Samples of Current Research Activities

(a) Degredation of Onshore and Offshore Oil and Gas Pipeline Steels

Pipelines move nearly 75% of the oil transported annually worldwide. Pipelines are, by far, the most important petroleum supply line, including crude oil, and raw gas. In addition to their efficiency, pipelines also have important environmental and safety benefits. Pipelines are subjected to harsh environments and operating conditions that may cause failures with catastrophic consequences. One of the most common degradation processes is due to erosion-corrosion. The corrosion-related cost to the global transmission pipeline industry is approximately $50 billion annually, in addition to the irreversible damage to life and the environment. My research work in this area is focused on pipeline integrity in onshore and offshore environments. The work is funded by several major national and internationals grants. Highlights of Dr. Farhat's contributions in this area are next.

  • Quantified the synergistic erosion-corrosion effects in API X-series oil and gas pipeline steels. For example, it was found that during erosion-corrosion of API X-70 in CO2 environment, corrosion increases erosion by about 50%.

  • Discovered that, contrary to expectations, erosion under high particle feed rate, the velocity exponent ‘n’ (E=kVn) decreases with increase in impact angle. It was concluded that, under such conditions, the velocity exponent “n” becomes mechanism dependent.

  • Proposed plausible mechanisms for solid particle erosion as functions of abrasive particle velocity and impact angle.

  • Demonstrated that the reason behind the good adhesion of the initial FeCO3 passive film in API X-42 steel in CO2 environment is due to the anchoring of the corrosion layer by the pearlite phase.

  • Found that the commonly observed passive film that develops in API X-42 steel in sweet environment is actually made up of three corrosion layers. These layers are FeCO3 (primary), FeCO3 and Fe2O3 (secondary) and FeCO3, Fe2O3 and FeO (tertiary).

  • Demonstrated a significant sensitivity of carbon steel erosion to its microstructure. Analysis have shown that erosion rate is controlled by the type of microstructural constituent, orientation of pearlite plates and the angle of the impinging particle  with respect to the steel surface.

(b) Wear and Dent Resistance of Superelastic TiNi Bearings for Aerospace Applications

While superelastic TiNi alloys have been around for a while, they have not been fully exploited for tribological applications. Dr. Farhat's work is directed towards understanding the wear and dent behaviour of these unique materials for use in tribological applications. One potential application of these alloys is in high precision bearings for the aerospace industry. Superelastic bearings are expected to absorb the high impact loads experienced during space vehicles and aircrafts landing and take off. Dr. Farhat's research in this area has attracted the attention of researchers at NASA Glen Research Center and led to a collaboration that focuses on extending the use of superelastic materials to bearings in aerospace applications. Below are examples of Dr. Farhat's achievements in this area.

  • Discovered the existence of a relationship between loading rate and superelasticity under localized “indentation” loading. At high loading rate superelasticity drops by 10-15% accompanied by drop in dent resistance. This behavior can have serious implications in applications where superelastic TiNi is subjected to high impact loading.

  • Demonstrated that delamination wear is a dominant wear mechanism in superelastic TiNi due, in part, to the mismatch in the elastic properties below the surface.

  • Modified Oliver and Pharr method by incorporating phase transition effects, which take place during indentation, into the model. Oliver and Pharr method for calculating mechanical properties from load-indentation depth data is developed for single-phase material without phase transition. This method fails when extended to superelastic TiNi, as the effective elastic modulus for such material varies with indentation depth.

  • Demonstrated that new generation of aged and solution treated 60NiTi exhibit slightly enhanced superelasticity compared to equiatomic TiNi (i.e., lower E/H), yet they show about 3 times the hardness and about 40% improvement in wear resistance.

  • Developed a model to predict the temperature rise in the transformation zone during indentation of superelastic TiNi and found, contrary to long held understanding, that heat accumulation in the deformation zone during indentation is insignificant.

(c) Wear of Automotive Al-based Alloys

The research focuses on understanding and improving the wear resistance of light weight automotive Al-based alloys and developing novel surface treatment to protect lightweight materials’ surfaces against wear. Dr. Farhat's work in this area is performed in close collaboration with two leading companies in their fields, Vector Aerospace and Magna-PFC International. The work has resulted in the adaptation of surface treatment based on pulsating high-pressure waterjet process. This cost effective process can be applied locally to cast automotive components to enhance their surface tribological properties. Below are some of Dr. Farhat's contributions in this area. 

  • Developed a model to describe the effect of porosity (amount and size) on wear mechanisms and wear rate in Al-Si alloys used in automotive components.

  • Assessed the applicability of employing hot isostatic pressing (HIP) to mitigate surface porosity in A380M aluminum alloy in cast and powder metallurgy components. A 15% improvement in wear resistance was achieved through the  application of HIP.

  • Successfully adapt a high-pressure water jet (HPWJ) treatment to improve the tribological properties of Al-based alloys. The treatment resulted in 60% enhancement in wear resistance. The advantages of the newly adapted water jet technique are: low cost, no heating effect and can be applied quickly to selected surfaces without affecting the rest of the component.

(d) Contribution to the Understanding of Wear Processes

Throughout Dr. Farhat's career he has worked on many wear and friction related projects. The general aims of these projects were to understand wear mechanisms in different materials under variety of conditions; and develop surface treatments and coatings to mitigate wear. Examples of contributions are below.

  • Developed an understanding of the role of surface chemistry and diffusion of atomic species across tool-workpiece interface in high speed machining for cubic BN and WC-TiC-Co tools.

  • Developed a technique to monitor crystallographic anisotropy in Al and Ti alloys during wear, and discovered strong correlations between friction and wear and crystallographic texture evolution.

  • Successfully developed novel wear resistant nanocrystalline (Al, Ti, Cu), quazicrystalline (Al-Cu-Fe) and nanolaminated composite (Al/Al2O3, Ti/TiN, Ti/Cu) films using radio frequency triode magnetron sputtering system and reactive sputtering techniques.

  • Modified Archard’s law of wear in terms of Hall-Petch equation for nanolaminated composites.
