This book was released on 1994 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective was to determine the tribological properties of hard, wear-resistant coatings on steel substrates in order to expedite their use on coated roller bearings, transmission gears, cams, etc. Specific coatings investigated were TiN, TiC, ZrN, ZrC, HfN, and HfC; they were deposited by high-rate-reactive magnetron sputtering. Both nitrides and carbides improved the wear performance of steel, often by orders of magnitude. These coatings have proven to be beneficial for dry sliding, lubricated sliding, rolling, and mixed rolling/sliding wear. The rolling contact fatigue studies showed remarkable improvements of lifetime that could be achieved with very thin coatings (less than one micron); thicker coatings were not useful. Coating and substrate properties (hardness) should be matched for best performance. Properties and performance of the hard coatings are controlled by process parameter settings; these parameters can be controlled in magnetron sputtering to achieve excellent results.

Download or read book The Chemistry of Titanium Zirconium and Hafnium written by R. J. H. Clark and published by Elsevier. This book was released on 2018-03-12 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chemistry of Titanium, Zirconium and Hafnium deals with the chemistry of titanium, zirconium, and hafnium and covers topics ranging from the occurrence and metallurgy of all three elements to their nuclear, physical, and chemical properties as well as analytical chemistry. The compounds of titanium, zirconium, and hafnium are also discussed. This volume is comprised of two chapters and opens with a historical overview and discovery of titanium, along with its occurrence and distribution, metallurgical aspects, and nuclear and physicochemical properties. The compounds of titanium are also considered, including alloys and complexes; hydrides and oxides; halides and oxyhalides; titanates and antimonides; and carbides and borides. The second chapter is devoted to zirconium and hafnium, their occurrence and metallurgy; and physical, chemical, and biological properties. Compounds of zirconium and hafnium are described, from alloys and hydrides to zirconates and hafnates; nitrides, phosphides, and arsenides; carbides, silicides, and germanides; molybdates, tungstates, halates, and perchlorates; alkoxides, mercaptides, and dithiocarbamates; and amides, alkylamides, triazenes, phthalocyanines, and bipyridyls. This book will be a valuable source of information for inorganic chemists.

This book was released on 2003 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research program entailed the investigation of the surface chemical and tribological (friction, lubrication, and wear) properties of titanium carbide (TiC), titanium nitride (TiN), and vanadium carbide (VC). These hard coating materials are potentially useful in enhancing the performance and extending the lifetime of lubricated spacecraft mechanisms. The program sought to establish the fundamental chemical and tribological properties of interfaces involving these materials and to understand the origin of differences between the materials, such that they may be specified and employed in DOD spacecraft mechanisms. The objective of the research was to establish a systematic understanding of the reactivity and friction of model metal carbide interfaces in terms of both the inherent properties of each material as well as the fundamental origin of differences between the materials. This objective was met by providing a base level of fundamental information regarding the chemical and tribological properties of these materials. It is envisioned that this information will allow the intelligent design of and selection of materials in future USAF satellite mechanisms.
