Tribology, Lubrication & Coating Laboratory

TLCL was established over 15 years ago and has been funded by grants totaling over $1 million by Platinum Research Organization and The Texas Higher Education Coordination Board, Boeing Corporation, Lubrizol Corporation, Ford Motor Company etc. . There have been several major initiatives within TLCL that include:

  • Development of High performance low phosphorous engine oils: The goal of the project has been to develop engine oils that are low in phosphorous and yet maintain their high anti wear performance. The outcome of the project would result in better fuel economy and lower emissions
  • Development of high performance universal greases: The goal of this project has been to develop low MoS2 greases that have improved low load wear performance while still retaining its extreme load carrying capacity
  • Development of conformal large area fluorinated hydrocarbon coatings: A new method for coating large areas with PTFE using a catalyst to enhance the deposition of PTFE at low temperatures was developed. Applications include: low friction coatings for anti-icing applications, anti-corrosion coatings, low friction and wear coatings for MEMS applications.
  • Results developed from ongoing research has resulted in 12 patent applications with the US Patent office and over 30 publications.
