PVD Technology Introduction
PVD coatingCemented carbideTo achieve a better understanding of the interaction between the film and the ductile Co-based binder phase in cemented carbide substrate and the associated interface microstructure evolution, a model alloy of 85.1Co-9.2W-4.7Cr(3)C(2)-1.0VC was prepared. Ti0.34Si0.06N...
New ceramic thermal barrier coating (TBC) compositions superior to state-of-the-art PYSZ material are considered to overcome the problems related to phase stability and service-induced sintering within the columnar feather-like structure of current EB-PVD TBCs. Among those candidates for gas turbine...
Investigation of coating failure on the surface of a water ballast tank of an oil tanker. J. Adhes. Sci. Technol. 2005;19:879–908. [35] Martin JD. Using XPowder: a software package for powder X-ray diffraction analysis. Available from: http://www.xpowder.com,2004.(D.L.GR1001/04...
This study aims to investigate the improvement of the tribocorrosion properties of WC-TiC-Co substrates by coating them with hard coatings such as AlCrSiN using cathodic arc deposition. WC-TiC-Co is commonly used in the fabrication of machining and cutting tools; however, there are some material...
One of the major drawbacks during sintering of metal powders is the carburization of the powder in contact with the graphite foils. In this study, a PVD coating of titanium was applied on the graphite foils in contact with the metal powder (pure iron). The results are promising, as the ...
The literature information and other data support the hypothesis that a hard coating, whatever its nature (i.e., TiN vs. TiAlN), has better performance inasmuch as it consists of smaller crystallites, shows higher hardness, it is smoother, it is free of stress, and has an adequate thickness...
Keywords: PVD coating; cavitation erosion; solid particle erosion; wear; fracture 1. Introduction Hydraulic machines especially in hydropower plants are exposed to erosion caused by cavitation and/or solid particles that move with the flowing water. Erosion of the hydro turbines has become a serious...
CGDS is a thermal spraying technique by which the powder coating materials are deposited on the surface at high speeds at considerably lower process temperatures. This high-speed process is carried out by heating and compressing gases such as air, nitrogen, and helium. The CGDS method has many ...
