Luthra General Electric Corporate Research and Development, Schenectady, NY (USA) (Received April 8, ; accepted in final form July 6, ) Abstract The behavior of several different types of plasma-sprayed coatings applied to typical a + titanium Cited by: % yttria partially stabilized zirconia thermal barrier coatings (TBCs) were air plasma sprayed on titanium alloy substrates (Ti–Al–Mo– Zr–Si in wt.%).

The microstructures and mechanical properties of the coating system were studied by using SEM, XRD, MIP, tensile test and Vickers microhardness.

Consequently, thermal protection becomes a concern. 8 wt.% yttria partially stabilized zirconia thermal barrier coatings (TBCs) were air plasma sprayed on titanium alloy substrates (Ti–Al–3. In the deposition of a tungsten coating on a titanium substrate regions of chemical reaction are observed.

In the deposition of an 80% Ni% Cr alloy coating by the plasma-spraying process adhesion is purely mechanical in character. It has been established that the amount of tungsten in the zones of chemical reaction is a function of the spraying range.

Mckee et al. investigated the plasma sprayed coating for titanium alloy oxidation protection, the ductile coatings of MCr and MCrAlY type were found to confer protection against oxidation and embrittlement for hundreds of hours during rapid thermal cycling in flowing air.

Titanium Plasma-Sprayed Coatings on Polymers for Hard Tissue Applications particles were transported in air at a pressure of approximately MPa. the biomedical Ti alloy Ti–13Nb–13Zr. Nickel Alloys – Stainless Steels, Nickel Copper Alloys, Nickel Chromium Alloys, Low Expansion Alloys and Magnetic Alloys Proprietary lubricants of dip or spray-on dry film type, based on molybdenum disulphide, PTFE or graphite and the like have been developed specifically for titanium.

Titanium and its alloys are often used for corrosion protection because they are able to offer high chemical resistance against various corrosive media.

In this paper, shrouded plasma spray technology was applied to produce titanium coatings. A solid shroud with an external shrouding gas was used to plasma spray titanium powder feedstock with aim of reducing the oxide content in the as-sprayed.

The paper presents the results of titanium plasma spraying (TPS) on polymer substrates. Polyethylene (PE), polyamide PA6, and fiber glass-reinforced polyamide (PAGF30) were used as substrates.

The PE and PAGF30 substrates exhibited appropriate behavior during the TPS process, whereas the PA6 substrate did not “accept” Ti during plasma spraying, and the coating did not form.

Titanium alloys are fast emerging as the first choice for majority of applications due to the combination of their outstanding characteristics such as high strength, low density, high immunity to corrosion, complete inertness to body environment, enhanced compatibility, low Young´s modulus and high capacity to join with bone or other tissues.

This article is devoted to studiing the ion-plasma sprayed coating on the surface of copper-nickel alloy obtained by complex titanium nitride and zirconium nitride treatment. To evaluate the coating microhardness we use the method that provides the obligatory penetration of diamond-pointed pyramid through nitride layer.

It is shown that nitride coating microhardness is much higher than the. Hydroxyapatite coatings were plasma sprayed on the Ti6A14V substrate with and without an intermediate ZrO2 layer; meanwhile the temperatures of substrates were varied at 90,and °C. The coatings were subjected to the standard adhesion test per ASTM C The purpose of the investigation was to study the effects of those processing variables on the bonding strength and failure.

Vacuum plasma sprayed (VPS) Ti coatings were deposited and their surface modification processes were performed by NaOH solution treatment and alkali-heat-calcification respectively. The simulated body fluid test indicated that apatite was formed on the surfaces of Ti coatings.

A net-like structure was observed on the surfaces of Ti coatings treated by alkali-heat-calcification, whose. of using WC/Co coatings is relatively high, approximately US $/m2 for a µm thick coating with a 65% spraying efficiency [16].

Compared to this, the density of the Al-SiC coating systems have density of g/cc, depending on the SiC content of the Al-SiC coatings. Plasma Sprayed Chromium Carbide coatings are specifically developed to be used in coats which are thin, for if used for thick coatings there is a high probability of it developing cracks as is usual with all fine powders.

Oxides on the surface need to be cleaned prior to preheating and spraying the titanium. In summary, the tensile and shear adhesion of plasma-sprayed titanium coatings to magnesia-stabilized zirconia c eramic substrates was found to meet or exceed current and previously publ ished adhesion data from cast cobalt chromium alloy and titanium alloy substrates.

Because of its excellent adhesion strength, porous-coated M g-PSZ ceramic. Plasma-sprayed ceramic coatings have been widely used in friction and wear protection of mechanical parts. In this paper, the nanostructured Al 2 O 3 –13 wt% TiO 2 coatings were. Stainless steel, aluminum and titanium plates having dimensions 15x15x3mm were used as coatings substrates.

They were alumina grit blasted. The substrates were plasma sprayed using Praxair SG torch mounted on the 5-axis ABB IRB-6 industrial robot. The spray parameters are collected in Table 2. Plasma Aluminum-Graphite Composite. A&A Coatings material was specifically developed to provide a plasma sprayed, abradable clearance control coating for gas turbine engines with titanium alloy, and possibly aluminum alloy rotors operating at °C (°F).

Tape & Label. Plasma-sprayed sphene coating on Ti-6Al-4V has been successfully prepared and demonstrates a close bonding with the Ti-6Al-4V substrate. The coating possesses a significantly improved bonding strength and chemical stability and enhanced HOB proliferation and differentiation, compared with plasma-sprayed HAp coating and uncoated Ti-6Al-4V.

Plasma spray. Plasma spray is a thermal spray coating process used to produce a high quality coating by a combination of high temperature, high energy heat source, a relatively inert spraying medium, usually argon, and high particle velocities.

The molten droplets of metal wire are then sprayed onto the substrate using a high velocity air stream to atomize and propel the material. Arc spray coatings are very cost effective and are typically used to apply metals like pure aluminum, zinc, copper, and metal alloys such as stainless steel.Rivets remain one of the most common means to assemble aircraft components.

These rivets, made of titanium or aluminum alloys, are subject to enormous stresses as a result of high humidity and huge temperature changes that make corrosion protection a challenge.Evaluation of Advanced Solid Lubricant Coatings for Foil Air Bearings Operating at 25 and C,” A System Approach to the Solid Lubrication of Foil Air Bearings for Oil-Free Turbomachinery,” Friction and Wear of Titanium Alloys,” Friction, Lubrication and Wear Technology (ASM Handbook.
