(2016-07-12)Adhesive wear is one of the most difficult types to study and is especially challenging for polymers. Such wear processes involve the mutual sticking of surface asperities followed by removal of debris from the bulk. This ...
-
The objective of this project is to study the effects of different surface textures and patterns on the wear mechanisms involved, and the cumulative damage on these surfaces. Laser surface texturing (LST) is used to ablate ...
-
(2021-07-12)Lubrication plays important roles in mechanical systems in motion. The challenge in understanding the characteristics of a lubricant under working conditions lies in its dynamic nature, and it is impossible to observe the ...

(2010-01-16)As alumina plays ever more important roles in advanced technologies, such as substrates for in vivo biological sensors, catalysts for water purification and components of novel fuel devices, it is exposed to various ...
-
(2019-11-21)Polymers are expanding their applications in the tribosystems. Easy machinability, excellent corrosion resistance, and convenient modifiability via various additives open new doors for their presence in unprecedented ...
-
(2022-05-26)Modern SFD designs are short in axial length to limit weight and part count and supplied with a low lubricant feed pressure to reduce operating costs related to lubricant storage and pumping power. O-rings (ORs) reduce ...
-
(2018-12-04)The scarcity of conventional oil reservoirs has led the oil and gas (O&G) industry to develop non-conventional extraction techniques such as extended-reach drilling (ERD) that brings new engineering challenges. Challenges ...

(2010-07-14)This research conducts tribological investigation in three areas. The first area of research is to obtain basic understanding of tribological properties of high performance Inconel alloys. Pin-on-disk testing was conducted ...
-
(2013-07-19)With increasing rotor flexibility and shaft speeds, turbomachinery undergoes large dynamic loads and displacements. Squeeze film dampers (SFDs) are a type of fluid film bearing used in rotating machinery to attenuate rotor ...
-
(2012-02-14)Tests are performed on a flexure-pivot-pad tilting-pad bearing with a series integral squeeze film damper in load-between-pads configuration, with both active and locked damper. The damper effects are negated when locked, ...
-
(2012-10-19)High performance machines such as gas turbine engines demand efficient solid lubricants at high temperature and in vacuum. The current conventional solid lubricants need to be further improved. This research evaluates ...
-
(2017-12-11)Polymers and their composites have favorable tribological performance such as low coefficient of friction (COF) and good corrosion resistance, when working as bearing materials. The present work is studying the tribological ...
-
(2020-01-23)It is of great interest to seek lubrications for friction minimization in order to save energy and thus reduce cost. Two dimensional MoS₂ exhibits promising friction reduction and anti-wear properties. Moreover, the use ...
