Structure, chemical and phase composition of hard titanium carbon nitride coatings deposited on HS 6-5-2 steel

Structure and mechanical properties of low temperature magnetron sputtered nanocrystalline (nc-)Ti(N,C)/amorphous diamond like carbon (a-C:H) coatings

“…This combination of transition metal nitrides and carbides offered by the TiCN system has been investigated with particular attention for coatings containing up to 20 at. % C [5][6]. These studies show that coatings deposited in a reactive gas atmosphere using electron beam physical vapour deposition (EBPVD) processes at relatively low substrate bias (-70 V) and temperatures (~400 o C), exhibit a columnar structure [5].…”

Investigations on Wear Mechanisms of PVD Coatings on Carbides and Sialons

“…It was demonstrated from the GDOES analysis that in the contact zone, from the surface of the coatings, there is a rise in the concentration of the elements that are components of the substrate, with a simultaneous decrease of the concentration of those elements which are components of the coating. As suggested by the authors of earlier works [15][16][17][18][19][20][21][22][23][24][25], this may be due to the presence of a transit zone of a diffusive character between the substrate material and the coating, although we cannot rule out the possibility of simultaneous non-homogeneous evaporation of the material from the surface of the samples during the glow discharge spectrometer tests.…”

“…The rapid development of PVD technology started in the eighties, associated with a wide use of refractory compounds of carbon, nitrogen and boron, in particular with transition metals, as deposition of a thin, hard, anti-wear coating is one of the most important ways to reduce tool wear. Reducing the wear rate and increasing the durability, a low coefficient of thermal conductivity and wear on the effects of high temperature, and in many cases reducing the oxidation and corrosion processes largely determines the use of coatings obtained in the PVD process and, in some cases, the CVD process for coating of tool materials [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25].…”

Effect of Isothermal Heat Treatment at 760 °C on the Oxidation Behavior of Ti-Al-Zr Alloy

“…[37] GDOES has been used by investigators for analysis of metallic coatings [38,39] and thin films. [40] It has been used by researchers for depth analysis of passive films [41] and corrosion layers, [42] for electrodeposited and electrochemical films, [43][44][45][46][47][48] to characterize the industrial surface treatment phenomena [49][50][51][52] and for the characterization of high-temperature oxide. [53][54][55][56][57] The investigation by several researchers on the oxidation kinetics and alpha case formation in various titanium alloys established that material composition (i.e., alloying element) and microstructure significantly influence the oxidation kinetics and depth of the alpha case.…”
