Tribology Laboratory - University of Pretoria
The tribology group is headed by Professor Philip de Vaal and was started in 1987 with support from ESKOM, Anglo-American and ISCOR. The activities in the lab focus on lubricant performance evaluation, which includes analysis of greases, oils and diesels. More recent industrial problems with diesel quality in South Africa motivated research in the field of diesel lubricity and biodiesel, sponsored by Sasol.
The Tribology Lab not only functions as a academic research lab, but also as an evaluation lab for industry. Several companies use the Tribology Lab for failure analysis and quality control.
The first section gives information regarding the equipment used in the Tribology Lab. The user manuals, test procedures and ASTM/ISO/DIN/SABS standards for each piece of equipment is included in the respective pages. Documentation of past and present projects can also be found there.
The second section includes all the work and some of the literature regarding hip tribology, and the third section has all the past |test results done for partners in industry. A password is required to access this page.
Section five gives access to all the ASTM/ISO/DIN/CEC/SABS standards and procedures that are not included in the equipment section. You will also need a password to access this page.
The last section contains all the project files and documents of students who worked on the diesel lubricity and biodiesel project.
