Atom Probe Tomography investigations on grain boundary segregation in polycrystalline Ti(C,N) and Zr(C,N) CVD coatings
(2019-03-15)
Article
Open AccessAtom Probe Tomography (APT) was used to obtain a direct evidence of chlor segregation and cobalt diffusion at the grain boundaries (GBs) of polycrystalline coatings deposited by moderate temperature chemical vapor deposition ... -
Contact damage investigation of CVD carbonitride hard coatings deposited on cemented carbides
(2020-01-01)
Article
Open AccessThe evolution of damage induced as contact load is increased has been investigated on single- and multilayered coated cemented carbides by means of spherical indentation. The main objective of the study was to assess the ... -
Contact fatigue behavior of a-Al2O3-Ti(C,N) CVD coated WC-Co under dry and wet conditions
(2021-02-01)
Article
Open AccessThe response to cycling contact fatigue load of a WC-6%Co carbide coated with a Ti(C,N)/a-Al2O3 CVD multilayer was investigated in dry and wet conditions. Imprints in dry conditions were characterized by small thin cracks ... -
Cyclic contact fatigue of cemented carbides under dry and wet conditions: Correlation between microstructure, damage and electrochemical behavior
(2020-11-01)
Article
Open AccessThe correlation between the damage induced under cyclic contact fatigue and their electrochemical behavior (anodic polarization curves) for different WC-Co-based cemented carbides grades was investigated at the macrometric ... -
Dynamic Range Extension of a SPAD Imager Using Non-Uniformity Correction Techniques
(IEEE, 2016-01-27)
Article
Open AccessThe extraordinary sensitivity of single-photon avalanche diodes (SPADs) makes these devices the ideal option for vision systems aimed at low-light applications. Nevertheless, there exist large dark count rate and photon ... -
Impact of temperature on chlorine contamination and segregation for Ti(C,N) CVD thin hard coating studied by nano-SIMS and atom probe tomography
(2022-02-01)
Article
Open AccessHigh resolution characterization by Atom Probe Tomography (APT) and Secondary Ion Mass Spectrometry (SIMS) imaging were combined to highlight the nature of chlorine contamination and impact of deposition temperature for ... -
Investigations on micro-mechanical properties of polycrystalline Ti(C,N) and Zr(C,N) coatings
(2018-05-01)
Article
Open AccessMicro-mechanical properties of Ti(C,N) and Zr(C,N) coatings deposited by chemical vapor deposition on a WC-Co cemented carbide substrate were examined by micro-compression testing using a nanoindenter equipped with a flat ...
