Journal ArticleDOI
Deposition of Si-DLC films with high hardness, low stress and high deposition rates
TL;DR: In this paper, a study of the influence of self-bias and gas composition on the mechanical and structural properties of the Si-DLC films was carried out, and it was shown that films deposited at high self bias present high deposition rates, low stress and surprisingly high hardness.
Journal ArticleDOI
Improved high-temperature stability of Si incorporated a-C:H films
Sergio S. Camargo,A.L. Baia Neto,A.L. Baia Neto,R.A. Santos,F. L. Freire,R. Carius,Friedhelm Finger +6 more
TL;DR: In this paper, the temperature stability of silicon incorporated amorphous carbon films (a-C 1− x Si x :H) is investigated, and it is shown that films with x ≥ 0.15 have an improved hydrogen stability when compared with those with smaller silicon contents.
Journal ArticleDOI
Influence of artificial saliva on abrasive wear and microhardness of dental composites filled with nanoparticles.
TL;DR: Artificial saliva storage increases the materials' wear resistance, suggesting that in both materials bulk post-cure takes place and saliva absorption occurs only on the surface of the composites.
Journal ArticleDOI
Relation between mechanical and structural properties of silicon-incorporated hard a-C:H films
A.L. Baia Neto,A.L. Baia Neto,R.A. Santos,F. L. Freire,Sergio S. Camargo,R. Carius,Friedhelm Finger,Wolfhard Beyer +7 more
TL;DR: In this article, the structural properties of silicon-incorporated hard hydrogenated amorphous carbon films arc reported a strong reduction of the residual internal stress with an almost constant mechanical hardness was observed and the possible causes of this behavior was investigated.
Journal ArticleDOI
Magnetron sputtered SiC coatings as corrosion protection barriers for steels
TL;DR: In this article, silicon carbide films between 2.3 and 3.0 μm were deposited on AISI 304 stainless steel (SS), carbon steel (CS) and crystalline silicon from a SiC target in a magnetron sputtering system.
