An investigation of the plasma electrolytic oxidation mechanism for coating of alumina-zirconia nanocomposite
Barati, Nastaran (2019-02-10)Plasma Electrolytic Oxidation (PEO) is an electrochemical surface modification technique which is able to coat ceramic coatings on valve metals from either cationic or anionic species in an aqueous electrolyte. Applying ... -
DEVELOPMENT OF PLASMA FUNCTIONALIZED NANO-ADDITIVES FOR OILS AND STUDY OF THEIR TRIBOLOGICAL PROPERTIES
Sharma, Vinay; 0000-0002-8010-5560 (2017-10-20)Lubricants used in motor engines contain various chemical species to help enhance energy efficiency and provide increased longevity. Unfortunately, at the same time, these additives become a source of catalytic poisoning, ... -
Fundamental Understanding Of Soot Induced Wear Mechanism Of Diesel Engines
Patel, Mihir (Materials Science & Engineering, 2014-09-17)Emission of Oxides of nitrogen and particulates matters from diesel engines have been reduced by implementing exhaust gas recirculation (EGR) protocols but at the expense of increased wear of engine components. This ... -
Investigation of Microstructure Effects on Hardness and Oxidation Resistance of New Generation Ceramic Coatings
Zhang, Minghui (2017-08-16)This work was motivated by the demand for a new generation of materials capable for harsh environment applications, and focused on developing a better understanding of the effects of elemental composition and microstructure ... -
MECHANISM OF WEAR AND TRIBOFILM FORMATION WITH IONIC LIQUIDS AND ASHLESS ANTIWEAR ADDITIVES
Sharma, Vibhu; 0000-0002-7859-9549 (2016-07-26)Increasingly stringent government regulation on emissions (EPA Emissions Standard Reference Guide and latest CAFE standards requiring an average fuel economy of 54.5 mpg (combined cars and trucks) by 2025) impose significant ... -

Properties Of Concrete With Tire Derived Aggregate And Crumb Rubber As A Ligthweight Substitute For Mineral Aggregates In The Concrete Mix
Siringi, Gideon Momanyi (Materials Science & Engineering, 2012-07-25)Scrap tires continue to be a nuisance to the environment and this research proposes one way of recycling them as a lightweight aggregate which can substitute for mineral aggregates in concrete. Aggregates derived from scrap ... -
A Study Of The Antiwear Behavior And Oxidation Stability Of Fluorinated Zinc Dialkyl Dithio Phosphate In The Presence Of Antioxidants
Somayaji, Anuradha (Materials Science & Engineering, 2008-08-08)The antiwear additive Zinc dialkyl dithio phosphate (ZDDP) is one of the most important components of engine-oil additives and a major source of phosphorus. Phosphorus plays a crucial part in mitigating engine wear, yet ... -
Synthesis And Evaluation Of Bioceramics For Orthopedics And Tissue Culture Applications
Demirkiran, Hande (Materials Science & Engineering, 2009-09-16)Hydroxyapatite is the most well known phosphate in the biologically active phosphate ceramic family by virtue of its similarity to natural bone mineral. Among all bioglass compositions Bioglass®45S5 is one of the most ... -
Tribological And Antiwear Mechanisms Of Fluorinated Zinc Dialkyl Dithiophosphate In Comparison To Zinc Dialkyl Dithiophosphate In Engine Oils
Mourhatch, Ramoun (Materials Science & Engineering, 2008-08-08)Tribofilms generated in wear tests using lubricants containing fluorinated ZDDP and ZDDP were studied. Fluorinated ZDDP demonstrated superior wear performance compared to ZDDP under tribological conditions even at lower ... -
Tribological Performance Of Ashless Antiwear Additives Under Extreme Pressure Conditions
Kim, BoHoon (Materials Science & Engineering, 2010-07-19)Zinc diakyl dithiophosphate (ZDDP) has been used in engine oil for several decades as an antiwear additive. However, ZDDP is the primary source of P, S and Zn in the exhaust, which results in frequent maintenance or ...
