Book excerpt: Techniques for applying chromium-molybdenum alloys to titanium alloy substrates were developed and the resulting systems evaluated as protective coating. Deposition techniques including electroplating and sputtering were considered and diffusion properties studied. A coating alloy containing 1% molybdenum was shown to greatly improve the wear resistance. Erosion, oxidation and stress corrosion properties were also improved. The coatings system had no apparent effect on fatigue properties of Ti 8Al-1V-1Mo at either room temperature or 315 C. (Author).

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.

This book was released on 1971 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the work was to define and establish conditions of fretting wear on uncoated, shot-peened Ti-6Al-4V under which conditions fatigue effects may be expected in aircraft gas turbine engine compressor applications. The study was divided into two tasks, each concerning a specific wear phenomenon and resulting fatigue effects. Task 1 involved classic fretting fatigue between bolted surfaces relating to aircraft compressor disc assemblies. Task 2 involved studies of wear simulating that between surfaces of dovetails, in which contact pressure and displacement are related to dynamic loads.

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.

Download or read book Fretting Wear Resistant Micro Arc Oxidation Coatings for Aluminum and Titanium Alloy Bearings Preprint written by and published by . This book was released on 2007 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report was developed under a SBIR contract, and has been released to the public by Infoscitex. Aluminum and titanium alloys are used as replacements for steel in gear boxes of aircraft and helicopters in both military and commercial air vehicles, due to their low density, mechanical strength and thermal conductivity. However, these alloys are susceptible to fretting wear when matched to harder steel surfaces under high loads at elevated temperatures. Anodized coatings are too thin and porous to protect these metals. Infoscitex applied a proprietary micro-arc oxidation process to produce hard, thick, and adherent oxide coatings on aluminum and titanium alloys that rendered the coated metal components resistant to fretting type wear. Selected aluminum and titanium alloy test specimens were micro-arc treated then measured for surface hardness, roughness, and adhesion to metal substrate. Block-on-Ring fretting wear tests on polished test specimens against M-50 steel were conducted in the presence of lubricant, under high loading, at ambient and 400 degrees F temperatures. Coefficient of friction and wear volume were measured versus number of test cycles. The results of efforts to improve the fretting wear resistance of aluminum and titanium alloy bearings for use in aircraft gear box applications will be discussed.
