO2) and a PdMn phase (diffuse and unregular shape).

Miscellaneous – Art & Science

Delaminating PLD diamant like carbon film on WC. The peeling of the coating shows a stratificated structure. Images in optical microscopy (DIC) and in SEM. There is a direct correspondance between the interference colors in DIC and the grey levels from the SEM (more black = more thick)

Highly oriented carbon nanotubes grown by HF-CVD in cross view.
F. Le-Normand, C. Cojocaru – SEM image J. Faerber
Structures grown by a prolongated carburation step under H°, in the process of diamant growing by HF-CVD. The substrate is a Si single crystal, the bright hat is a SiC growing and the columar foot is the remaning Si, protected from the H° etching by the SiC hat.
