Bias enhanced diamond nucleation on Mo and CrN coated stainless steel substrates in a HFCVD reactor

Experience in depositing carbon coatings by the gas-jet method

“…The obtained spectra point to the presence of the crystal phase of carbon, and the inflection point in the region of 1140 cm −1 in the RS spectrum (curve 2) is indicative of the process of formation of nanocrystalline diamond. The given spectrum is similar to the spectra described in [5].…”

“…In a number of works devoted to obtaining diamond films, to activate the gas phase, the hot wire method was used successfully [3][4][5][6]. Nevertheless, the search for new methods of obtaining diamond and diamond-like coatings remains topical [7][8][9].…”

Mechanisms of time-modulated polarized nano-crystalline diamond growth

“…Multilayer diamond coatings on WC-12%Co substrates are synthesized without prior seeding and using a two-step growth process. First, nucleation step was carried out with a high methane concentration (3%) and a BEN (bias enhanced nucleation) at − 200 V [25][26][27][28][29] . Second, a "timemodulated polarized growth step" (TMPGS) is achieved at lower methane concentration (0.8%).…”

Desenvolvimento de um reator para o crescimento de filmes diamantiferos tubulares

“…Observa-se que as características de filmes crescidos diferem-se das diamantíferas quando se alteram os parâmetros de crescimento no reator com a intenção de aumentar a taxa de crescimento. Artigos relatam [19,[33][34][35][36][37] experiências de crescimento de diamante por processo CVD sobre substratos não diamantíferos como Au, Cu, Si, Mo e W e apresentam que:…”
