Abstract
The search for the development of new lubricants, especially those of renewable origin, is increasingly intense, so that Brazil cannot fail to participate in such a scientific/technological effort so as not to become even more dependent on imports of yet another product that has wide marketing use. In this sense, it is worth noting that, currently, mineral lubricants produced in Brazil depend on the import of around 55% of the Arabica base oil, in addition to almost all of the additives used to formulate the product. However, with the advent of new products, especially bioderivatives, it has become necessary to carry out a wide range of performance analyzes to identify whether or not a new product can be made available to the market. Examples of these bioproducts include biolubricants derived from vegetable and animal oils and fats and synthesized greases.Recently, the Chemistry Institute of the Federal University of Goiás, in research coordinated by Prof. Dr. Nelson Roberto Antoniosi Filho, developed soy-based biogreases, through a synthetic production route. (ANTONIOSI FILHO, N.R. et al., 2016). These bio greases have many superior characteristics to lubricants of fossil origin, but they still require performance evaluation such as, for example, in Pin on Disk tests with subsequent analysis of the results obtained in this equipment.There is a need to evaluate the properties of these bioproducts through tests such as TAN, TBN, Oxidation, Sulfation, Nitridation, Magnetic Particle Counting, X-ray Spectrometry and Analytical Ferrography. This is intended to demonstrate the suitability and/or superiority, in mechanical and environmental quality, of liquid and solid biolubricants derived from fatty oils, aiming to point out commercial, environmentally correct alternatives, with equal or better performance than fossil lubricants currently sold.This work is a partnership between Prof. Nelson and our Laboratory to assist in the analysis of performance and improvements in biolubricants developed at the UFG Chemistry Laboratory and those previously studied at the Unesp Tribology Laboratory.
