1997/7/1The tribological characteristics of the TiN, TiC and Ti(C,N) coatings related to three-body abrasions were studied in this work. Eight types of coating films were deposited by means of the cathodic arc ion plating process by varying the mass flow rates of nitrogen and acetylene gases during the coating processes. The lower specimens were coated by the titanium film as the underlayer and the

Influence of Oxidation Behavior of Feedstock on

Plasma spray is one of the suitable technologies to deposit carbide coatings with high melting point, such as ZrC. However, in the spray processes performed under atmosphere, oxidation of the carbide powder is inevitable. To investigate the influence of the oxidation behavior of feedstock on microstructure and ablation resistance of the deposited coating, ZrC coatings were prepared by

Potential of Coatings in Total Hip Replacement : Clinical

2018/5/9rent kinds of treatments or coatings may improve total hip replacements considerably. The most studied surface treatments include ion implantation and methods to control surface topography, such as grit or sand blasting or plasma treatments. Among the large variety of coatings, hydroxyapatite, titanium oxide and nitride, zirconium oxide, pyrolytic carbon, and diamondlike carbon coatings have

Coating Services, Tool Coating

Guhring's coatings research department has developed a new nano multi-layer coating for nickel base materials and hardened materials that require high surface hardness coatings. Called nano-Si, this TiAlSiN (titanium aluminum silicon nitride) based coating is designed to yield similar performance to diamondlike coatings without the restrictions on the host base material substrate.

Zirconium diboride

Zirconium diboride (ZrB 2) is a highly covalent refractory ceramic material with a hexagonal crystal structure.ZrB 2 is an ultra high temperature ceramic (UHTC) with a melting point of 3246 C. This along with its relatively low density of ~6.09 g/cm 3 (measured density may be higher due to hafnium impurities) and good high temperature strength makes it a candidate for high temperature

Production of conversion oxide

2006/10/6We consider the possibilities of surface hardening of zirconium and titanium alloys with conversion oxide-ceramic coatings. These coatings have been produced by the method of plasma-electrolytic treatment in alkaline solutions. We have established that the plasma temperature in discharge spark channels reaches (6–9) 103 K. The thickness of the coatings is 100 to 120 and 30 to 40 m,
