Available in PDF, EPUB and Kindle. Book excerpt: Diffusion-bonded electroless nickel plate was investigated as a wear- resistant coating for titanium alloys 6A1-6V-2Sn and 8A1-1Mo1V. Plate adhesion and diffusion zone structure were assessed by metallographic and X-ray diffraction techniques. Effects of the diffusion heat treatments on mechanical properties and wear characteristics of the titanium alloys were determined. The diffusion bonding produced a surface of nickel-rich intermetallics which significantly improved the wear resistance of the titanium alloys without any appreciable degradation of their structural integrity.

Download or read book Coatings Tribology written by K. Holmberg and published by Elsevier. This book was released on 1994-07-15 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a general view on thin surface coatings used for tribological applications and it is based on the current state of understanding. The mechanisms of friction and wear in sliding and rolling contacts of coated surfaces are described. Basic information on coating techniques, tribology and surface mechanisms is given. Based on collected experimental works information is given on the properties of thin soft coatings, such as polymer, lamellar solid and soft metal coatings; thin hard coatings, such as nitride, carbide, oxide, boride and diamond and diamond-like coatings; and multi-component and multi-layer coatings. The influence of interface layers and lubricants is highlighted. The methods available for characterization of coated surfaces and for mechanical and chemical evaluation of their tribological properties are described. Tribological evaluation methods for accelerated and field testing and the need for standardization of quality assurance procedures are discussed. A methodology for the selection of thin coatings for tribological applications is presented and knowledge based expert system approaches for coating selection are reviewed. For different application examples, the basic tribological contact mechanisms are described and the possibilities for improving their tribological properties by using surface coatings are discussed. The application examples include sliding and rolling bearings, gears, tools for cutting and forming, erosion resistant applications, magnetic recording systems and bio-medical implants.
Download or read book Wear and Fretting Fatigue Resistant Coatings for Titanium Alloys written by Robert K. Betts and published by . This book was released on 1974 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies were performed to identify treatments to alleviate the effects of wear on fatigue properties of Ti-6Al-4V, Ti-5Al-4Mo-4Cr-2Sn-2Zr (Ti-17) and Ti-8Al-1Mo-1V. The mechanisms of wear studied were fretting fatigue and sliding wear fatigue. Fretting fatigue tests were performed using high cycle fatigue specimens with shoes bolted across the gauge sections at 25,000 psi contact pressure. The shoes induced fretting as the result of alternating bending strain motion along the edges of the contact interface. Sliding wear fatigue tests were performed by a two-step method including first the cyclic rubbing of fatigue specimens by wear shoes for 10,000 strokes of 5 mils length under 50,000 psi contact pressure. Subsequently, the specimens were tested in low cycle or high cycle fatigue to determine the effect of wear on the endurance limit. In fretting tests of Ti-6Al-4V at room temperature, and of Ti-6Al-4V and Ti-17 at 650F, a Cu shim insert between the specimen/shoe interface inhibited fretting fatigue. In sliding wear tests of all three Ti alloys at room temperature, a plasma sprayed coating of Al-bronze containing 10% carburundum polyimide prevented loss of fatigue strength. The Al-bronze/carburundum polyimide not only protected fatigue specimens to which it was applied, but also it did not cause damage to uncoated fatigue specimens against which it was rubbed. Other coatings and surface treaments evaluated did not afford complete wear protection.

Available in PDF, EPUB and Kindle. Book excerpt: NITRIDES, BORIDES, ADHESION, STRESS CORROSION, PLATING, NICKEL, COMPRESSOR BLADES, IMPELLERS*ABRASION RESISTANT COATINGS, TITANIUM NITRIDES, TITANIUM CARBIDES, TITANIUM ALLOY 6AL 4V, TITANIUM BORIDEThe objective of the program was to develop the application of TIKOTE-C on the Ti-6Al-4V alloy with minimum degradation of mechanical properties. The approach for accomplishing this objective was to protect the titanium microstructure with an intermediate nickel barrier, as well as to provide a ductile layer which might inhibit crack propagation. In addition, embrittling effects due to gas absorption during the coating process were minimized by using a lower process temperature. The program was divided into two major categories: (1) TIKOTE-C coating application development, and (2) extensive mechanical tests. A brief evaluation of the fatigue characteristics and erosion resistance of nickel-plated and titanium diboride-coated titanium test specimens was made.
