The fuel consumption and performance of the Internal Combustion engine is improved by adopting concepts of an adiabatic engine. An experimental investigation for different load conditions is carried out on a water-cooled, constant-speed, twin-cylinder diesel engine. This research is intended to emphasize energy balance and emission characteristic for standard uncoated base engine and adiabatic engine. The inner walls of diesel engine combustion chamber are thermally insulated by a top coat of Metco 204NS yttria-stabilized zirconia (Y2O3ZrO2) powder (YSZ) of a thickness of 350 mm using plasma spray coating technology. The same combustion chamber is also coated with TBC bond coats of AMDRY 962 Nickle chromium aluminum yttria of thickness of 150 mm. The NiCrAlY powder specially designed to produce coating’s resistance to hot corrosion. The combination of this ceramic material produces excellent high-temperature thermal barrier coating (TBC) resistant to thermal cycling stresses and strains. The engine valves, engine heads, and engine pistons were thermal barrier ceramic coated and computerized experimental results were compared to the base engine. Experimental results justified TBC engine to give a…

Various research regarding new methods of fabrication and modifications of Aluminium alloy to improve the existing properties are going on. The wide application of aluminium in aerospace and automobile Industry, demands improved mechanical properties with little to zero increment in weight. This work is based on the fabrication of hybrid metal matrix composites of 7075 aluminium alloy with the addition of TiC (Titanium Carbide) and Al2O3(Aluminium Oxide) reinforcements is fabricated using stir casting technique. Weight percentage of 5%, Al2O3 8% and Tic 12%, Tic 15% and Al2O3 10%. Samples are prepared for each mass distribution . Varying weight fraction samples are prepared to have a proper comparative study of the mechanical properties. In the fabrication we gradually increased the weight of TiC and Al2O3 as we progressed with the experiment.. The objective is to have a clear idea of mechanical properties variation with variation in reinforcement. Hardness tests is done using optical Brinell Hardness Testing machine . A proper characterisation of the samples was attained by using advanced electron microscopes. Tensile properties of the samples…

In this modern era of rapid growth of technology and need of economical machining processes and materials, there is an increasing demand for new materials for different mechanical applications. Composites with fly ash as reinforcement are likely to overcome the cost barrier for wide spread applications in automotive and small engine applications. To improve wettability, elements such as Mg and Si are added into Al melt to incorporate the ceramic particles. The chemical composition and engineering properties of fly ash, its physical and chemical properties make it an ideal raw material for producing various application based composites. The main objective this paper is to fabricate an aluminium- fly ash composite material suitable for parts like engine connecting rod which demand high strength and temperature sustainability at comparatively less weight. The composite will be made using casting process and Engine connecting rod will be designed in AutoCAD software. The design will be analyzed with the help of ANSYS with aluminium and aluminium- fly ash composite (at different compositions).

Low cost, fireproof, and light aircraft interior Fire is a dramatic issue in aircraft nowadays, especially with composite air crafts. An additional issue is the dangerous use of flammable Li-Ion batteries in a lot of appliances. we propose in order to avoid dramas to produce aircraft interiors, fire doors, cargo bay walls, as well than cargo container able to contain a fire inside them, with our ceramic composite called TOUGHCERAM ®. We have developed a low-cost, ceramic, damage tolerant, this ceramic is flexible between minus 100°C and plus 350°C. TOUGHCERAM ® poly-crystalize between 60°C and 110°C and can be reinforced with fibbers like carbon or basalt one. TOUGHCERAM ® survive 90 minutes to a propane 1900°C torches. TOUGHCERAM ® does not burn, nor smoke. In this paper we will explain how it is possible to develop a fully mineral ceramic offering such unique mechanical and fire properties.

A ceramic bound matrix has been investigated to be used as a friction material. The materials were produced by means of ceramic technology using frits containing silicates, and ceramic friction modifiers such as tin oxide, zircon, iron oxide, magnesium oxide. Four formulations were tested by means of a tribometer (pin-on-disc tester) using a gray cast iron counterpart. Test section included speeds between 1 and 12 ms-1, and loads between 25 and 400 N. The coefficient of friction of the tested specimens were between 0.7 and 0.4, and exhibited sensitivity to speed at low loads (25 N), while they are quite stables at high loads (400N). The characterization of the tribolayers was carried out by means of scanning electron microscopy. The four developed materials were named A, B, C, and D. They exhibited different wear rates and coefficients of friction. All the materials exhibited sensitivity to speed, while showed a lower sensitivity to load. The coefficient of friction level seems to be suitable for brake applications, oscillating between 0.6 and 0.4, depending on the test section.…

The objective of this investigation was to improve the thermal properties of plasma sprayed thermal barrier coatings (TBC) for internal combustion engines. There is a need for further reduction of thermal conductivity and volumetric heat capacity and the negative effects on heat loss and combustion phasing of surface roughness and permeable porosity, typical for plasma sprayed coatings, should be minimized. Four measures for improvement of TBC properties were evaluated: i) modification of the coating's microstructure by using a novel suspension plasma spraying method, ii) application of gadolinium-zirconate, a novel ceramic material with low thermal conductivity, iii) polishing of the coating to achieve low surface roughness, and iv) sealing of the porous coating surface with a polysilazane. Six coating variants with different combinations of the selected measures were applied on the piston crown and evaluated in a single cylinder light duty diesel engine. The experimental data was modeled with multiple linear regression to obtain confidence intervals for the measurement results and to correct the data for variations of surface roughness, combustion phasing and compression ratio for…

A chassis-integrated sandwich structure of solid electrolytes currently in development is projected to deliver all-electric driving ranges that far out-distance today's typical 200-mile (320 km) EV real-world driving range. IAV, Thyssenkrupp AG and Fraunhofer Institute for Ceramic Technologies and Systems (IKTS) are the core project partners working to develop EMBATT, a chassis-embedded energy technology.

Published 2019-04-25

Metals and alloys all have different melting ranges depending on their chemistry. High temperature metals are much harder at room temperature, have exceptionally high melting points (usually above 2000 degree Celsius), and are resistant to wear, corrosion and deformation. The following five on-demand courses are included in the High Temperature Materials bundle.  Each course is approximately one-hour in duration. See Topics/Outline for additional details.
