“…The results of the studies presented in [6] are of particular interest, since they indirectly confirm the existence of a theoretically predicted new species of crystalline carbon nitride β-C 3 N 4 [1]. Crystalline carbon nitride was obtained via magnetron sputtering with additional ion irradiation and subsequent annealing in a nitrogen atmosphere.…”

Diamond-like carbon coatings on hard-alloy substrates, including coatings doped with nitrogen about 1.0 μm thick have been obtained using a pulse vacuum-arc method. Three types of coatings have been investigated: a carbon diamond-like coating (C), a carbon coating doped with nitrogen (C : N), and a composite coating based on (C : N + C) layers. The coatings have been annealed in atmospheric air at a temperature of 400°C. The tribological characteristics (wear resistance and friction coefficient change dynamics), the adhesion strength, and the microhardness of coatings in the initial state and after annealing have been studied. The composite coating consisting of C : N + C layers surpasses the constituent coatings in properties, both in the initial state and after annealing at a temperature of 400°C.

“…The peaks at 28.5° and 47.3° are assigned to the (111) and (220) plane of Si substrate (JCPDS PDF# 65‐1060). Three peaks at 32.5°, 48.3°, and 51° can be indexed to known C 3 N 4 phases (β, α, graphite, etc), and remaining peaks at approximately 29° to 33° and 48° to 51° may relate to some unknown phases of C―N . The other relative weak peaks in the diffraction patterns can be attributed to several factors such as small grain size or the influence of intense peaks of substrate and/or impurity …”

Using ionic source assistant, Ti and N co‐doped amorphous C (α‐C:N:Ti) thin films were prepared by pulse cathode arc technique. Microstructure, composition, elemental distribution, morphology, and mechanical properties of α‐C:N:Ti films were investigated in dependence of nitrogen source, pulse frequency, and target current by Raman spectroscopy, X‐ray diffraction, scanning electron microscopy, X‐ray photoelectron spectroscopy, atomic force microscopy, nanoindentation, and surface profilometer. The results show the presence of titanium carbide and nitride in a‐C:N:Ti films. The α‐C:N+:Ti film (6 Hz, 60 A) shows the smaller size and the higher disordering degree of Csp2 clusters. The α‐C:N+:Ti films present smoother surface and smaller particle size than for α‐C:N2:Ti films. N ions facilitate the formation of N‐sp3C bonds in the α‐C:N+:Ti films, and α‐C:N+:Ti (10 Hz, 80 A) film possesses the more graphite‐like N bonds. Higher hardness and lower residual stress present in the α‐C:N2:Ti (10 Hz, 80 A) film.

Concerns surround whether insensitive (or any) energetic materials are more dangerous to handle when exposed to abnormal thermal environments. This study characterizes the residual material remaining after LX‐17 (92.5 % 1,3,5‐triamino 2,4,6‐trinitro benzene (TATB) and 7.5 % Kel‐F) is exposed to various thermal environments in a sealed small‐scale vessel cook‐off test reactor (heated at 0.1 to 100 °C/min until the reactor opened at 3000 psi (20.7 MPa)). Previous work has shown no additional sensitivity of these residues as evaluated by small‐scale safety analysis, but characterization on the molecular scale indicates the TATB is transformed to more reactive compounds as well as the residue could be precursors to toxic gases. The solids and chars were characterized by various analytical methods. Heat‐flow measurements indicated exothermic release is due to a mixture of residual TATB and related decomposition products (which may be more energetic). The N/C and O/N ratios indicated a material much more degraded than TATB. Primarily, the solids were a network of amorphous C inter‐dispersed with N and O. Types of bonding include C−C, C−N, N−H, N−C, N=C, N≡C, C−O=, and −OH. Solvent extracts of the solids showed TATB decomposition intermediates benzo‐furazans and benzo‐furoxans, substituted TATB (mono‐nitroso, hydroxyl, and chlorinated) along with several unidentified smaller molecules. These results indicate thermal treatment produces an amorphous carbon residue with heteroatoms incorporated through differing functionality, varying depending upon the thermal severity of exposure. These structures also could further decompose producing toxic light gases (such as cyanide).
