Introduction: The recruitment of leukocytes into the vessel wall intima plays a significant role in the onset and progression of atherosclerotic lesions. Imaging of VCAM-1 expression in atherosclerotic plaques may serve as a surrogate marker of inflammatory cell recruitment into plaques. The purpose of this study was to image VCAM-1 expression in carotid artery lesions of apoE-/mice, to compare...
Heat treatments are frequently used to modify the microstructure and mechanical properties of materials according requirements their applications. Laser surface treatment (LST) has become a relevant technique due high control parameters localization involved in modification. It allows for rapid transformation near surface, resulting minimal distortion workpiece bulk. LST encompasses, turn, lase...
Stalbaum, Tyler P., M.S.I.E., Purdue University, May, 2013. High Speed Turning of Compact Graphite Iron using Controlled Modulation. Major Professors: Srinivasan Chandrasekar and W. Dale Compton. Compacted graphite iron (CGI) is a material which emerged as a candidate material to replace cast iron (CI) in the automotive industry for engine block castings. Its thermal and mechanical properties a...
In this paper, the reasons of damage water pumps parts of the air compressor cooling system were studied. To reach this goal, the works like preparing metallographic samples, evaluation of structure, investigation of mechanical properties, the alloy parts detection and chemical analysis of deposit and corrosion products collected from the parts were performed. According to studies and results o...
In this study, a cladding layer and nitriding were prepared on nodular cast iron, to provide guidance for remanufacturing of iron. Their microstructure composition the tribological properties under dry starved lubrication conditions studied. Meanwhile, contact stresses at different friction stages simulated through finite element method. The micro-hardness 694 HV0.5 724.5 HV0.5, which 4 times 4...
