Properties and characterization of coatings made using jet kote™ thermal spray technique

Abstract: The JET KOTE” system is a new thermal spray technique which relies on the continuous internal combustion of a fuel gas with oxygen to produce a high velocity exhaust jet. Powder is injected into this pressurized gas stream, where it is heated and accelerated toward the part to be surfaced. Using this technique, coatings of several wear resistant materials have been made for applications in petrochemical and chemical, materials processing, aerospace, and other engineering fields. In this paper, data relating to JET KOTE coatings of tungsten carbide-cobalt (of various cobalt contents), chromium carbide-nickel chromium, and a new iron-base wear resistant alloy called TRISTELLE” alloy TS-2 are presented. It has been shown that the JET KOTE process can be used to produce dense coatings of WC-Co with properties equivalent to those produced using the detonation gun and are much superior to plasma sprayed coatings. JET KOTE coatings of WC-Co also appear to have the added advantage of containing a higher amount of WC phase and considerably less eta phase thereby increasing their resistance to cracking.

Metal-containing nanoparticles, their synthesis and use

Abstract: A powder batch is described comprising single crystal metal-containing particles having a crystal size of less than 50nm as measured by X-ray diffraction and having a weight average particle size of from about 10 nanometers to less than 100 nanometers as measured by transmission electron microscopy and including a continuous or non-continuous coating of a ceramic material. The powder batch is preferably produced by flame spraying.

Measurement of angular emission trajectories for magnetron-sputtered tantalum

Abstract: Sputtering target crystallographic orientation affects film deposition uniformity through the emission trajectories of the sputtered atoms. Understanding the relationship between the crystallographic orientation of the sputtering target and the emission trajectory for the sputtered atoms is important for being able to accurately model film thickness uniformity and step coverage. This paper describes the measurement of atom sputter trajectory from a tantalum single crystal. A quartz crystal monitor is used to detect sputter atom flux as a function of angle. The angular sputter emission measurements are consistent with emission from tantalum single crystals along the 〈111〉 close-packed direction as well as the second close-packed 〈100〉 direction. Best fit of the experimental data occurs when the ratio of the emission probabilities in the 〈111〉 and 〈100〉 directions (P〈111〉/P〈100〉) is 1.4, and the ratio of the major and minor axis for the sputter emission ellipsoid (the b/a ratio) is 1.5.
